Database space management
The NTA Database Space feature provides current NTA database disk usage and usage trend statistics
over the last twenty-four hours. Otherwise, you can query NTA for usage trends for the last 7 days, 30
days, 3 months, or for a user-defined time range. This feature, when combined with the threshold and
action parameters (Usage Threshold of the Database Disk and When Database Disk Usage Reaches
Threshold, respectively) of an NTA server configuration, enables you to proactively manage disk space
usage and ensure adequate disk space for uninterrupted NTA functioning.
The granularity of the database space usage information varies with the span of the query time. The
longer the time span of the query, the coarser the granularity. The shorter the time span of the query, the
finer the granularity. The finest granularity is 10 minutes. When the NTA service module and database
are installed separately, this feature is not available.
The following information describes the Database Space feature for viewing current NTA database disk
space usage. For information on viewing and configuring the database threshold and action settings,
see " Managing NTA servers ."
