Count function not working as expected

[leonardomachado]

How to create a trigger this trigger?

1 - Check CPU avg5 (average 5 min)
2 - count if the last 3 returned values are greater then 5
3 - if count=3, event occurs

{myserver:system.cpu.load[,avg5].count(#3,5,'gt')}=3

Is it right?
I am receiving the following error message:

Evaluation failed for function: {myserver:system.cpu.load[,avg5].count(#3,5,'gt')}=3

Thank you.

that should work, assuming your item has at least 3 values - but why not use something simpler like min() or avg() ?

ok, changing triggers to use min and avg.
thnks.

Hello
Question is very old, but maybe I can help someone, now also faced with the problem that occurs, the function "count" return errors "Evaluation failed for function", the reason was quoted in the "count(#10,20,"gt")} = 10" after that took them as: "count(#10,20,gt)} = 10" all earned.
