Hi all,
Thank you for adding this option ☺ We also had some false positives due this missing function. I changed some alerts now and it’s working fine so far.
Example test condition (require all conditions): sensor_value ge @sensor_limit sensor_value ne 0 sensor_limit notnull

Does “sensor_value notmatch“ work?
That’ll end up being ‘ if $sensor_value != “” ‘ or there abouts
I’ve just added “isnull” and “notnull” operators (last argument isn’t used), but you need to be running r10226 for that.

Hello,
In alerting, do you have the option to match "null" value? For example, to match/not match the sensor with sensor_limit_warm = null value.
My goal it's create alerting with "sensor_value gt @sensor_warn" but excluding when sensor_warm is "null" in database. Because that's create false positives.
Thanks!
Johann
