MRTG?

Tue Jul 31, 2012 6:24 pm

Hi all,

Simple question: anyone managed to get MRTG to work?

I have used "sudo apt-get install mrtg snmpd" and everything appeared to work. However when I run "cfgmaker [email protected] > /etc/mrtg.cfg" I get the following:

Code: Select all

And then "indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html" I get:

I have installed apache and php5 and they both appear to work.

Any suggestions?

Thanks.
Pete.

My useless suggestion is to use rrdtool instead of mrtg. It is written by the same guy, but rrdtool was created to overcome the limitations of mrtg.

The interface to rrdtool is generic, you only need to be able to create shell/perl/python scripts to provide current values on a period basis.

Take a look - http://oss.oetiker.ch/rrdtool/gallery/index.en.html

I don't really need it on my pi but I have played with it for a few years. Maybe i'll give it a shot after I move my root fs to my external usb drive.

I was thinking about buying a Pi just for network monitoring. I'm not entirely certain it has the umph to do the job.

sorry forgot to add the path of SNMP_Session.pm.

you can find it over here:
/usr/share/perl5/SNMP_Session.pm

found the solution somewhere in the bug section of ubuntu^^ there was one as well in the debian bug section, but that one didn't fixed the complete error, only a part of it.

I also got cacto install light night. pretty easy. apt-get cacti. I am running lighttpd. All I have have had to do manually so far is ass an alias in lighttpd.conf to the cacti site '/usr/share/cacti/site'.

Hey guys,

I recently installed mrtg in the same manner as the original post. I also have the perl module errors. However, my MRTG is working fine. You can check it out here: http://codycrew.net/mrtg

This is hosted on my Raspberry Pi running Apache and MRTG and that's about it. I do intend to research the PM errors and will probably try the patch suggested above.

I'm trying to achive a working result, but I'm stuck. What i've done so far;

Code: Select all

sudo apt-get install mrtg snmpd
After that i'm tring to create to config:

Code: Select all

[email protected] / $ cfgmaker [email protected] > /etc/mrtg.cfg
--base: Get Device Info on [email protected]:
--base: Vendor Id: Unknown Vendor - 1.3.6.1.4.1.8072.3.2.10

--base: Get Interface Info
--base: Walking ifIndex
--base: Walking ifType
--base: Walking ifAdminStatus
--base: Walking ifOperStatus
--base: Walking ifMtu
--base: Walking ifSpeed
This looks allright, but the /etc/mrtg.cfg has no information about the snmpd server/port? I assume this should?

Hey Pete,

Just some observations from my experiences thus far with SNMPD on my RPi that I poll using Cacti....(while you figure out that patch as it looks like it would work for you too)

Everything was fine using the default snmpd.conf file as the agentadress is set to:
agentAddress udp:127.0.0.1:161

Once I changed the config as I have many times before on Ubuntu machines it broke. When I uncommented the line:

agentAddress udp:161,udp6:[::1]:161

SNMPD failed to start and /var/log/daemon.log showed various errors regarding ipv6:

Aug 16 10:26:47 raspberrypi snmpd[4234]: could not open /proc/net/if_inet6
Aug 16 10:26:47 raspberrypi snmpd[4234]: payload OID: prNames

Aug 16 10:26:47 raspberrypi snmpd[4234]: /etc/snmp/snmpd.conf: line 143: Error: unknown monitor OID
Aug 16 10:26:47 raspberrypi snmpd[4234]: payload OID: memErrorName

etc etc etc....

with it eventually ending in:

raspberrypi snmpd[4234]: Server Exiting with code 1

netstat -l confirmed no snmp port listening

Anyway, long story longer, i have no use for anything ipv6 in the shortterm so i changed the agent address to :

agentAddress udp:161

sudo service snmpd restart

and voila shes cooking again......


I don't use MTRG but it appears the errors you are getting are also related to ipv6 specific lines of code.....so maybe have a look at your /etc/snmp/snmp.conf file and check out the agent address you have set....

Thanks for the reply n00badmin. Will try modifying the snmpd config file as suggested and post back the results.

Hey everybody,

I wrote a tutorial, too. For all german speaking people: http://kopfkino.irosaurus.com/tutorial- ... an-wheezy/

for all others: I think you can get it if you use google translator, that should work for you :D
http://translate.google.com/translate?h ... ian-wheezy

I also explained how to fix that annoying perl bug.

Hi all:

I made a one liner to fix this issue

Code: Select all

sed -i 's|import\ Socket6;|Socket6->import\(qw\(inet_pton\ getaddrinfo\)\);|' /usr/share/perl5/SNMP_Session.pm

loonix, your fix worked for me fine, thank you. MRTG is now working fine on my Raspbian, at least for load average. I'll try and add other stats data soon.

The problem with mrtg does have to do with support of ipv6 for snmp libraries used in mrtg.
Here are two pages which can help you with that:
1)http://oss.oetiker.ch/mrtg-trac/ticket/134
2) http://tasos.pavta.com/myblog/2012/06/1 ... redefined/
I will check the sed oneliner to see if it's the same thing. Thank you for that.
About the rrdtool and mrtg, they are not for the same thing. Mrtg does more than graph data (collect, store, graph). You can replace any part of that with your own tool, it's still mrtg. If you want to take a deeper look in how mrtg could work with rrd (storing the data in rrd format and no creation of png files except on demand) you could take a look at Steve Shipway's book and relative software, check here:
http://www.steveshipway.org/software/.
Tobi has promised a long time ago that mrtg v3 will work with rrd but I guess it's not time yet.

Wow ... that worked! (With sudo added before the sed)

Thank you.
