Installing MRTG on a Windows Platform

MRTG is the most popular open source performance measuring tool being used around the world today. While MRTG is open source, it has been widely adopted by major companies everywhere who use it to measure network performance and adherence to SLAs, among other things. For an interesting snapshot of who is using MRTG, and for what purpose, go to MRTG's “Where, What, How” page and have a look at some of the interesting things MRTG is being used to track. Although MRTG started out as an application to measure network performance on routers (MRTG stands for “Multi Router Traffic Grapher“), it is being used today to graph everything from traffic jams in the Netherlands to the local temperature in Wroclaw. If you can provide a numeric value to MRTG, it can produce a graph of it.

This article is going to take you step by step into installing a fully-functional MRTG system, and give you some pointers on where to go from there. We are going to take advantage of some handy shortcuts, for the sake of time. Some of the steps may seem a bit weird initially, but this is the quickest and easiest way to get up and running. And that is the point of this exercise.

We will be relying on a number of pre-compiled packages to get us up and running. You should go fetch them now and have them available when we need them:

Active State's Active PERL
Open Innovation's MRTG Bundle

I opted to use MRTG Bundle for a number of reasons:

It comes with RRDTool, the defacto standard for performance-minded MRTG installations
It uses Routers2.cgi for the web front-end, which is generally preferred over the default 14all.cgi.
It comes with a small installation of Apache, so you don't have to reduce the security of your IIS server in order to view MRTG's output. This Apache installation runs on Port 9191, so it will not interfere with any IIS installation already running (unless IIS is also running on port 9191, which would be unusual)
Includes GetIF, which is a very handy SNMP utility that we will use later to determine the appropriate OID to use within MRTG.
It comes with a number of very useful scripts for managing new devices (though we will enhance these slightly)
It comes with UNIX-like Cron, which is much more reliable than Windows' built-in scheduler service when it comes to running tasks once a minute.
It's dead easy to install

While MRTG also includes a set of PERL binaries, there are a couple things included in Active State's full PERL that we will be relying on in some of the more advanced tasks later on.

So, let's get started:

Make sure the system you will be running MRTG on has SNMP enabled. Set the Read community to something obscure, and not easily guessed. For the purposes of this demonstration, I will use the default “public“ for the Read Community. You should use something more complicated. You should also ensure that remote systems cannot query your SNMP service for information unless you explicitly allow. These are all properties of the SNMP Service's property page, Security tab. Screen shot is available here.
Install Active PERL, taking the defaults. Reboot after installation.
Execute the MRTG Bundle installation package that you downloaded from Open Innovations.
Read and accept the GNU public license.
DO NOT accept the default installation location. If you read the instructions on the page, you will notice they want you to install to “C:\“. Enter “C:\“ in the text box where “c:\mrtg“ is suggested.
Once the installation directory is correctly set to “c:\“, hit Install and observe the files being placed in the appropriate directories. This will take some time, there are a lot of files.
Once finished, you should be left with an MRTG directory on your C drive.
If you have a list of routers or other network devices that you want to have auto-detected for you, edit the c:\mrtg\mrtg\bin\myrouters.txt file. Put each device on a separate line, using the format communitystring@IPAddress. For instance, if you have a router at 10.0.0.1, with a community string of “public“, you would put public@10.0.0.1 in the myrouters.txt file. The initial entry (communitystring@ipaddressofserver) is there just for instructional purposes and should be replaced with a real entry. Entries in this file will be scanned during the next step of the installation, and an MRTG config file will be automatically generated during the next step of the installation. This is particularly handy with switches, where the large number of ports are tedious to configure manually within an MRTG config file. For the purposes of this demonstration, I am listing 2 of my Cisco switches, which are configured for the default “public“ SNMP community. My myrouters.txt file can be viewed here.
Once your myrouters.txt file is complete and saved, open a command prompt and navigate to the c:\mrtg directory
In c:\mrtg, execute the “install.bat“ file.
Hit ENTER after reading the introduction screen. Note the warning that all input must be given in LOWER CASE during this installation process.
Answer “y“ to the question about installing SNMP4W2K on the local machine (you can say no to this, but it gives you a good starting point on making config files for Windows servers), then hit ENTER.
Enter a 1 or 2 when asked how many CPUs the local computer has, then hit ENTER.
A new command window will launch, starting the installation of SNMP4W2K. Follow the prompts to complete that installation.
When the SNMP4W2K install is complete, the command window will close, and a Readme file is displayed. You can safely close that, or read it. Your call.
Notice our original command window has been patiently waiting for us to tell it that SNMP4W2K has finished installing.
Hit ENTER in the original command window to proceed with the MRTG installation
It will prompt you about the MyRouters.txt file. Enter “y“ here if you have configured one as I instructed in Step 8, otherwise enter “n“ and hit return to proceed.
Verify the installation options, enter “y” and hit ENTER to proceed with the installation.
The installation script will proceed to build your initial set of config files, querying the devices you specified in the myrouters.txt file for various interface information. It will then start the necessary services (Apache and Cron), and installation is complete
Open your favorite web browser, and point it to http://localhost:9191. You should be presented with a screen that resembles this.
Congratulations! MRTG is installed. You've earned a Fat Tire.

Upgrading MRTG:

Before you go much further, you will want to upgrade to the latest version of Routers2.cgi and RRDTool:

Upgrading Routers2.cgi:

Go to Routers2.cgi's home page and download the latest version of Routers2.cgi. Note that the current release version has a security flaw, so we will be using one of the Beta versions, v2.14-beta7. These versions roll often, so the link to Beta7 may be old by the time you read this. Use whatever the latest version is.
Unzip the files to your c:\MRTG directory (it will create a directory called routers2-v2.14 as a result)
Open a command window and navigate to the c:\mrtg\routers2-v2.14 directory
Execute the following: perl install.pl (note the following instructions may become inaccurate as future Routers2.cgi versions are released)
Hit Enter to continue past the introduction screen
You may receive warnings of various libraries not being installed. If you have installed the latest version of Active Perl, as I suggested, it is safe to ignore these warnings.
When it asks what drives to check, accept the default of “C“ and hit ENTER
When it asks where you web root is, DO NOT ACCEPT THE DEFAULT. In most cases, the default will be c:\inetpub\wwwroot, which is incorrect. Our installation has put our web files in c:\mrtg\wwwroot. So type that in and hit ENTER.
Enter the same thing for the question about where the CGI files are kept: “c:\mrtg\wwwroot“ and hit ENTER
The next question is about the location of the MRTG config files. Enter “c:\mrtg\mrtg\bin“ and hit ENTER
The next question is about the names of the config files themselves, it is safe to just hit ENTER on this question, taking the default of “*.cfg“
Next it wants to know where the RRD database files are being held. It defaults to c:\mrtg\wwwroot, which is correct. Just hit ENTER.
Next it wants to know where your perl.exe file is located. It will default to c:\mrtg\perl\bin\perl.exe. Accept the default and hit ENTER
Next it asks where your routers2.conf file is located. Although it warns you not to change the default without a good reason, ours is located in c:\mrtg\mrtg\bin\routers2.conf. Enter that in and hit ENTER.
Accept the defaults for the next series of questions (“Activate Routing Table Extensions?“, “How big should K be?“, “Do you want to use authentication?“ and “Can I email the author?“). Feel free to say YES to the emailing question, if you have ready access to a mail server.
Then you will be presented with a summary of the options we have just set, and asked if it's OK to proceed with the installation. Hit ENTER to proceed unless you have made a mistake somewhere along the line.
When asked if you want to overwrite routers2.conf, say “yes“ and hit ENTER
Hit Enter again at the “All Done?“ prompt
Copy \mrtg\wwwroot\index.cgi c:\mrtg\wwwroot\index_cgi.bak
Copy \mrtg\wwwroot\routers2.cgi c:\mrtg\wwwroot\index.cgi
Run “net stop apache“, then “net start apache“ to restart the web server.
You're all done with upgrading Routers2.cgi. Have another Fat Tire.

Upgrading RRDTool:

Go to the RRDTool distribution page and download the latest Win32 binaries (currently v1.0.48)
Unzip them into c:\mrtg\rrdtool\update
Open a command prompt and navigate to c:\mrtg\rrdtool\update\src
Copy the .exe files from each of the 4 “*_release“ directories (tool_release, stats_release, rrd_cgi_release, and bounds_release) to c:\mrtg\rrdtool, overwriting the files that were originally in that directory.
You're done. What the hell, have another Fat Tire!

Tweaking Routers2.conf:

When we upgraded to the latest version of Routers2.cgi, we lost a couple things that we want to get back. One of them was the 6-hour graph, which is now disabled by default. Also, the scale of the graphs is wacky, and shows the maximum possible values at the top, instead of scaling smartly based on the data coming in. This makes for much less useful graphs, especially in environments where the traffic levels are such that they don't even seem to register properly on the graphs.

So, open c:\mrtg\mrtg\bin\routers2.conf in your favorite test editor (TextPad is mine), and make the following changes:

Change the line #unscaled = no to unscaled = no, removing the comment tag “#“
Change the line #6hour = no to 6hour = yes, removing the comment tag and changing the value to yes
If you want 95th Percentile calculations that show the 95% average value over the course of a given graph, remove the # in front of the line #percentile = yes. This can consume a lot of your system's CPU time on a machine monitoring a lot of devices, so don't enable it in environments where you expect the MRTG machine to be working hard already.
Uncomment #windowtitle and #pagetitle directives, and set them to something appropriate for your environment. This will change the default page heading from “Router Monitor“ to whatever you enter here.
Uncomment #withdate = yes to show the dates on the graphs when they were last generated. This is useful for troubleshooting an MRTG problem.
Close your editor, saving changes. The changes will be reflected the next time you refresh your web page.

Adding Devices to MRTG:

Adding devices to MRTG is a 2-step process. First, a new .cfg file must be created for the new device. Then Cron must be configured to regularly poll the device for the graph data. Remember, Cron is the facility we are using to query the devices every minute for metrics.

In the c:\mrtg directory, you will notice a number of handy batch files left behind by the Open Innovations bundle we initially used to install MRTG:

Update_MyRouters.bat: This batch file will process the c:\mrtg\mrtg\bin\myrouters.txt file as if they were there during the original installation. A basic cfg file will be built for the device automatically.
Manually-run-mrtg.bat: This batch file will run the MRTG process on the localhost.cfg file that was created during installation. This is the exact command that Cron runs every minute on each of your MRTG targets to fetch data for the graphs.

While these batch files are helpful, I found it easier to modify them slightly for my own use:

In the manually-run-mrtg.bat file, I replaced “localhost“ with “%1“, which allows me to run the batch file with any cfg file I specify on the command line. I also renamed it to something shorter, for usability reasons. It is now called “UpdateMe.bat“, and you can view it here. I execute it by running Updateme.bat . For instance, if I was making some tweaks to the 10.0.0.252.cfg file, and I didn't want to wait for Cron to get around to updating things, I would just execute updateme.bat 10.0.0.252 and the graphs would be updated immediately in MRTG.
I wanted an easy way to add a new device to MRTG without having to go through the myrouters.txt thing. I have enough devices around now that I can usually use an existing cfg file for the new device, instead of having to go through the whole process of generating a fresh cfg using Update_MyRouter.bat. So I made a shortcut batch file for that too, called NewCFG.bat. You can see it here. You must specify the name of the cfg file (without the .cfg extension) at runtime. For instance, if you had a new cfg file called “NewDevice.cfg“, you would run NewCFG.bat NewDevice and it would run the initial MRTG and add the device to the crontab.

Routers.cgi Directives in the device.cfg Files:

I've shown you how your can customize MRTG's display by diving into the Routers2.conf file. If you look through the file, you will see there are many options you can tweak with, and it is fairly well documented.

However, I prefer to use the cfg files for the individual devices to make the majority of my tweaks. And with the latest version of Routers2.cgi, it's terribly easy to do so.

Let's say we want to change the default icon for my Cisco 2916 switch at 10.0.0.252. There are a bunch of icons already made for you in the c:\mrtg\rrdtool\rrdicons directory. I want to change the icons for my Cisco device to a small Cisco icon, which is made available as “cisco-sm.ico” in the rrdicons directory. I also want to change the menu from displaying “10.0.0.252“ to something more friendly, like “2916M-XL“. Here's how it's done:

With your favorite text editor, open the device's cfg file, in this case it's c:\mrtg\mrtg\bin\10.0.0.252.cfg
In the section towards the top, where the Global Defaults are set, add a line that says routers.cgi*Icon: cisco-sm.gif
Add another line that says routers.cgi*ShortDesc: 2916M-XL
Save the file.

The next time your web site is refreshed, it should reflect the changes.

A full list of Routers.cgi directives, and what each does, can be found here.

Conclusion:

I hope I've given you enough information here to get started with MRTG on Windows, and some insight into the potential of the system. Follow-up articles will go into more detail about the configuration options available within the cfg files, as well as how to use WMI and Performance Monitor to query Windows systems for more advanced metrics.

Update: Be sure to read this important follow-up about an error some folks are getting after upgrading to Perl 5.8.1 or later.

# re: Installing MRTG on a Windows Platform 7/1/2004 1:20 PM Stephen

I am still having the same error as stated above but my real problem was the --ifref global option listed in the .cfg file. It would chocke on that option and comment out my entire cfg. So I edited the updateshellscript.pl (c:\mrtg)file and removed the --ifref option.

All is working fine...except for the "Possible precedence problem on bitwise" What ever that means.

Just found this site, very detailed procedure.

Anyone who is having problems with the routers2 frontend, should check out the forum at steveshipway.org/forum for help and advice.

Also, since the MRTG Bundle is getting more and more popular, I am reconfiguring the install.pl script for routers2 to detect it and default appropriately (making your upgrade job detailed above easier). This will be available from v2.15b6 and onwards.

Kudos to Beau for the articles!

# re: Installing MRTG on a Windows Platform 11/17/2004 11:32 PM Nick

I recently installed the MRTG Bundle v2.1.0 on a Win 2K3 Server and I am getting what seems to be a Perl error every time MRTG attempts to run. I am running MRTG as administrator so I don't think it's a permissions issue. The entries in the mrtg.log are as follows:

2004-11-17 23:23:52 -- Started mrtg
2004-11-17 23:23:52 -- readline() on closed filehandle NF at c:/mrtg/mrtg/bin/mrtg line 1019.

If anyone has run into this problem I would greatly appreciate a pointer in the right direction.

I have the same problem as nick nick did you ever figure out how to fix this problem
readline() on closed filehandle NF at mrtg line 1019.

# re: Installing MRTG on a Windows Platform 12/1/2004 8:07 PM Paul Wozney

I managed to make the errors go away.

I edited c:/mrtg/mrtg/bin/mrtg:

#open NF, "$$cfg{'workdir'}${main::SL}$$rcfg{'directory'}{$router}$router.95";
open NF, "$$cfg{'workdir'}$router.log";

It looks like it's a misconfiguration in the script.

However it's a bit late and I'm hungry so I'm not entirely certain this is going to work that well; but I thought I'd get you guys on the right track to hacking your own mrtg install.

Hi Beau,

I just installed the MRTG following your lead and it installed all right on the first shot.
Thanks a million!!!

But... (there's always a but)

I know it's not a big issue but its quite annoying once I'm monitoring the machine where I work. Is there any way to hide the DOS window everytime the cron runs?

Or, if not, can I change the settings on the crontable to the, let's say, scheduler? (I know it's a sacriledge.. but hey we're running Windows, huh?)

Thanks a million once again...

Then it worked. Also used your suggested bitwise fix.

I'd like to see more information on how to monitor windows systems with MRTG, expecially by grabbing perfmon counters.

# re: Installing MRTG on a Windows Platform 2/22/2005 10:40 AM Greg Dzurinda

I am having issues after the install. Thought it went smooth, but when I go to IE and type in http://localhost:9191, I get the following error when I choose localhost:
----------------------------------------------
CPU1

Error reading RRD database c:\mrtg\wwwroot\cpu1.rrd

You can visit the configuration verification page here.

File: [localhost.cfg] localhost
Target: CPU1
Target list: localhost.memoryUsed, storageUsed-C, CPU1
-----------------------------------------------

When I look at the configuration verification page, everything looks fine except I get this error under the "MRTG Targets Check":

Hello, I cant seem to figure out what option to give perl cfgmaker. I have a Dynamic IP alloted to me.I use RASPPPoE for win2K to dial over ethernet(PPPoE) and get a dynamic ip.
I cant specify hostname or ip since the ip changes every time i dial out. I would like to specify based on --ifref=nr --ifref=eth

# re: Installing MRTG on a Windows Platform 4/7/2005 2:09 PM Frank

Hi, I found my MRTG only work well with the localhost(my test PC with windows XP), the other network deivces for the testing - tow san switches - never ever appear.
I found the cfg files for localhost and swithcs are different in c:\mrtg\mrtg\bin.
the cfg file for localhost likes the following:

# re: Installing MRTG on a Windows Platform 4/13/2005 3:14 AM Yus

so far so good..have installed mrtg and able to run ..but noticed though the following errors on da bat files:

Useless use of a constant in void context at c:/mrtg/bin\..\lib\mrtg2/BER.pm line 355.

Anyone has any idea whats causing it?

# re: Installing MRTG on a Windows Platform 4/19/2005 10:30 AM Travis

I just wanted to say a great big "THANK YOU!" I've been using MRTG's basic format and recently stumbled across this site by fluke. I now have a second instance of MRTG running the bundle package and it is So much more advanced!! You guys Rock!

# re: Installing MRTG on a Windows Platform 4/20/2005 10:24 AM Travis -- again

Despite my initial enthusiasm I’ve hit a snag. Everything seems to set up fine with my one router in my routers.txt. However I’m trying to add a UPS device we use for monitoring Temperature and voltage (I know it CAN be done, we have the basic MRTG monitoring it now).
If I add the community string and IP to the my routers.txt I get the infamous “precedence problem” error. I’ve run the fix and now I’m getting “The following interface is commented out because:=* --ifref=name is not unique for this interface” issue.
I’ve tried the fix mentioned by Stephen “# re: Installing MRTG on a Windows Platform 7/1/2004 1:20 PM”
Now I’m getting “Error reading RRD database c:\mrtg/wwwroot\(IP Address Here).rrd
opening 'c:\mrtg/wwwroot\(IP Address Here).rrd': No such file or directory” and sure enough there is no rrd file for this device.
Is there some way to fix this? Why am I not getting an RRD file for this device?

# re: Installing MRTG on a Windows Platform 4/21/2005 10:21 PM Vasant Gaonkar

Hi,
I have a query regarding Adding new device to Mrtg.Whenever I add new device in Myrouters.txt then i have to run Update_MyRouters.bat file which starts the entire process again.

By doing this My previous configration gets deleted ie changes made to devices.cfg file gets deleted and i have to manually change it Again.

Is there any Solution for only changing the new device added.

# re: Installing MRTG on a Windows Platform 5/13/2005 6:17 PM Bob Farrell

Can not extract any routers2.cgi file higher than than v2.14-beta7.

Thoughts ?

# re: Installing MRTG on a Windows Platform 5/18/2005 12:56 PM TS

Thank you very Beau. I am so glad to have found this information. We were using plain MRTG prior to this and this sure is better!!

I followed your directions to a "T". I found a few minor issues which I have worked through. I have updated all additional packages (Perl, Routers2.cgi, RRDTool, etc.) to the latest versions. Everything appears to be working great except for collecting data from localhost (receive the errors "Error reading RRD database c:\mrtg\wwwroot\cpu1.rrd" "opening 'c:\mrtg\wwwroot\cpu1.rrd': No such file or directory", "Error reading RRD database" "c:\mrtg\wwwroot\storageused-c.rrd
opening 'c:\mrtg\wwwroot\storageused-c.rrd': No such file or directory" and "Error reading RRD database c:\mrtg\wwwroot\localhost.memoryused.rrd"
"opening 'c:\mrtg\wwwroot\localhost.memoryused.rrd': No such file or directory", these files just don't exist.) I've checked local SNMP configuration, all seems good. I'm running on Windows 2000 Server w/ latest service packs, critical and security updates installed.

Any ideas?

Second major problem is that on one of our WAN routers (we have two currently configured), which is a Cisco 3745, we do not get any data collected for the #Se0/0:0 thru #Se3/1:0 interfaces (about 8 total). I've checked through the .cfg files and all looks good. The charts show up, but all is blank. The in and out is listed as follows:

In: Max -1.#J , Avg -1.#J , Last -1.#J
Out: Max -1.#J , Avg -1.#J , Last -1.#J

Any ideas?

Thank you again!

# re: Installing MRTG on a Windows Platform 5/18/2005 9:22 PM TS

Here's a quick update... The Cisco 3745 router T1 serial interfaces had a colon (:) in the name, like s0/0:0 and s0/0:1, etc. And, somehow when the original .cfg files were built, instead of sticking one backslash (\) before the colon, there were two! I removed one of the backslashes and it is working.

Now I just need to figure out the problem with "name is not unique for this interface" that I'm getting for my firewall! oh, and that strange localhost problem (nothing displayed).

Thanks again!

# re: Installing MRTG on a Windows Platform 6/17/2005 2:55 PM trevor

fixed the

### * --ifref=name is not unique for this interface

error for my devices...

http://mrtg.hdl.com/cfgmaker.html

The Update_MyRouters.bat calls the updateshellscript.sh, which in turn runs the cfgmaker to make the config files. The updateshellscript.sh (found in c:\mrtg\) calls cfgmaker with the --ifref=name flag. I changed this to --ifref=nr (the default) and it fixed my problems.

# re: Installing MRTG on a Windows Platform 6/20/2005 3:02 PM Wil

You may need to update both the shellscript.sh and updateshellscript.sh to point to the correct Work Directory in order to see the rrd files. Make sure it points to the following:
workdir: c:\\mrtg\wwwroot instead of c:\\mrtg/wwwroot.

# re: Installing MRTG on a Windows Platform 6/27/2005 7:28 AM Matt

Beau first I would like to say this is great and my hat is off to you for puttig together a great set of instructions on how to get this MRTG deployment up and running.

Everything appeared to be working correctly until I started to put a load onto the server running this package. I have "roughly" 215 devices that I need to monitor with several interfaces on each. It appears that the perl.exe resource is consuming over 95% of the servers resources. I have set the priority on this service to low; however, the box is still overwhelmed. Currently it is running on a 2kS/700mhZ/500M RAM. Do you have any suggestions on tweaking perl.exe or suggestions on the hardware requirements?

Again thank you very much for putting this all together.

Can you monitor pc's and servers using rdtool and routers2.cgi.

If yes can enter the device details in the routers.txt file to create the cfg file.

Please advice me

# Obtain OID via Win2003 9/6/2005 12:06 PM asingh

Hi,

I have installed the bundle from Open Innovation's and have MRTG/RRDTool running. The cfg file only had the NIC in the system, I have tried to use Getif to obtain the CPU OID but I am still having problems getting the CPU working, I have not even tried to get mem or disk section working yet. I also have SNMP-Informant installed. I am not sure if I am using the correct OID...(How to know for sure?)

The graph that is displayed for the CPU does not change values, Max,Avg,Cur Load are always at -1%. The time updated on the page

Here is a cfg I have been testing with,

I am getting the following errors when running the Update_MyRouters.bat file. I changed the
the ifref=name to ifref=nr in the updateshellscript.sh file figuring that may be it.

btw, i had this running before on all my servers on my lan before (memory doesnt serve me well what i did to fix any errors i ran across before to make it work).

C:\mrtg>Update_MyRouters.bat
This script will add any new routers or switches that you've put
into the c:\mrtg\mrtin\myrouters.txt file.

Please note, that this script will create a new crontab file
based on all the config files in c:\mrtg\mrtin\*.cfg.
Any custom changes you've made to the crontab file will be lost.

Example myrouters.txt:
public@localhost
public@router1
secretcommunitystring@switch1
etc.

Do you want to update MRTG with the new myrouters.txt file? (y/n) -->

You need to delete the .cfg and .ok files from C:\mrtg\mrtg\bin and also make sure to remove this from your crontab file as well.

Follow the steps listed below:

I've found the solution, after much investigation.

Open BER.PM in your favorite text editor and change line 619 to read:

return error ("Sequence expected") unless $result == sequence_tag or constructor_flag;

Save the file, and you're golden.

# MRTG on a Windows Platform modifying default global parameters. 12/21/2005 1:01 PM Terry Flannery

Hi Beau,

First off, I'd like to thank you for the information that you have provided, Thank you!

I have a router where the interface name and description fields are blank and I want to set the default global parameter to ifref=ip, however, when I update the router.cfg file and then run update-my-routers.bat it gets overlayed with the default ifref=name and consequently all the interfaces are commented out. Is there a place that I can change the default (for a specific router of for all routers)?

Many Thanks,
Terry Flannery

# re: Installing MRTG on a Windows Platform 1/7/2006 12:55 PM tony

I have read through your instructions but I still do not understand how all of this applies to running SMNP-gets and graphing?
How do I run Cron to update my graphs every minute or sooner?

I am new to all of this....and clueless

How does Apache play into all of this?
I am running WinXP, SP2.
What does Cron do and how do I use it?

My goal is to poll wireless radios from different sites to get their SNR values. I know how to do this using MRTG but I wanted to be able to graph every minute or sooner if possible.
I read that RRDtools allow for this. But I have no clue on how to use the RRDtool with MRTG to accomplish this.
I downloaded the MRTG bundle but I have no clear instructions on how to operate and use this tool. Any help you can provide would be greatly appreaciated.

Thanks
Tony

# Support Forum 1/10/2006 7:26 PM Steve Shipway

There is a support forum for routers2 at http://www.steveshipway.org/forum/
This also has a forum for MRTG and another for anyone using the Open Innovations bundle install (which has a whole slew of extra and non-standard things in it).
Although this forum is primarily for routers2 only, there are people online who can help out with other windows-related or bundle-related problems. Might be of assistance to people, since Open Innovations seem unable or unwilling to provide any support at all for the bundle.

# Upgrading routers2.cgi 1/10/2006 7:28 PM Steve Shipway

routers2 is now at version 2.16. The install.pl script with this version can usually spot the Open Innovations bundle install, and will set up its defaults appropriately. This should make the upgrade task a bit easier.

I also get the same errors when I added more devices, from 5 to 30 on a P3 1Ghz machine. I noticed the cpu was 100% utilization before the mrtg gave up and crash within 2 minutes. My guess is that the bundle can't handle too many devices.

Anyone knows of any fix(s) ??

# re: Installing MRTG on a Windows Platform 2/21/2006 1:09 AM Florus

I solved the perl.exe (0x0000142) error.
The solution is to use wincron instead of cron with the -wait command.
Step-by-step:
First disable the cron service, then install wincron.
wincron can be found at:
http://www.tomasello.com/software/wincron/
install wincron as a service (see readme)
Use the following user.tg script:
# MRTG cfg files loop
{
-start -inc 0 0 1 0
-action -foreach -file "c:\mrtg\mrtg\bin\*.cfg" THE_FILE perlscript
}
{
-name perlscript
-action -spawn -wait -hide CMD.EXE "/C c:\mrtg\perl\bin\perl c:/mrtg/mrtg/bin/mrtg --logging=c:/mrtg/mrtg.log c:/mrtg/mrtg/bin/%THE_FILE.FNAME%.cfg"
}
And if you plan to add more switches in the future (and don't want any errors appearing) add a # to the start of the "net stop" and "net start" lines in c:\mrtg\updateshellscript.sh

The trick is that cron spawn all perl tasks at once and when you spawn more than 10-20, an average system starts swapping, stalling and in general failing tasks, hence the pel.exe error. The above solution solves this by starting one perl script at a time and waiting for executiion.

Thanks for taking the time to do this. :)

# re: Installing MRTG on a Windows Platform 7/27/2006 2:37 PM NetCog

I'm getting it figured out thanks to this and a couple other sites. Another 'bug' / install watch I found along the way at least with mrtg version 2.9.27 :

XP command prompt
C:\mrtg\mrtg\bin>perl mrtg server.cfg

Can’t locate loadable object for module RRDs in @INC (@INC contains: C:/mrtg/mrtg/bin\..\lib\mrtg2\ c/mrtg/mrtg/bin\ C:/Perl/lib C:/Perl/site/lib .) at mrtg line 225

Compilation failed in require at mrtg line 225

SOLUTION: copy the rrds.pm to those directories where it doesn't exist. I had to place a copy into
c:/perl/site/lib
c:/mrtg/mrtg/lib/mrtg2

I think I copied but it could have installed to
c:/mrtg/mrtg/bin

and I think the command referenced in 2/16/2005 12:54 PM Tolli's comment installed it to c:/perl/lib

Also not sure if this is shown above but go into routers2.conf and look for "bytes" to uncomment a line so you can see the graph in bytes not bits.
You also need to comment out or delete the Options[_]: bits,growright line in your server.cfg

After the above fixes I reran c:/mrtg/mrtg/bin>perl cfgmaker public@server >server.cfg

This makes a clean cfg file but you'll need to copy in
#########################
Interval: 1
PathAdd: c:\mrtg\rrdtool
LogFormat: rrdtool
WithPeak[_]: ymw
workdir: c:\mrtg/wwwroot
#Options[_]: bits,growright
#########################

I placed it above the System information of the device.

# re: Installing MRTG on a Windows Platform 7/27/2006 2:41 PM NetCog

I also told it to not to the 95 percentile in the routers2.conf, it definately takes up memory and cpu. Why I would want it is a subject of a later search but unless the machine is just sitting there, or you have great stats, having memory and cpu jumping significantly every minute can cause a headache if you're trying to do other work.

Windows users...DO NOT USE THIS TUTORIAL. You will have nothing but problems. This information is severely outdated. MRTG + RRDTool is not worth your time. Use PRTG instead. It is SUBSTANTIALLY more informative and useful and infinitely easier to work with than MRTG.

Hi Beau,
I have successfully installed mrtg bundle and followed the above discussions to clear out some of the issues. Thanks. The provided info was great.

However, we are having a problem on internal serial frames on one of the routers. This router is the only one that has both FastEthernet link for the Internet and Serial connections used for internal frame relays. The FastEthernet connection works as expected, but Serial frame relays although the grid exist, the graphs are empty. This is a Linux based router. Can someone help me to figure this out? I am not very literate with Linux/Unix and have very limited scripting experience.

Any help is greatly appreciated.
