Clearing Issues / Triggers / Events

[me2017]

I'd like to clear any ACKed triggers. This one seems stuck. The 'last change' was from 10/23/2016. How can I get rid of this?

I've attached an image here to better illustrate. What's even more interesting about this is that http IS running on both hhosts noted and /etc/passwd was changed at some point yesterday when doing testing. This wasn't noted by zabbix until the system was rebooted.

Hello!

Please, do the following only at your own risk!
First, find the pesky trigger you want removed:

SELECT * FROM zabbix.triggers WHERE value=1 ORDER BY triggerid DESC;

Then, withing the found results search for the required entry and change the "value" column contents for the specified trigger from "1" to "0". Save and check the trigger section, if it is still up and running.
If the offered way does not work, it may be a good idea to revert the change back to "1" value and search for alternative ways.
