Resetting a baseline

Baseline can be reset to re-compute the baseline. On Reset, the baseline data is re-initialized based on previous data generated from the same instances.

All historic baseline information is deleted and the new baseline is initially just an estimate (based on the performance of the old data in the specified period).

Baseline values are refined over time as the pattern is relearned.

To reset a baseline

1. Click Reset Baseline on the baseline Administration screen.
2. Select the monitor instances.
   • Group - Select Group to include all the instances in the group.
   • SLO - Select SLO to include all instances from the SLO.
   • Device - Select Device to include all the instances associated with the device.
   • Monitor Type - Select Monitor Type to include all instances of the monitor type.
   • Monitor Instance - Select Monitor Instance to include the single monitor instance.
3. Specify the period for calculating the new baseline by using one of the following options:
   • From Time and To Time - Specify the start and end time of the period for considering data for baseline calculations.
   • Number of days for considering data
4. Select the baseline types to be reset. Specify at least one of available baseline types (hourly, daily, or weekly).

5. Click Reset.

   Note

   • Baseline reset at the attribute level does not change historic values. It modifies only baseline values computed for future use.
   • If you select All Attributes as the Monitor Attribute Selector, then all baseline values of the current day are reset. If you select a single attribute, then the attribute baseline value of the current hour is reset.
   • Baseline Administration is available only to the following types of users:
     • Users who have administrator privileges.
     • Users who have access to all CIs and have permission for baseline administration.
        This option is not available to restricted users even if they have been assigned the required permissions.
