Hi. how can i find a simple, correct, ceilometer configuration for "yoga" version of openstack? 1) I followed this instruction guide <https://docs.openstack.org/ceilometer/latest/install/> step by step! 2) I installed devstack with enabled ceilometer (and gnocchi as backend) but after both tries mentioned above, i did not see any metric. I also changed the publisher from gnocchi:// into file:// but the result did not change. cat /etc/ceilometer/ceilometer.conf: [DEFAULT] transport_url = rabbit://stackrabbit:bsvbr5pzLpN0szN84v3m@127.0.0.1:5672/ use_syslog = True [oslo_messaging_notifications] topics = notifications driver = messagingv2 [coordination] backend_url = redis://localhost:6379 [notification] workers = 4 [cache] backend_argument = url:redis://localhost:6379 backend_argument = distributed_lock:True backend_argument = db:0 backend_argument = redis_expiration_time:600 backend = dogpile.cache.redis enabled = True [service_credentials] auth_url = http://127.0.0.1/identity region_name = RegionOne password = bsvbr5pzLpN0szN84v3m username = ceilometer project_name = service project_domain_id = default user_domain_id = default auth_type = password [keystone_authtoken] memcached_servers = localhost:11211 cafile = /opt/stack/data/ca-bundle.pem project_domain_name = Default project_name = service user_domain_name = Default password = bsvbr5pzLpN0szN84v3m username = ceilometer auth_url = http://127.0.0.1/identity interface = public auth_type = password _________________________________________ cat /etc/ceilometer/pipeline.yaml: --- sources: - name: meter_source meters: - "*" sinks: - meter_sink sinks: - name: meter_sink publishers: - file:///tmp/ceilofile?json # - gnocchi://?archive_policy=low&filter_project=service ____________________________ cat /etc/ceilometer/polling.yaml --- sources: - name: all_pollsters interval: 300 meters: - "*" _____________________________ root@os-aio:/# cat /etc/gnocchi/gnocchi.conf [DEFAULT] debug = True coordination_url = redis://localhost:6379 [indexer] url = mysql+pymysql:// root:bsvbr5pzLpN0szN84v3m@127.0.0.1/gnocchi?charset=utf8 [storage] redis_url = redis://localhost:6379 driver = redis [metricd] metric_processing_delay = 5 [api] auth_mode = keystone [keystone_authtoken] memcached_servers = localhost:11211 cafile = /opt/stack/data/ca-bundle.pem project_domain_name = Default project_name = service user_domain_name = Default password = bsvbr5pzLpN0szN84v3m username = gnocchi auth_url = http://127.0.0.1/identity interface = public auth_type = password
