  • 1.  Long Term history

    Posted Sep 21, 2017 04:46 AM

    DEFINITION :


    The Long-Term History allows you to analyze and identify trends. The collection step is 5 minutes (minimum) corresponding to all data beyond the short-term history. The metrics are stored on the disk.

     

     

    PERIODICITY : 

    • 5 minutes (not editable) for Unix and Windows Agents
    • The period can be changed from 5 to 90 minutes for OS / 400 and database agents.
    • An interval of 5 minutes is a good compromise between the accuracy of the data and the phenomena of not significant peaks
    • All collected metrics are archived in the local database:
