agent.ping - Value won't change from 1 if server / agent is down

[shlomia]

Hi, So I'm pretty new to Zabbix and what I'm trying to accomplish is to monitor a server using agent.ping key.
The values for that key are:
Returns nothing - unavailable; 1 - available
So when the server is up, The value is 1 and it's good.
But when the agent is down or the server is down, I'm getting PROBLEM on my trigger:
{Server:agent.ping.nodata(2m)}=1
which is good, But the value is still "1".
I expect the value to change to something another and show "Down" or "Unavailable", You get me?
This is the notification I get when a problem occures:

Problem started at 17:37:23 on 2020.07.13
Problem name: Ping Status
Host: Git
Severity: High
Value: Up (1)
Event ID: 174

As you can see, The value is Up (1) but the trigger reports problem! ( The value should be Down ).

Thanks!!

That may be more of a problem with the notification than with the trigger. What version of Zabbix are you running, and is this a new install or have you been using Zabbix for a while?

First, don't get confused by the "1" in the trigger itself. That's not the return from agent.ping, it's the "true" comparison value for the nodata() function (with an argument of 2m, for 2 minutes). You can read it as "agent.ping has returned no data for 2 minutes == true"

Regarding the message you're getting: find the Action that is matching / handling this event, and go to the Operations tab for the Action and show us the contents of the "Default message". If the default message is using "{ITEM.LASTVALUE}", read up on that macro.
