Suspended audit state

https://blueprints.launchpad.net/watcher/+spec/suspended-audit-state

Problem description

If an audit with continuous mode needs to be stopped temporarily in order to execute an audit and then restarted, it will have to be deleted and recreated.

Use Cases

  • As an administrator, I want to suspend an audit with continuous mode to execute audit regularly for maintenance.
  • As an administrator, I want to resume the audit with continuous mode to execute audit after maintenance.

Proposed change

Currently, scheduler periodically picks up audit of PENDING, ONGOING or SUCCEEDED state. Then audit's job named execute_audit is added to scheduler. Execute_audit job first checks audit state. If state is CANCELLED, DELETED or FAILED, audit's job is removed and strategy is not executed.

This spec adds new audit state SUSPENDED and changes execute_audit's audit state check condition. If state is CANCELLED, DELETED, FAILED or SUSPENDED, audit's job is removed and strategy is not executed. Otherwise, strategy is executed.

Since SUSPENDED is new audit state, audit state transition check when updating audit state is also changed. ONGOING state can be changed to SUSPENDED. SUSPENDED can be changed to ONGOING in reverse.

Alternatives

  • Delete the audit and create again.
  • Currently, ONGOING state can be changed to CANCELLED state, but not be changed in reverse. If we can change from the CANCELLED state to ONGOING state, it is also an alternative.
