In this recipe we will see how to acknowledge triggers when they happen. Why do you need to know? To save others the frustration of looking into a problem that has already been resolved by you.
To be able to acknowledge some triggers, you need a complete functional Zabbix installation. To acknowledge some trigger, you need a failure on one of the triggers. If no trigger is in alarm then you could try for example, to increase the CPU load or stop the service from the Zabbix client.
When we go in Zabbix to our web interface, we have a list with the last 20 issues. As you can see, we have multiple columns with one being the Last change.
So how does it work? Based on our items that we have created and the triggers that were set on those items, an event will be generated in Zabbix. Those events are used to create actions but those events can also be acknowledged to notify other users that we have fixed the problem or that we are busy with the problem. This we can write down in our message box.
Acknowledgments can be done from the front page from the 20 Last item box or we can go in the Zabbix menu to Monitoring | Events and acknowledge the status of our item.
