Monitoring Squid with Cacti (Template Cacti for Squid... Complete...!!!)

I assume that you have installed snmp, squid and cacti, before. I will not explain again about how to install squid, snmp, cacti, etc.. there's so many article to discuss about that’s.
Then, if all installation is complete, let's make graph template for squid.

1. cek your squid configuration,
# squid -v
Squid Cache: Version 3.1.22
configure options:  '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/sbin' '--sbindir=/usr/sbin' '--sysconfdir=/etc/squid' '--datadir=/usr/share/squid' '--includedir=/usr/include' '--libdir=/usr/lib' '--libexecdir=/usr/lib/squid' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--x-includes=/usr/include' '--x-libraries=/usr/lib' '--enable-shared=yes' '--enable-static=no' '--enable-carp' '--enable-storeio=aufs,ufs' '--enable-removal-policies=heap,lru' '--enable-icmp' '--disable-delay-pools' '--disable-esi' '--enable-icap-client' '--enable-useragent-log' '--enable-referer-log' '--disable-wccp' '--enable-wccpv2' '--disable-kill-parent-hack' '--enable-snmp' '--enable-cachemgr-hostname=localhost' '--enable-arp-acl' '--disable-htcp' '--disable-forw-via-db' '--disable-follow-x-forwarded-for' '--enable-cache-digests' '--disable-poll' '--enable-epoll' '--enable-linux-netfilter' '--disable-ident-lookups' '--enable-default-hostsfile=/etc/hosts' '--with-default-user=squid' '--with-large-files' '--enable-mit=/usr' '--with-logdir=/var/log/squid' '--enable-http-violations' '--enable-zph-qos' '--with-filedescriptors=65536' '--enable-gnuregex' '--enable-async-io=64' '--with-aufs-threads=64' '--with-pthreads' '--with-aio' '--enable-default-err-languages=English' '--enable-err-languages=English' '--disable-hostname-checks' '--enable-underscores' --with-squid=/usr/local/squid-3.1.22 --enable-ltdl-convenience

If there’s no option '--enable snmp', you must reconfigure squid.

2.   Cek file /etc/squid/squid.conf
 Squid.conf usually located at /etc/squid/.  Make sure, some line below is exist.

acl bamboe src 192.168.3.0/24
acl snmppublic snmp_community public
snmp_port 3401
snmp_access allow snmppublic bamboe
snmp_access deny all

3. Test your snmp with snmpwalk
Command :snmpwalk  communitystring -v1 hostname:3401 .1.3.6.1.4.1.3495.1.1
for example, in my case,

snmpwalk -c public -v1 192.168.3.1

4. Add one line below to file /etc/snmp/snmpd.conf
proxy -v1 -c your_community_string hostname:3401 .1.3.6.1.4.1.3495.1
for example, in my case,

proxy -v1 -c public 192.168.3.1:3401 .1.3.6.1.4.1.3495.1

5. Download template cacti

It was not me who made it. Thanks to the person who first made the script template. :)

6. Configure Cacti

• Open Cacti and login as admin. Click Console > Import Templates.

• In page Import templates,  Click Browse/Telusuri. Find the file template that you downloaded earlier. Then click import.

• Now you will be back to page console. Click Console > Devices > Add.

 

• In page Device[New]. Fill the blank rectanguler in accordance with the your computer (squid). Then click Create, at the right bottom.

• Console > Device > [Name Device that you have created]

• Click Add Graph Template, find graph that you want, and click Add

 

• You will be back again to console. Console > New Graph. Find the host proxy squid. Then check graph template name that you want to create. And then, click Create, at the right bottom.

 

• Done. Let's take a look at the chart by clicking Graph. Wait 5 - 10 minutes, till you see the graph. There's so many button setting to view the graph, you can explore that's all by yourself.
