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
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.

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

Hi,
really I'm not sure that this should work currently, because this limits fetched from DB returns as "" (empty string).
:D
I will do additional tests with this conditions, but I think for this case also possible use:
sensor_limit ne
(yes, also without last value)

I have update to r10228. Update & test my check with ANY conditions : sensor_value ge @sensor_warn sensor_warn notnull I no longer have an error with the null value. Need testing if alerting working when warm value is triggered. But I'm very perplexed about detail of entity checked :
[image: image.png]
I don't know why value is empty and why test on sensor_limit (notnull) is not displayed. FYI sensor_limit_warm existing in database : [image: image.png]
