History Retention Settings

The Polycom RealPresence DMA system is preconfigured with the number of history records of various types to retain. When the retention limit for a record type is reached, the system purges a specific number of the oldest records of that type.

The following table shows the retention limit for each record type and how many are purged at a time when the retention limit is reached. The values specified are for each cluster, not the total for the entire supercluster.

		Number of Records Purged
Record Type	Retention Limit	When Limit Is Reached
Registration history	505,000	5,000
Registration signaling	2,000,000	20,000
Call history	505,000	5,000
Call signaling history	12,625,000	125,000
Conference history	202,000	2,000
CDR export history	11,000	1,000

Contact Polycom Global Services if you want to discuss the possibility of changing the retention limits.

The History Retention Settings page lets you specify whether to retain registration history records, and if so, whether to include registration keep-alive messages. You can also specify how many repeated low-value signaling records to retain. The following table describes the fields on the page. Only users with the Auditor role can access this page.

The settings on this page are supercluster-wide (the clusters aren’t independently configured).

Field	Description
Enable recording of	Enables the system to retain Call Server registration records (see Registration
registration history	History Report on page 407).
Include keep-alive messages	If selected, the Call Server history includes the keep-alive messages sent by
in registration history	registered endpoints and the Call Server’s responses.
	Selecting this option significantly increases the number of Call Server registration
	records per period of time.
Number of repeated low-value	The number of less-important signaling messages (such as INFO messages
signaling event records to	about in-call status) to retain for a given call (from 0 to 10; default is 3).
retain	Once the limit is reached, subsequent messages of that type are processed, but
	not recorded in the call signaling history.
