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.

Subject: [Observium] Alert : Matching "null" value in condition?

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
