This is part of feature integrating gnocchi as metric storage backend
because of the deprecation of ceilometer metering backend.
With gnocchi integrated, ceilometer api and collector processes are
removed, ceilometer agent nofitication and polling processes
are still running to collect and normalise data from other openstack
services. Ceilometer notification agent also has the responsiblity
to send samples to gnocchi backend through its gnocchi publisher and
events to panko backend.
Two gnocchi processes are introduced, gnocchi api is REST API service
and gnocchi metricd is for metric computing and gnocchi CLI is
supported to query measures/metric from gnocchi backend. Ceilometer
service and user still need to be registered in keystone, but stop
creating endpoints. Gnocchi is a seperate user/service in keystone and
run on active controller licensing on port 8041
Changes in this commit:
- add uid gid for telemetry services
- remove the oslo cache configuration
- fix puppet gnocchi warning
- remove ceilometer and add gnocchi logs in syslog
