TODO: Actually found a bug in original implementation. There is an inconsistency in the way AlertAfter is treated.
|
|
For "First alert only" (ie. AlertEvery=0), it is the number of failures to ignore before alerting, so AlertAfter=1
|
|
will ignore the first failure and alert on the second failure
|
|
For other intervals (ie. AlertEvery=1), it is essentially indexed on one. Essentially making AlertAfter=1 trigger
|
|
on the first failure.
|
|
|
|
For usabilty, this should be consistent. Consistent with what though? minitor-py? Or itself? Dun dun duuuunnnnn!
