Alex,
I have a test that is sending alerts but I cannot find the test to delete it. I don't know the name of the test, but I get the alerts for this test, so I know it is running.
1) I searched for the test by test ID and could not find it. I DID find the testID by looking in the MainLog but that testID is missing. I even sorted all tests by TestID and that ID was missing.
This is from the mainlog:
[8/8/2016 12:42:00 PM] HTTP: /HTTPSMSXX Host is alive 172 ms HTTP test (sms3.mblox.com) 26563
2) I search within Hostmonitor and I also exported all tests and tried to search for it that way, but I cannot find it.
