How to defer zabbix notification?

[mazate]

Hi everyone,

Is there anyway to defer zabbix of sending its notification, such as an e-mail?

My network is oftenly unavailable for about a couple of seconds, and my e-mail account is flooded with zabbix notification e-mail.

So, I would like zabbix to send its notification only if the network is down for more than 3 minutes.

What should I use for my trigger expression.

Anyone please help...

Thank you very much,
mazate

Hi,
Why don't you post your trigger expression as it is configured now? Then people may comment on that.

Hi David,

Thank you very much for your reply.
Currently I'm using the default template for Windows,

{Template_Windows:status.last(0)}=2

by setting Update interval (in sec) = 180

Thank you in advance,

I've tried this expression but it still doesn't work...
({Template_Windows:status.last(#1)}=2)&({Template_ Windows:status.last(#2)}=2)

I've found example#7 in zabbix document and it should work... I'm trying it now.

It seems that the trigger in example#7 just counts the number of occurrence, not the duration of it...

What I think would match your config as it now stands is this:

{Template_Windows:status.count(180,2,"eq")}>0

Which counts the number of values equal to 2 in a 180 second window. If there are any occurences then the trigger will fire.

To make this work better reduce your polling interval to 60 and try this:


{Template_Windows:status.count(180,2,"eq")}>2

That, or something similar, should work.

Surprisingly, using this expression, the trigger hasn't fired any notification (even the network has been disconnected for more than 5 minutes).

What are you seeing in latest data?

[mazate]

It shows...

and in the Event tab, its status is OK with no Actions.

[Yello]

Can you post the trigger expression as it is configured now?

[mazate]

Pretty similar to what you advised,
Trigger Expression: {Template_Windows:status.count(240,2,"eq")}>2
I set the update interval to 60 seconds.

Strange. This trigger format works fine for me. Tell me more about how you're triggering. There may be another way of setting up the trigger. What values does the item return aside from 2?

[mazate]

I'm not sure if the update interval value can be set online.
I have changed this value from 120 to 60 seconds without restarting zabbix server.
