Changing expression variable AGENT.NODATA.TIMEOUT

[KryzBell]

Hi All

I'm about 15 hours into learning and deploying a 200 host 4.4 system. I'm generally getting the hang of things, but I've reached a dead end that my google fu hasn't helped me resolve.

All my agents are active, and I want to be alerted if a system goes offline for more than x minutes. Where x is < the system default of 30.

I'm using the template "OS Linux by Zabbix Agent Active", which has a trigger named "Zabbix agent is not available (or nodata for {$AGENT.NODATA_TIMEOUT})"

This works to generate the alerts I want, but the default for the timeout is 30 minutes. I want to be able to manipulate that time which is where my current expertise runs out.

I'd like to either :

1. Locate and adjust the system variable behind $AGENT.NODATA_TIMEOUT to reduce it to 5 minutes,
2. Or, edit the expression to use 5 minutes as a fixed variable.

I'm unable to figure out the location or syntax of either.

The expression is

{Template OS Linux by Zabbix agent active:agent.ping.nodata({$AGENT.NODATA_TIMEOUT})} =1

Pointers and guidance would be gratefully received.

$AGENT.NODATA_TIMEOUT - this is a macro (variable) that can be defined by the user at various levels. You can view or change it. Read this for more information https://www.zabbix.com/documentation...ros/usermacros

That was the direction I needed. Thank you!
