Please help with the answer to the question on the mechanisms and logic of closing the Problem for events related to unavailability of synthetic tests.
I looked at the documentation and didn't find a description of our question.https://www.dynatrace.com/support/help/shortlink/synthetic-alerting
There are a number of synthetic tests set up.
as parameter Outage handling - the following parameter is set
Next, we receive events about the test unavailability. And the problem opens
In the following figure, we see two test fail events
Between the tests, we see two successful tests. Time between unsuccessful tests 15 minutes
Dynatrace does not close the problem at 03:17 - after the first successful test, but for some reason closed it at 03:32
we do not understand the mechanism of closing the problem.
Plus we have a task to send an escalating notification if the problem has been open for a long time, but with such an incorrect lifetime of the problem, we will receive erroneous escalations
Solved! Go to Solution.
It might be that Dynatrace is hanging onto the problem to ensure the issue doesn't arise again, other wise you might get an alert for a failure, then closure, then failure, then closure. we see this with purepath failures as well, where Dynatrace AI will keep a problem open for 10-15mins after the last failure is detected.
