Trigger expression with a Regex Threshold?

[aurelie]

Hello all,

I'm trying to implement a trigger on a hardware status, with that numerical values status:
PROBLEM = unknown(1), ready(3), reset(4), down(6)
OK = running(2), runningAtFullSpeed(5), standby(7)

Is it possible to define a regex into the expression constant to avoid to repeat the expression for each status?

I tried several expressions but nothing seems to work:
{ZabbixServer:HardwareStatuskey.last(#1)} = @HardwareRegex
{ZabbixServer:HardwareStatuskey.last(#1)} = (1 or 3 or 4 or 6)
{ZabbixServer:HardwareStatuskey.last(#1)} = [1346]
{ZabbixServer:HardwareStatuskey.last(#1)} = {$callHardwareRegex}

Is someone have an idea?
Thanks

can you try:

{ZabbixServer:HardwareStatuskey.last()}=1 or {ZabbixServer:HardwareStatuskey.last()}=3 or {ZabbixServer:HardwareStatuskey.last()}=4 or {ZabbixServer:HardwareStatuskey.last()}=6

OR

{ZabbixServer:HardwareStatuskey.regexp(1|2|4|6)}=1

see

Hello Michael,

Thanks for answering.

But as metionned in Zabbix documentation, the function regexp() only supports String, Text and Log values, while in my case I have a numeric Item.

For the other solution :
{ZabbixServer:HardwareStatuskey.last()}=1 or {ZabbixServer:HardwareStatuskey.last()}=3 or {ZabbixServer:HardwareStatuskey.last()}=4 or {ZabbixServer:HardwareStatuskey.last()}=6

It works, but I was wondering for an easier way to write it, as I will also have to manage three occurrences before trigger status change.

If you or anyone have an other idea...
Thanks

I finally got it with Michael clue.

To be able to use numeric values with the regexp() function, I have to change the "Type of Information" of my Item by "Character" and I can write :

{ZabbixServer:HardwareStatuskey.regexp("1|3|4|6",# 1)} = 0
