User macros with context can be used to accomplish more flexible thresholds in trigger expressions. Different thresholds may be defined on user macro level and then used in trigger constants depending on the discovered context. In this post we are going to check simple example, how to configure it in real life scenario.
Zabbix trigger expressions provide an incredibly flexible way of defining problem conditions. If you can express your problem using plain English or any other human language, there is a great chance it could be represented using triggers.
I’ve noticed that even experienced Zabbix users are not always aware of the true power of triggers. The article is about defining problems in a smart way so that all alerts generated by Zabbix will be about real issues. No flapping, no false alarms any more. Interested?
Often host level maintenance is too much. Picture a machine running multiple services: While one service has a scheduled downtime, others continue their work and you want to be alarmed about them. Zabbix has no maintenance on trigger level at present, but you can work around it quite easily.
