Trigger from string values by using regexp

[rutkowsky]

Hello everyone

I have a problem to create trigger from values as string (SNMP). String value (from QNAP device) is for example "39 C/98 F". I need "39" only to set up trigger let's say > 45 in order to send notification that temperature is too high.

Thank you in advance for your help.

A hackish work-around could be to use a trigger expression like this (not tested):
{<server>:<key>.regexp("^(-[0-9]+)|(^[0-9]|[1-3][0-9]|4[0-5]) C")}#1
