zabbix 如何监控squid?

olga

　　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
  
• UserParameter=squid.http_requests,squidclient mgr:info|grep 'Number of HTTP requests received:'|cut -d':' -f2| tr -d ' \t'
