    PRODUCT:

    TrueSight Capacity Optimization


    COMPONENT:

    Capacity Optimization


    APPLIES TO:

    TSCO 11.3.01, 11.5.01



    PROBLEM:

    After upgrading from 10.7 to 11.3.01, I have noticed this task is actually running and performing an activity of deleting Series. What changed between 10.7 and 11.3.01 regarding this System Task? There is no documentation on what this task does. 

    We do not have Automatic Purging configured either, but it appears this task is purging data regardless.

    SOLUTION:

     

    Entities cleaner task is responsible of purging entities and old series. 

      

    For the entities, this task cleanup:

      
       
    • The entities you selected to delete in the Unassigned page in Works session
    •  
    • The systems that are no more reporting data, according with the setting in Aging Configuration page
    The task also cleanup the metrics that are no more reporting data according with the Aging setting (and can't be queried by any component of TSCO).   

    In detail, the task selects all the metrics that have an activity date older than the days specified in the month section of aging configuration, taking care also of the different configurations for short, medium and long aging.
