Service Maps in Dev resetting after midnight – how to identify root cause?

[sadif_raja]

Hi Community,

We’re facing an issue in our Dev instance where Service Maps are being reset after midnight.

• Every morning, the maps created the previous day are gone.

• This started happening only a few days ago.

• I already checked Scheduled Jobs, Discovery Schedules, and Business Rules — nothing is running at that time.

• I also tried looking at sys_audit and syslog around midnight, but no clear deletes/updates were logged.

Questions:

1. Has anyone seen Service Maps being wiped/reset automatically in Dev before?

2. Could this be related to an instance refresh or cleanup policy?

3. Is there any specific Service Mapping setting, job, or plugin update that can cause this behavior?

4. What’s the best way to trace which process is deleting/resetting maps at midnight?

Any insights or pointers would be really helpful.

Thanks!

Are these are manually created map?

Are you able to discover the devices?

The relations are present on devices?
