Retry Check

[mattsmith]

Hi All,

I'm new to Zabbix and am currently in the process of migrating from Nagios, I have a quick question. In Nagios you can set a retry check interval and a number of check attempts.

Example you could try and ping ServerA if ServerA didn't respond the check attempt would be incremented by one, a retry check interval would then kick in for example 30 seconds. After this interval ServerA would be checked again. if this check failed 3 times a notification is sent. Is this possible with zabbix?

Is this set in the trigger or the action, possibly the esculation part?

I have also read the post below, this is exactly what i am looking for

Many Thanks

that is not currently supported in zabbix - and given the flexibility of trigger expressions, it might not even be such a great feature

on the other hand, it might be possible to recreate with actions + api callbacks, but that might be a bit hackish then

Hi,

Firstly thanks for your quick response.

I completely agree trigger expressions are very flexible. All that I am after is a trigger that will check the value of the last 3 ping response times and if all 3 are greater than 500ms change state/alert.

Do you think that this is possible with the current selection of triggers?

min(#3)>500 or similar.
see http://www.zabbix.com/documentation/...gger_functions for more detail

Cool, that's what im looking for.

Can you confirm that this would check the last 3 values for being over 500ms or would i need to add some &'s in.

i.e
min(#3)>500&min(#2)>500&min(#1)>500

Thanks

min(#3)>500 should suffice - if you look at the manual, that's minimum from the last 3 values. of course, make sure to use correct trigger syntax with host & item reference etc

That's working a treat, thanks for your help.

Are you able to assist with a problem that I have with getting an external script working with zabbix?

The output of my script is as below, this has an exit status of 3

Error: value "blah blah" not found | 2

The number 2 is the time in seconds that the script took to execute. (this needs to be graph-able)

This script also has a exit status of 3 (previously used by nagios) to flag up the error state

and the text "Error... " was then used as the error message.

Is it possible to use this output with zabbix? or will i need to create separate triggers for each element? Nagios used the | symbol as its delimiter to separate the graphing data.

Many Thanks
Matt

it's best to start a new thread with a new question, otherwise it all becomes a bit too messy and hard to follow
