Sometimes triggers in Zabbix are too sensitive and you get notifications all the time because of quick repeated status changes; this is what we call flapping. This could be for example a swap file that is growing and shrinking all the time, making Zabbix send notifications that there is not enough free space left and a few seconds later going back in an OK state because there is enough space again to come back in alarm once again, a few seconds later. Another example of flapping could be the CPU load going over and under the threshold every x number of seconds. Let's see how we can solve this.
For this recipe, we only need a Zabbix server with an agent installed on the Zabbix server or some host and of course access with a super administrator account, like the one that comes standard with the installation.
