Configuring Metrics Roll-Up
NetIM regularly consolidates raw metric data it gathers from polled devices. Consolidation of metric data reduces the amount of storage space needed, thereby allowing historical data for a longer period to be saved in the database.
Data is consolidated in two ways:
• Raw metric data is “rolled up” into summary data at regular intervals.
• Old raw data is deleted (“aged out”) as it ages.
Data consolidation is described in
Roll-up/age-out scheme.
The roll-up and age-out schemes are preconfigured with default values for retention periods, which can be edited using the
Rollup wizard.
