During a Scheduled Maintenance, test results are no longer polled and alerts should also be suspended. If you receive an alert for a suspended device during the Maintenance window, please confirm the below. If this does not help resolve the issue, please create a new support ticket attaching all of the below:
a) Audit.log (On the BVE <TraverseHome>\logs\webapp\audit.log)
Confirm that the Maintenance Window was created and finished.
b) Scheduled Maintenance Start email
Confirm that all the expected devices are listed and the start time is correct.
c) Scheduled Maintenance Finished email
Confirm that the end time is correct.
d) The test alert email you unexpectedly received
Confirm that the device for this test is included in the Scheduled Maintenance
e) Screenshot of the Action Profile assigned to that test
f) Screenshot of the Scheduled Maintenance configuration
g) Action.log (On the DGE <TraverseHome>\logs\monitor\action.log)
h) Run a Threshold Violation report for the test covering the time span of the Scheduled Maintenance
If the device was properly suspended, all results for the Scheduled Maintenance period should also be suspended. Polling should resume after the Maintenance is complete. If the results weren't suspended, then the device was never properly suspended in the first place.
