Hi，I guess it is an issue with the hostname. It use a fqdn hostname in nova-compute services such as ‘lab-11053-26006-cmp-1.cluster.local’ but use a short hostname ‘lab-11053-26006-cmp-1’ in masakari-monitors. You can configurate a fqdn hostname in masakari-monitors as bellow, [default] hostname= lab-11053-26006-cmp-1.cluster.local(example) Otherwise, it would use a short hostname. masakarimonitors/conf/service.py service_opts = [ cfg.StrOpt('hostname', default=socket.gethostname(), deprecated_name="host", help=''' Hostname, FQDN or IP address of this host. Must be valid within AMQP key. Possible values: * String with hostname, FQDN or IP address. Default is hostname of this host.

Am i missing some conf? is there any need to add some conf in nova and keystone too? in masakari engine logs i see host_failure.evacuate_all_instances = True instance_failure.process_all_instances = False host_failure.add_reserved_host_to_aggregate = False host_failure.ha_enabled_instance_metadata_key = HA_Enabled log_opt_values host_failure.ignore_instances_in_error_state = False host_failure.service_disable_reason = Masakari detected host failed. and i get below error when i turn off an instance on the compute, logs are from masakari-instance-monitor 2024-01-03 13:01:15.574 1 DEBUG openstack.resource [-] Attribute [] not found in [<openstack.resource._ComponentManager object at 0x7fa051f48730>]: ''. __getattribute__ /var/lib/openstack/lib/python3.8/site-packages/openstack/resource.py:622 2024-01-03 13:01:15.595 1 WARNING masakarimonitors.ha.masakari [-] Retry sending a notification.

(do i need to create some masakari notifications for it to work in openstack? if yes how may i do it) below i have attached the logs from masakari-hostmonitor and masakari-engine and also some components which i created in openstack about masakari do you have any suggestion please let me know! Thank You
