6.4. Tasks View
The Web Administration consists of a sizeable number of user-initiated actions to accomplish operations such as importing clusters. It is crucial for Web Administration users to monitor and view the status of the actions they initiated.
A user can view the following task information:
- The status of an initiated task whether completed or failed
- The details of all past and present cluster-wide initiated actions
- The timestamp of the initiated task
- Retrieve a specific task by using the available filters

The Task details will remain in the Web Administration interface for not more than the default Time to live (TTL) of 2 days. Once the timespan has elapsed, the task details will be discarded from the system.
