Stale hosts/items (freshness checking)

[sdwilders]

I make extensive use of active agents - relying on agents to send data back to Zabbix. I have used Nagios in the past and one nice feature was the ability to have a script run if no data had been received for a set period - known as freshness checking.

So, for example, I had it set to warn if a server hadn't reported back in 10 minutes, and if a workstation/laptop hadn't reported back in 2 weeks.

Is there a way to achieve this same behaviour in Zabbix?

I too want to know of such a feature.

Is it there?

trigger nodata(X) will wait X seconds before send an alert

Fantastic, thank you. Classic case of RTFM.

I added the following Item:
TemplateName:Host uptime (in sec)

and this trigger:
{TemplateName:system.uptime. nodata( 900 ) }

The agents report back every 5 minutes so the above triggers if nothing is received after 15 minutes. Works beautifully.
