This short reference guide was made on request by a creature called 'Humans' living on planet earth ;)
☻
This is a short reference guide to monitor SQUID various counters with the MRTG installed on Ubuntu. In this example I have configured SQUID and MRTG on same Ubuntu box.
Also I ahve showed howto install Apache, mrtg, scheduler to run after every 5 minutes, snmp services and its utilities, along with mibs.
If you have Freshly installed UBUNTU , You need to install Web Server (apache2)
apt-get install apache2
Now we will install MRTG
apt-get install mrtg
(Choose Yes to continue)
Now we will install SNMP Server and other SNMP utilities so that web can collect information for locahost and remote pcs via snmp.
apt-get install snmp snmpd
Now set your community string in /etc/snmp/snmpd.conf , Remove all Lines and add the following line only.
rocommunity public syslocation "Karachi NOC, Paksitan" syscontact aacable@hotmail.com
Save and exit.
now edit /etc/default/snmpd
and change following
# snmpd options (use syslog, close stdin/out/err). SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid' To THIS: # snmpd options (use syslog, close stdin/out/err). #SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid ' SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf'\
and restart snmpd
/etc/init.d/snmpd restart OR service snmpd restart
Now install MIB down loader,
sudo apt-get install snmp-mibs-downloader
Now copy all mibs in any single folder like /cfg/mibs/
mkdir /cfg mkdir /cfg/mibs cp /var/lib/mibs/ietf/* /cfg/mibs cd /cfg/mibs wget http://wifismartzone.com/files/linux_related/squid.mib
MIBS are required if you want to use OID names instead of numeric values :D This was the issue for which I was stuck for many hours :(
Format that will be used in cfg file
E.g:
LoadMIBs: /cfg/mibs/squid.mib
↓
Testing SNMP Service for localhost.
Now snmp service have been installed, its better to do a snmpwalk test from localhost or another remote host to verify our new configuration is responding correctly. issue the following command from localhost terminal.
snmpwalk -v 1 -c public 127.0.0.1
and you will see lot of oids and information which confirms that snmp service is installed and responding OK.
As showed in the image below …
.

.
.
Adding MRTG to crontab to run after very 5 minutes
To add the schduler job, first edit crontab file
crontab -e
(if it asks for prefered text editor, go with nano, its much easier)
now add following line
*/5 * * * * env LANG=C mrtg /etc/mrtg.cfg --logging /var/log/mrtg.log
Some tips for INDEX MAKER and running MRTG manually …
Following is the command to create CFG file for remote pc.
cfgmaker public@192.168.2.1 > /cfg/proxy.cfg
Following is the command to check remote pc snmp info
snmpwalk -v 1 -c public /cfg/192.168.2.1
Following is the command to create index page for your cfg file.
indexmaker /etc/mrtg.cfg –output /var/www/mrtg/index.html –columns=1 -compact
Following is the command to stat MRTG to create your graph file manual. You haev to run this file after every 5 minutes in order to create graphs.
env LANG=C mrtg /etc/mrtg.cfg
.
.
.
Now LETS start with SQUID config…
SQUID CONFIGURATION FOR SNMP
Edit your squid.conf and add the following
acl snmppublic snmp_community public snmp_port 3401 snmp_access allow snmppublic all
SAVE and EXIT.
Now use following proxy.cfg for the squid graphs
.
.
proxy.cfg

.
Then issue following command. To get graph from new file, you ahve to run the command 3 times.
env LANG=C mrtg /etc/mrtg.cfg
then create its index file so all graphs can be accesses via single index file
indexmaker /etc/mrtg.cfg –output /var/www/mrtg/index.html –columns=1 -compact
Now browse to your mrtg folder via browser
and you will see your graphs in action. however it will take some time to get the data as MRTG updates its counters after very 5 minutes.
.
