Resource Monitors | Monitoring
Editor
Monitors may share a retention policy. The retention policy controls how long data is held per roll-
up period. The editor for Retention policies lets you assign characteristics and monitors to them.
General Retention Policy Options
The editor contains the following fields:
Policy Name —A text identifier for the policy.
Description —An optional description for the policy.
Detail / Hourly / Daily Data (Days) —How many days to retain the selected data.
The amount retained has both a performance and data storage impact. For example, retaining
day’s information from an active performance SNMP monitor configured with one target’s
worth of data, retrieved on one minute intervals can consume 0.7 G of database, and require
21 inserts per second.
Traffic flow analysis can process and retain even larger amounts of information. Flows that
correlate 50%, polled every minute for a day require roughly 109G of database, and require
4500 inserts per second.
