HOWTO: Install MRTG (FULLY AUTOMATED)

jlandes said:
I believe you all need to at least run MRTG once before the HTML files will be created. To do that, SSH into your box as root and execute the following command:

Code: 
env LANG=C /usr/local/mrtg-2/bin/mrtg /var/www/html/mrtg/core/mrtg.cfg

Do this at least twice, because the first time you might get some errors. Also, there is a line in your /etc/crontab file that needs to be altered. When this script is installed, it adds the following line to your crontab file:

Code: 
*/5 * * * * root /usr/local/mrtg-2/bin/mrtg /var/www/html/mrtg/core/mrtg.cfg

That needs to be changed to this:

Code: 
*/5 * * * * root env LANG=C /usr/local/mrtg-2/bin/mrtg /var/www/html/mrtg/core/mrtg.cfg

I hope this solves the problems you are having with getting MRTG to work.

Got it working on CentOS 4.4 64bit after doing the above hehe :D

not sure if its plotting the grpahs correcetly though i'll wait 24 hours and see.

I dont need any ports setup for this do I as im using a firewall other than the standard web server stuff correct?
 
next question is how do I get mrtg monitoring mutltiple servers? do I have to have apache/php etc on each server?

Nice work guys... I've added the changes to mine... even learnt a few commands in the process... but not getting any data appear for the extra sections.

99.9% sure I've entered them correctly.

Could it be some firewall ports i need to open in APF at all?

I'll post a link once i have this sorted :)

Nath,

Remove the DOT between mail and log. Becouse bij a default install from CentOS there wont be a file "mail.log" so it has to be "maillog".

Code: 
if [ "$TYPE" = "sa" ]; then
    INDATA=`cat /var/log/maillog | grep "spamd: connection" | wc -l`
    OUTDATA=$INDATA
fi

Or download them conplete:
http://sv03.aklmedia.nl/filedump/system
http://sv03.aklmedia.nl/filedump/mrtg.cfg

Don't forget to chmod `system`. It should be executable (-rwxrwxrwx 1 root root 2020 Jul 27 23:58 system)

Addition: people who use debian has to use mail.log in stead of maillog :p
 
Thx Randy... the . was indeed preventing the SA scans from displaying ;)

tho I'm not convinced about the IMAP / POP3 logins and Email Delivered graphs being correct.

Email Spam Blocked is very much quiet too - which is odd, unless it depended on the SA Scan's section working.

If its ok, I will PM you with the link to the live graphs if you want a look randy. You might spot something from the output that I've missed.

Cheers guys.

Nath,

I reather prefer direct mail (or MSN); [email protected].
 
Thank you very much, it looks very convenient. That's a great work

However, I have the same problem. My company networks have many servers and I use one server to monitor others. How do I use this to monitor multiple server?

Thanks

quyenlt and flumps,

The default installation can't know your network details; you'll have to configure MRTG and make sure the necessary ports are open for snmp monitoring.

There's a fairly decent Mini How-To here.

(I just have our lead RHCE tech take care of it for me ;) ).

But adding that to the config file means your network stats for the other servers are added, but if you like stats for the cpu/mem/processes/etc for the other servers it is another story?
 
Yes, then you have to install helper apps (I think that's what MRTG calls them) to each specific server.

We don't do it that way; we have each of our servers email us it's own statistics information.

Within a few days i will be looking for a method to let 1 mrtg installation get the statistics from other servers as well, this part together with more stats will be released within some weeks by Imtek, Randy and me.

http://58.65.233.41/mrtg/ :(

same problem

i have the same problem with this installation mrtg

i have folder in /var/www/html/mrtg and i have only folder "core" with mrtg.cfg and *system

when I enter address my site in web browser like http://myadress/mrtg i see this


You don't have permission to access /mrtg/ on this server. ?

I try chmod 777 and still error.
 
Please see my post earlier in this thread about the requirement of running MRTG at least once to create the HTML files. You also need to modify the entry in your /etc/crontab file.

Has anyone been able to implement the 95 percentile option?

The Metered 95% MRTG stat is a moving average taken over the last 30 days, with the top 5% of the peak usage discarded.

http://www.ronny-goerner.de/patch/

Sean Adams doesn't support that patch anymore so you need to grab it from places where people have copies of the script.

If anyone has been able to implement it,. please let me know how to apply it.

The instructions that I found didn't make sense to me.

thanks,

-Alon.
 
I use collectd to obtain stats about my server... uses rrdtool and seems to produce many more stats to give you a better look/view of the servers status.

Do to it's plugin facility, it's easy to write additional plugins. :)

The original script of the install.mrtg.sh needs to be updated.

It is trying to d/l the mrtg.tar.gz file from an old location that has been moved away, so it is no longer working.

pico/nano/vim the install.mrtg.sh such that you change one line in it:

You need to modify the line inside it of the wget from:

wget http://people.ee.ethz.ch/~oetiker/webtools/mrtg/pub/mrtg.tar.gz

to

wget http://oss.oetiker.ch/mrtg/pub/mrtg.tar.gz
Click to expand...

Once that path is fixed, the rest is working fine.
