Trigger problem: Server XXX does not answer to ICMP ping since 5 minutes

[joergi]

Hello,

we have a problem with the trigger.
We are immediately receiving the alerts “..does not respond to ICMP ping since 5mins” when the ping goes down.

Trigger expression:

{tmpl ICMP Ping:icmpping[,2,1001,,4000].last(300)}#1 | {tmpl ICMP Ping:icmpping[,2,1001,,4000].nodata(300)}=1

2014.09.04 07:37:33 - Server XXXX does not answer to ICMP ping since 5 minutes: OK
2014.09.04 07:36:33 - Server XXXX does not answer to ICMP ping since 5 minutes: PROBLEM

Attached you will find the ping graph....
Something is wrong in the expression and I don't see the problem. Many thanks for your help.

Regards,
Jörg
