HOWTO: Compile, configure and run MRTG

How do I configure this to also graph my load average at various times of the day?

Currently it is doing only:
Incoming Traffic in Bytes per Second
Outgoing Traffic in Bytes per Second
 
I've done this before w/o problems, but that was on redhat. I'm using CentOS now, and I get this when i try to run mrtg w/ the mrtg.sh file.

I get:
ERROR: Line 3 (INFO=`grep eth0 /proc/net/dev | tr -s ' ' ' ' | cut -d: -f2`) in CFG file (/mydirectoy/mrtg.sh) does not make sense


Any ideas?
 
post the output of

proc/net/dev

and I'll compare it with /proc/net/dev output from a working RHL 9 distribution and we'll figure out the differences.

Re: Quick install for RH9

Hi Guys,

I have a fresh install of Fedora 2 and yesterdays update of DA. The only other apps I have installed are afp, bfd, mod_dosevasive and webmin.

Okay so far so good :)

I used the method below to install mrtg and it installed okay. But some of the stats are wrong :confused:
The config & system file I am using is from this archive that is in the tutorial below:- http://people.ee.ethz.ch/~oetiker/webtools/mrtg/pub/mrtg.tar.gz

Here is a link to my mrtg on my server:-
http://sirius.xplic8.com/mrtg/

As an example:-
In the system file there is this block of code:-
Code: 
if [ "$TYPE" = "swap" ]; then
    INDATA=`cat /proc/meminfo | grep "Swap:" | sed 's/ * / /g' | cut -d ' ' -f2`
    OUTDATA=`cat /proc/meminfo | grep "Swap:" | sed 's/ * / /g' | cut -d ' ' -f3`
fi
Now I am a noob but I think this is piping the output of cat /proc/meminfo where it finds the word Swap:. But if I type cat /proc/meminfo at the command line I get this:-
Code: 
MemTotal:      1033928 kB
MemFree:         24420 kB
Buffers:         55640 kB
Cached:         765996 kB
SwapCached:      11144 kB
Active:         470176 kB
Inactive:       481332 kB
HighTotal:           0 kB
HighFree:            0 kB
LowTotal:      1033928 kB
LowFree:         24420 kB
SwapTotal:     2048276 kB
SwapFree:      2021236 kB
Dirty:             196 kB
Writeback:           0 kB
Mapped:         142748 kB
Slab:            46216 kB
Committed_AS:   379580 kB
PageTables:       4432 kB
VmallocTotal:  3088376 kB
VmallocUsed:      4388 kB
VmallocChunk:  3082432 kB
HugePages_Total:     0
HugePages_Free:      0
Hugepagesize:     2048 kB

But there is not a line that starts with Swap:?

I also have this problem with the memory part and cpu use.
Are there any updated files that will provide stats like this tutorial but on a Fedora 2 system?

Many thanks for any help.

Regards
Stephen

This will give you the graphs of the rpm version, but with the latest MRTG.

The major change from the original howto is the added configuration switch.

how do I delete mrtg 2.1.11 from my server?
I want to install a new version, but first I most delete the old one.

I have mrtg installed by help on this forum.
 
in my server it's working great :]

Code: 
Max Questions:   	100.0 q/s  	 	Average Questions:   	62.0 q/s  	 	Current Questions:   	91.0 q/s

hi, how can i update mrtg? I just add a new stick of 5412 MR ram, but when mrtg refreshing i still see 512 mb ram, not 1Gb help
 
That's either a lot of RAM or a typo :) .

Have you checked your RAM from the command line?

Run:

cat /proc/meminfo

Perhaps your system isn't recognizing the RAM.

If it is, then have you tried restarting MRTG?

The current script maintainer has kinda not been here for about a month.
I've got a few new configs lined up for new versions (already pm'ed him about it more than a month ago or something).
If/when I get time, I'll set up a new howto with updated stuff on my wiki, if anyone is interested.

That MySQL monitor looks nice ;).
Furthermore I have scripts lined up for:
1. Exiscan
2. SpamBlocker
3. CPU temp (mbmon & sensors :))
4. Apache usage in hits/hour

However I need time to script an installation interface for it, as the sysadmin now has to do a few things and choose a few things.

If you guys are interested, I can try to make a script for it, but I can't say when it's done, got a lot to do here...
