[BUG] The threshold rule cannot be triggered when the indicator value is "no data"

[rty813]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

As shown in the figure, when there is a value in the "Error Message" column, the "Value Exists" threshold rule can be triggered, but if the "Error Message" column is "No Data", the error threshold cannot be triggered anyway.

That is, the threshold rule I set is "contains(message, "Client")". When there is a value in the error message and it is the value in the screenshot, the threshold rule can be triggered normally. However, if the error message becomes "no data", no error will be reported and the error will not be eliminated.

Expected Behavior

When the indicator value is "no data", the alarm recovery should be triggered. Or the "!exists" threshold should be triggered.

Steps To Reproduce

try alarm threshold rule: no value exists

This is how I set it now. However, when the "error message" is "no data", it will not trigger an alarm.
