Trigger does not send an Email when its okay

[miramira007]

Hellau together,

i have a problem with following issue:

i set the trigger:
a=0 and b=0

it sends me message when a and b equal 0 with an error message

But i want, that the system sends me an email too, when its ok again.

logical is (true table mathematical table used in logic)
a = true and b =true ==> true

the negation is:

a = true or b = true ==> true


So i expect an okay message from zabbix server, when one of a or b is equal 1.


Is there some bug in the system? Or haven't i configurated something wrong??

{IPx:icmpping[IPx].sum(#10)}=0 and {IPy:icmpping[IPy].sum(#10)}=0

My issue is:

if one of them is not reachable, it isn't a problem. But if both not reachable so it is a critical issue. But i want to know if is one of them reachable again.

I hope i give an right explanation.

CU,
mira

I'm not sure whether I've understood correctly.

How about using the Recovery message option of Actions, don't using the Action condition Trigger value = PROBLEM or to create a dedicated Trigger that fires on the opposite?

[miramira007]

I created an Action. The sytem is sending an email to me, when a=0 and b=0. I configured an action to, when the "trigger value = OK", So i expect an email with a OK, too. When one of "a or b = 1" again.

Mathematical correct is:
A => a=1 ∧ b=1 ==> true
!A => a=1 ∨ b=1 ==> true


What should I do? How can i set a Trigger if its OK again?
