I have created an alarm condition like this to raise: fabs([th0temp-age:999]-[thb0temp-age:999]) >= 100 (don't ask why), and the corresponding condition for clearing the alarm is: fabs([th0temp-age:999]-[thb0temp-age:999]) <= 3

When I go to the "Services" tab and hover over the orange "i" box I see that most recent evaluations. An example is attached.

Now during the interval covered by this log, the raise condition never is/becomes true, and the clear condition always is true. Yet, sometimes, there is a log line with the raise condition in it, evaluating to false. So the alarm is not actually raised, but the line should not appear, I think, and it surely does not appear every single time. So when is it supposed to appear. I would expect either every evaluation, or only when it evaluates to true.

That, I suspect, is a bug. It does not affect the functioning of the alarms, but makes looking at the log a little harder than strictly necessary.

From the log I can see that raise condition is not as you said. I can see a second expression to be evaluated. Are you doing the brackets right? Please post the correct raise condition.

The full raise condition: I simply left the second part out as it does not seem relevant, but there it is. The log shows that overall raise condition to evaluate to false.

The idea of this log is to tell you about all evaluations done. Stripping unsuccessful raise or clear computations would contradict the idea to trouble shoot false formulated conditions.

I understand that, but it does not seem to show all evaluations, or at least the raise condition is not evaluated as often as the clear condition. Why?
