COLLECT/ASAPDB

The ASAP database includes current and historical information about system

performance and the operational status of system objects. The ASAP database is

automatically created when the ASAP Collect process is first started. The Collect

process receives statistics and status messages from the ASAP and ASAPX monitors

throughout the network, parses the messages, and stores the information in the

normalized ASAP database.

The Collect process automatically maintains the database. The Collect process

includes database maintenance options that specify how much history to retain. You

can configure database history to only retain data since the last cleanup time; for

example, every night at midnight. Or you can configure it to retain ASAP history for a

much longer period of time, even indefinitely.

For more information about database maintenance options, see the SET RETAIN

command, SET DBMAXDAYS, SET DBMaxDaysToPurge,

SET DBRolloverSubvolPrefix, and the SET DBRolloverFilePrefix commands beginning

on page 6-87.

The ASAP Collector process is continuous. If a CPU fails, the backup Collector

process automatically takes over so that database access is always available. The

ASAP database is a real-time normalized database and can be queried online. The

ASAP product subvolume includes Enform queries that allow batch-type queries of

network performance and operational status.
