Description Yadnesh Kulkarni 2023-01-31 06:02:16 UTC

Description of problem:

Add a post upgrade action in documentation[1] to delete obsolete telemetry users.

While upgrading RHOSP13 to RHOSP16.2, legacy telemetry services(gnocchi, ceilometer, aodh) are removed during upgrade unless it's explicitly enabled.
These services are disabled by default in RHOSP16.2
```
source ~/overcloudrc

# Find which telemetry endpoints exist after upgrade.
openstack endpoint list | grep -i -e aodh -e gnocchi -e panko

# Delete the users of the missing endpoints.
openstack user delete aodh gnocchi panko
```

Performing this task is not mandatory, this is just a cleanup task. Existance those users with deleted endpoints doesn't impact the cloud in anyway.

25.2 Deleting users of disabled telemetry services

<blurb about telemetry services being disabled by default, this cleans up left over endpoints>

.Procedure

. Login to your undercloud and source the overcloud authentication file <NOTE: I think there is a template for this in the common/global/ director>
source ~/overcloudrc

. Find which telemetry endpoints exist after upgrade:
openstack endpoint list | grep -i -e aodh -e gnocchi -e panko

. Delete the users of the missing endpoints:
openstack user delete aodh gnocchi panko
