This commit integrates 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:
- puppet changes to add gnocchi user and endpoints to keystone, gnocchi
port to haproxy and firewall,
remote logging as well as other necessary configurations for gnocchi
- backup restore for gnocchi postgres db (except metric and resource
tables)
- sm changes to manage gnocchi processes through created lsb scripts
- support for multi-region setup
- distributed cloud - do not enable service and create endpoints for
gnocchi in system controller
- add gnocchi logs in syslog
- support no reboot patching for gnocchi processes
- add gnocchiclient in remote CLI
- add NotIn validation method in python-voluptuous which needed in
gnocchi
- collect scripts updates
- cleanup ceilometer api and collector in puppet configuration, sm,
service parameter, syslog, remotelogging, patch-restart-processes
- remote ceilometerclient from remote CLI
- remote openstack client changes for ceilometer CLI extensions
- remove ceilometer-api and ceilometer-collector packages from iso
