Provide UUID for system id

Description

Background
Folow up ticket from https://opennms.atlassian.net/browse/NMS-14684#icft=NMS-14684

OpenNMS has a system id, stored in the table monitoringSystems.
It is accessed via DistPollerDaoHibernate.whoami() and exposed via OIA: RuntimeInfo.getSystemId()

Historically the id was always 00000000-0000-0000-0000-000000000000. With https://github.com/OpenNMS/opennms/pull/5216 we allowed to use any UUID. It can now manually be set via:

Update monitoringsystems set id=gen_random_uuid () where id = '00000000-0000-0000-0000-000000000000' AND type='OpenNMS' AND location='Default'

Goal

  • Going forward we want any new install of OpenNMS to have a unique system id.

  • Nice to have: a manual? migration path (e.g. description?) for existing systems that want to change their current system id to a UUID.

Business Reason
Within TSAAS we use the system id for logging. It will be easier for customers to interpret the logs.

Have we followed up on the other system ID location? I think we should make both the same value unless there is a good reason to have separate ones. Or can we remove the second location and use a single source?

Merged into release-30.x

There seems to be a completely separate system id that is maintained in org.opennms.features.datachoices.internal.StateManager, which is also included in the usage statistics report payload. Worth following up on once this is merged in.

From my testing, the command listed above won't work on its own since the alarms table has a foreign key restraint on that id. It's straightforward to modify that constraint to cascade the updates, see the additions here:
