Hello
The comments ban be related to:

• a simple comment on a resource
• a downtime
• an acknowlege

If you don’t want to keep them for a long time, I invite you to set a retention parameter in “Administration  >  Parameters  >  Options”.

Regards

I have 0 days on Retention duration for comments and Retention duration for downtimes.

I dont understand.

0 days means no purge

Ok thanks.

@ensenada just keep in mind that the purge sript will only delete the comments if the expiration date is old than the retention parameter.
It means it will never delete comments if they are still related to a current downtime/acknowledge

I understand.

I just wanna delete all comments older than a month and not related with an current downtime for example.

Thanks for help !
