Trigger for consistency of service

[cgasser]

Hi, I have a ICMP Ping item which does measurments every 15 seconds. If the last 3 pings are failing I get a message. That's fine. But I don't know how to add a trigger which fires if X% of the last 100 measurements have failed.
Reason is, in one site someone produced a curcuit by connecting one switch port directly with another port. Very stupid. But themonitoring was not able to catch that, as just about 20% of the PINGs were failing.

The math. I guess you have a item icmpping = 0 - ICMP ping fails, 1 - ICMP ping successful. Just sum last 100 value sum(#100) - and this sum is your success ping rate.
