Trigger for IfOperStatus

[JayJay]

Hi,

I am hoping someone can help me create a trigger for IfOperStatus on a switch.

I want an email to send out if a port changes from "1 (UP)" to "2 (Down). Then a recovery message once it changes back to "1 (UP").

This way I will be able to monitor if a port is unplugged and send out a notification saying "Port X has been disconnect" and a recovery message of "Port X has been reconnected"

I also want the trigger (or possibly a separate trigger) to activate if a port changes from "2 (Down)" to "1 (UP)".

I cannot seem to find the right expression(s) on the trigger to achieve this.

I am running Zabbix 2.0.0RC2.

Any help would be much appreciated.

Hi,

I use the following expression to monitor if the IfOperStatus is different from IfAdminStatus.
I use this for linux devices, therefore you would need to modify it for your purposes.

{NetworkDevice:ifDescr.["{#SNMPINDEX}"].strlen(0)}<0|
({NetworkDevice:ifOperStatus.["{#SNMPINDEX}"].sum(#10)}#{NetworkDevice:ifAdminStatus.["{#SNMPINDEX}"].sum(#10)})

My trigger name looks like this:
Inteface ({ITEM.VALUE1}) Status changed on {HOSTNAME}

{ITEM.VALUE1} is the Value of expression NetworkDevice:ifDescr.["{#SNMPINDEX}"].strlen(0)}<0 which allows me to get the name of the affected interface.

The OIDs you are monitoring should be of type INTEGER, therefore you can just use numeric operators.

And: http://www.zabbix.com/documentation/...gers/functions

Hi Netmon,

Thank you very much for your quick response (and apologies for my lack of).

You gave me an idea with the comparison. I am think of using the following trigger to tell if something has been plugged into a port on a switch

{Template_Switch_Monitoring:ifOperStatus.1.last(#1 )}=1&{Template_Switch_Monitoring:ifOperStatus.1.la st(#2)}=2

Then the opposite if something has been unplugged.

{Template_Switch_Monitoring:ifOperStatus.1.last(#1 )}=2&{Template_Switch_Monitoring:ifOperStatus.1.la st(#2)}=1

I can then have a trigger for each of the above events.
I now just need to test this on an SNMP low level discovery.

Hi Jay,

On LLD that should also work.

Checkout github.com/simonkowallik/Zabbix-Addons if you should miss some discovery functionality within zabbix LLD. But if you use Cisco, you probably will be fine with Zabbix LLD. :-)
