Hi, I am using pike version. I have configured nova service as mentioned in https://docs.openstack.org/keystonemiddleware/pike/audit.html 1. added in api-paste.ini file [ filter : audit ] paste . filter_factory = keystonemiddleware . audit : filter_factory audit_map_file = / etc / nova / api_audit_map . conf 2. verified composite:openstack_compute_api_v2 section. 3. Copied the api_audit_map.conf file to the /etc/nova/ After that I have restared all openstack services. But I couldn't find any audit logs with oslo.messaging.notification.audit.http.request in nova.log file I can see only logs related to oslo.messaging as openstack nova-scheduler[17534]: INFO oslo.messaging.notification.scheduler.select_destinations.start [None req-01612e5a-37d9-4b62-970a-fcf7d3c409ad admin admin] {"event_type": "scheduler.select_destinations.start", "timestamp": "2021-04-25 11:10:40.249260", "payload": {"request_spec": {"instance_properties": {"root_gb": 1, "uuid": "ee4ddae2-9397-401c-b80f-543061e75dd2", "availability_zone": null, "ephemeral_gb": 0, "numa_topology": null, "memory_mb": 512, "vcpus": 1, "project_id": "d078fd26a1204e6abede5faca777da8b", "pci_requests": {"requests": []}}, "instance_type": {"disabled": false, "root_gb": 1, "name": "m1.tiny", "flavorid": "1", "deleted": false, "created_at": "2021-04-22T17:34:26.000000", "ephemeral_gb": 0, "updated_at": null, "memory_mb": 512, "vcpus": 1, "extra_specs": {}, "swap": 0, "rxtx_factor": 1.0, "is_public": true, "deleted_at": null, "vcpu_weight": 0, "id": 6}, "image": {"status": "active", "name": "cirros-0.3.5-x86_64-disk", "container_format": "bare", "created_at": "2021-04-22T17:32:54.000000", "disk_format": "qcow2", "updated_at": "2021-04-22T17:32:55.000000", "id": "e0d062fa-2b3c-4a6e-90e4-3ef796c3a594", "min_disk": 0, "min_ram": 0, "checksum": "f8ab98ff5e73ebab884d80c9dc9c7290", "owner": "d078fd26a1204e6abede5faca777da8b", "properties": {}, "size": 13267968}, "num_instances": 1}}, "priority": "INFO", "publisher_id": "scheduler.openstack", "message_id": "3128ed95-1599-46f8-b110-93fcb0776812"} what I understood that as part of audit middleware, logs should contain oslo.messaging.notification.audit.http.request and oslo.messaging.notification.audit.http.response. Please suggest what I am missing. Thanks, Hanumantha Reddy.
