Note
In this case, each file or process instance is monitored separately by ASAP and could
produce slightly different results depending on timing and other factors.
Domain Aggregation
ASAP lets you aggregate File and Process domains at any level of the hierarchical
group name. ASAP can automatically construct aggregate domains for all objects at all
levels using a global parameter setting, or you can define only the necessary
aggregate domains for individual groups (recommended). Aggregate domain names
are constructed using the # character as the level name. For example, the aggregate
domain Sales\# represents the combination of all domains in the Sales group.
Similarly, Sales\Orders\# represents all members of the Sales\Order group.
There are two ways to turn on aggregation for files and processes being monitored as
a part of a hierarchical group.
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 and the PROCESS Command.
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.
