My apology PageTop missing H1 should set up as
PageTop[localhost.cpu]: Active CPU Load % for cpu.cfg
PageTop[localhost.mem]:Free Memory for mem.cfg
PageTop[localhost.memory]: Free Memory for memfree.cfg
PageTop[server.mempercent]: Percentage Free Memory for mempercent.cfg

It worked with translated textual MIBs to OIDs, PageTop missing H1 error was corrected by specifying PageTop[localhost.cpu]: Active CPU Load % correctly for cpu, mem, memfree and mempercent configuration files, and lastly indexmaker worked by using only *.cfg files (below at the bottom).

should we create the /etc/mrtg/cpu.cfg /mem.cfg /memfree.cfg /mempercent.cfg
/disk.cfg files or they are somewhere already present ? cannot go ahead to monitoring disk, memory and cpu but only traffic analysis ? I am stuck here can anyone help from here ? I guess the tutorial lags proper explanation regarding these, Can anyone help in this matter, I googled for some time but cannot come up with a solution to cpu, disk, memory anylysis.

Thanks in advance.

Hi there,

Tried installing MRTG on Debian Etch with the standard installation instruction. As per the instruction, I think the RunAsDaemon=yes should be set to RunAsDaemon=no. The reason is that if you set RunAsDaemon to yes and put a cron job to run every 5 mins, it will complaint with this message
==> mrtg/mrtg.log <==
ERROR: I Quit! Another copy of mrtg seems to be running. Check /etc/mrtg.pid

Not sure why nobody notice this.

Regards.

Hi all !

When I finished the installation using this guide, after I rebooted my box, I wait for a few minutes and then start the MRTG page… but all I can see is the MRTG-logo which is a link redirecting me to the MRTG website… so I don’t get any graph on my MRTG homepage.

I had no errors during installation.

I also wanted to check the config files for monitoring purposes, but it seems no MRTG map was created in etc/… did I do something wrong ? did I not do something ? did I miss something ?

Thanks for any help anyone can provide

Ch33rz,
Troma

For the problem

“Use of uninitialized value in hash element at /usr/bin/indexmaker line 352″

Before do indexmarket you need connect the linux server to the network, and you need make a ping from linux server to other workstation for traffic generation. Try againg cfgmaker , indexmaker and mrtg commands.

the permission denied error when running indexmaker comes from omitting one of the backslashes at the end of each line. if you’ve written this to a script as i have, bash is trying to run the next line (after the missing backslash) as a command. as your cmd files are not chmod +x, they won’t run. to resolve, add the necessary backslashes.

I was good up until the, “examples how to monitor cpu, memory, disk usuage”.
These examples, should I create the /etc/mrtg/cpu.cfg /mem.cfg /memfree.cfg /mempercent.cfg
/disk.cfg files? Or are these already created? Should I just copy and past what is listed
above for these .cfg files? Is there anything I need to change to be specific for my devices?

Also the “Creating Jobs for CPU, Memory and disk usuage”, do I create these files , the one for
cron.mrtg/cpu /mem /memfree /mempercent /disk. I am using Ubuntu, which is very similar
to Debian. I can not seem to locate any of these files in the locations were you said they were
located. Not to mention when I did try creating them, it said permission denied.

Please help. I have MRTG up and working, and would like to tie up the rest soon.

In response to jamie:

Make sure that you don’t have an extra line break. That should all be on one line in the cfg file.

hi Thanks for the tutorial.

Am experiencing a problem when I run:

/usr/bin/indexmaker -output=/var/www/mrtg/index.html -title=”Memory and CPU Usage” /etc/mrtg/cpu.cfg

I get the following error:

ERROR: CFG Error Unknown Option “sscpurawnice.0&sscpurawnice.0″ on line 5 or above.
Check doc/reference.txt for Help

Any ideas?
