Cisco Cisco MediaSense Release 8.5(1) Guía De Instalación

If you have set up the primary Unified MCP server to use the New Recording Priority mode,

then a recording can be deleted if any of the following situations occur:

•

The age of the recording is equal to or greater than the retention age configured in the Delete
recordings older than 60 days.

 field.

A day is identified as twenty fours from the precise time you change this setting--it is

not identified as a calender day. For example, if you change the retention period at 23.15.01

on April 2nd, 2010, the specified recordings will only be deleted at 23.15.01 on April 3rd,

2010. The recordings will not be deleted at 00:00:01 on April 3rd, 2010.

•

The disk usage has crossed the 95% mark

For example, if you are within your disk usage percentage and if you automatically wish to

delete all recordings older than 90 days, you must enter 90 in theDelete recordings older than
__ days.

 field. In this case, all recordings which are older than 90 days are automatically deleted.

Deleted recordings are not immediately removed from the meta database. Instead, they are

marked as deleted and removed from the database at off-peak hours. Disk I/O is expensive. A

batch delete of multiple database records at off-peak hours reduces the impact on the system

during critical hours. The routine is currently scheduled to run at 12 AM (local server time)

daily, at which time the deleted recordings are physically removed from the disk. If a session

is automatically pruned, it is marked as deleted, but it will not be removed by this scheduled

routine. You must use the 

API explicitly to remove automatically-pruned

recordings from the disk.

To configure the number of days to delete old recordings in the New Recording Priority mode,

follow this procedure:

Select Administration > Prune Policy Configuration from the Unified MCP Administration.

The Unified MCP Prune Policy Configuration web page opens to display the configured number

of days to delete old Unified MCP recordings. The allowed range is from 1 to 180 days (default

is 60 days).

Change the number of days for recording to be deleted and click Save to apply your changes.

The page refreshes to display the newly-configured number of days.

If you prefer to revert to the default of 60 days, click Reset.

Avoiding Data Pruning

An API event is issued each time the storage disk space (which stores the recorded media)

reaches various thresholds. You can select the Old Recording Retention mode and judiciously

follow all threshold alerts by deleting unwanted recordings. By doing so, you can conserve

space for the recordings which are required.
