When using NT authentication we are seeing a delayed alarm when the page is not available. The page down alarm seems to be preceded by this alarm.
When we get a 500 or 404 can an alarm be opened without delay?
Delay or re-try alarm
[SharePoint UAT Test] is already running
URL response for 'SharePoint UAT Test' failed. 12002 The request has timed out.
We do not see this behavior in non NT authentication checks.
- url_response configuration setting ->Retries before failure
Component : UIM - URL_RESPONSE
Monitoring interval was set to 180 seconds (3 minutes) and Retries before failure was set to 1 so it was taking about 4 minutes to see the alarm appear. 3 minutes + 1 minute (based on the retry setting).
Once we set the retries to 0, the alarm was received on time as expected.
Retries before failure:
Specifies the number of attempts to access the URL before reporting it as a failure. These retries are executed within a single check interval. For example, if the Check interval is set to 300 seconds and Retries before failure is set to 3, then, the probe executes all the 3 retries in 300 seconds and generates an alarm, on failure.
