Monitoring Squid With Cacti [Ubuntu Server 13.04]
What is cacti?
Cacti is a complete network graphing solution designed to harness the power of RRDTool‘s data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices.
What it will do?
It will generate graphs lots and lots of based on device types. We can add add various data sources templates and much more..
First we need to make some changes to our squid server so as to allow SNMP monitoring and graphing in Cacti.
1. Install the following:
sudo apt-get install snmp sudo apt-get install snmpd sudo apt-get install snmp-mibs-downloader
2. Comment out mibs: in /etc/snmp/snmp.conf like this:
# As the snmp packages come without MIB files due to license reasons, loading # of MIBs is disabled by default. If you added the MIBs you can reenable # loaging them by commenting out the following line. #mibs:
3. Add the following lines in /etc/snmp/snmpd.conf
proxy -v 1 -c public 127.0.0.1:3401 .126.96.36.199.4.1.3495.1 rocommunity public syslocation "Home" syscontact email@example.com
4. Add the following lines in /etc/squid3/squid.conf
snmp_port 3401 acl snmppublic snmp_community public snmp_access allow snmppublic all snmp_incoming_address 0.0.0.0 snmp_outgoing_address 255.255.255.255
5. Restart the services:
service snmpd restart service squid3 restart
6. Test SNMP Configuration by :
snmpwalk -v 1 -c public localhost .188.8.131.52.184.108.40.206.0
If everything’s right you will get following output:
SNMPv2-MIB::sysDescr.0 = STRING: Linux ubuntu 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:19:42 UTC 2013 i686
Cacti Server installation in Ubuntu Server 13.04
1. Install cacti:
apt-get install cacti
3. Go to your cacti console @ http://hostname/cacti
Default Username:Password = admin:admin
4. Login to the cacti console
5. Then we’ll install the template for squid from https://copy.com/o4CTmPUN4Z4eOH1x
6. Click Import Templates -> Browse for the templates -> Import
7 Go to Devices -> Add
8.Change the following:
Device : Give a description for your device.
Hostname : Put in Squid IP/HostnameTemplate : NLANR Squid Proxy
9. Then click on Create Graphs for this Host.
10. Select Graph Template Name which you want to generate -> Create
11. Goto Graph Trees -> Add -> Give a name -> Add Tree Item
12. Tree item type – host -> Select a host from the list -> Create
13. That’s it. Your graph will be generated and you can view it in the Graph tab.
