Communicating with the Zabbix API can be quite cumbersome, especially if you don't have a background as a programmer. For a sysadmin, it would be very nice if one could just run some CLI commands to control Zabbix behavior.
Wouldn't it be wonderful if you could fetch a list of active triggers and parse it with grep or sed to find the specific triggers you are looking for? Or perhaps you need a list of historic values that you can parse in a custom script? How about a cronjob that downloads and emails all the graphs in the system matching a certain regex?
In this presentation Raymond Kuiper will talk about some of these possibilities and show you how he achieved these things in his Zabbix setup.
