A ``--task-log`` option has been added to the ``nova-manage db
|
|
archive_deleted_rows`` CLI. When ``--task-log`` is specified, ``task_log``
|
|
table records will be archived while archiving the database. The
|
|
``--task-log`` option works in conjunction with ``--before`` if operators
|
|
desire archiving only records that are older than ``<date>``. The
|
|
``updated_at`` field is used by ``--task-log --before <date>`` to determine
|
|
the age of a ``task_log`` record for archival.
|
|
|
|
The ``task_log`` database table contains instance usage audit records if
|
|
``nova-compute`` has been configured with ``[DEFAULT]instance_usage_audit =
|
|
True``. This will be the case if OpenStack Telemetry is being used in the
|
|
deployment, as the option causes Nova to generate audit notifications that
|
|
Telemetry consumes from the message bus.
|
|
|
|
Usage data can also be later retrieved by calling the
|
|
``/os-instance_usage_audit_log`` REST API [1].
|
|
|
|
Historically, there has been no way to delete ``task_log`` table records
|
|
other than manual database modification. Because of this, ``task_log``
|
|
records could pile up over time and operators are forced to perform manual
|
|
steps to periodically truncate the ``task_log`` table.
