Large no. of invalid alerts for 'agent.ping' item

[unnikrishnan]

HI Team,

I'm using the key 'agent.ping' in order to monitor the status of Zabbix agents. In the trigger I use the expression 'hostname.nodata(15m)}=1'. ie If the server didn't receive data for 15 mins, it would trigger notification.

However it's not working as expected. It's giving many invalid alerts. Ie Even if Zabbix server is able to connect to Zabbix agent, it's getting triggered.

Have anyone faced any such issue?

My Zabbix server version is v2.2.3

Regards
Unni

I'm not sure if it's correct or not, but in documentation I read that nodata() has a parameter in Seconds. No any words about "minutes, hours, etc"

In your case it has to be like

hostname.nodata(900)}=1

Did you check it?
