Nagios Support Forum

These both look normal.

I am sure you have tried this, but if you send a regular email to this list is it duplicated?

The reason I ask, is that you have already shown that nagios is only sending one notification in the log... Can you verify on the listserv the received emails?

Thanks.

Regularv emails are not dupliacted - they are only sent once. This behaviour is very odd. I am wondering if I will need to do a database repair.

The reason I say this is that the issue only happens to a few hosts. There are hosts that have multiple notification groups and still report in the correct manner. I really don't know where else to look.

It certainly wouldn't hurt...

you can run

Hi,

I have ran the database repair and the additional command that you specified with the results below:

VACUUM
VACUUM
VACUUM

Unfortunately, it has not made a difference. We are still receiving multiple alerts for "some" services.

Is it the same few hosts? Are the notifications absolutely identical?

I'm wondering if we don't somehow have these hosts duplicated.

Thanks.

I am starting to see more hosts exhibiting the same behaviuor. We monitor over 8300 services so it is getting a bit frustrating.

I have manually checked the files and there is no duplication anywhere.

The issue also can be very random. In the attached, you can see an alert at 4:27 sent twice whilst the alert at 4:47 for the same service(in purple) is sent only once. Not sure how to explain this.

Any ideas?

I have a feeling this could be caused by duplicate versions of a cronjob running in parrallel

Can you run the following Not sure if we can catch it happening, but worth a try...

Thanks.
