Creating Specific Aggregate Domains
(Recommended)
Creating Specific Aggregate Domains (Recommended)
To create an aggregate domain for hierarchically grouped files or processes, use the
MONITOR command to add the aggregate domain to the ASAP configuration. For
example, MONITOR PROCESS SALES\# causes ASAP to create the Sales\# domain
and to aggregate all domains starting with Sales into that domain.
Setting Global Aggregates for All Domains
An ASAPCONF parameter setting for File and Process, AGG, causes ASAP to
automatically create aggregate records at each level of any hierarchical file or process
name. If AGG is defined, you need not add aggregate domains to the database. ASAP
creates them automatically.
Aggregate Only Records
When monitoring thousands of files or processes, limit the amount of historical data
being stored by ASAP by configuring ASAP to write only aggregate domain records to
the database, leaving detail records in memory for command-based retrieval when
necessary. This solution can result in significant data reduction while still accurately
recording usage information for historical purposes.
When an aggregate domain issues an alert because a member domain has alerted,
ASAP provides the ability to retrieve information about the alerting file or process
directly from ASAP memory. For more information, see the MEMORY option for the
FILE Command on page 6-33 and the PROCESS Command on page 6-66.
There are two ways to turn on aggregation for objects being monitored as a part of a
hierarchical group and to write only the aggregate records to the ASAP database.
Creating Specific Aggregate-Only Domains (Recommended)
To cause ASAP to write only the aggregate record for a set of domains, use the
MONITOR command to add an aggregate domain using ## as the last level specifier.
For example, the command MONITOR PROCESS SALES\## causes ASAP to write
only the Sales\## record to disk. ASAP still computes data for each individual process
and then combines the data into the aggregate record, but it writes only the aggregate
record to disk.
Setting Global Aggregate Only for All Domains
An ASAPCONF parameter setting for File and Process, AGGONLY, causes ASAP to
automatically create aggregate records at each level of any hierarchical process name
and to write only the aggregate domains to the database. If AGGONLY is defined, you
need not add aggregate domains to the database. ASAP automatically creates them.
