Monitoring a Squid web cache/proxyx

The following recipe/template uses the 'squidclient' shell program to gather information about a running Squid web cache/proxy. So make sure that you get statistical data when running:

• squidclient mgr:info

On the server running Squid you will need to run the Zabbix agent and add these lines to the /etc/zabbix/zabbix_agentd.conf:

# Squid
