Had a situation where I (and very high ranking individuals) were paged about a critical situation that did not exist. An alert has been setup up to page out if a certain OID comes back larger than 30. It is essentially always 0.
In this instance, the poll was missed, so there was no data. At that moment, the alert triggered, meaning that the alert must have been evaluated as true. Thus, the alert engine must have used something that was larger than 30 during the evaluation. Clearly it shouldn't, and I believe it is supposed to use the last valid polled information.
Has anyone seen this before? Can anyone think of a way avoid it? I honestly just think it is a bug, but seems like something that folks should have run into before. Support was no helpful. At all.
