From the Traffic Analysis Log Aggregation Policy list, select the aggregation policy you want to
apply to all log files processed by this NTA server. Options are:
•
No Aggregation (Best Report Timeliness)—This option does not aggregate data, and is
suitable for environments that have high requirements on report timeliness. This aggregation
mode requires much disk space because a huge number of logs are generated.
•
Aggregation (Standard)—This option aggregates data at five-minute intervals and is suitable
for environments that have a medium number of logs generated and requires less disk space
than the No Aggregation mode and more disk space than the Aggregation (Rough
Granularity) mode.
•
Aggregation (Rough Granularity)—This option aggregates data at twenty-minute intervals
and is suitable for environments that have a small number of logs generated and requires the
least disk space.
11.
From the Filter Policy list, select the filter policy to discard any data you do not want to process and
report on. Options are the user-defined filters created using the NTA Filter Strategy feature and Not
Filter.

NTA before NTA either stops receiving logs or deletes logs to release disk space.
13.
From the When Database Disk Usage Reaches Threshold list, select the action you want NTA to
take when the NTA database disk or volume consumption exceeds the threshold you set
previously.
Options are:
•
Stop Receiving Logs—When the specified threshold or percent of disk space is reached, NTA
no longer processes and stores traffic analysis data until additional disk space is released or
added to the database disk or volume.
•
Delete Logs to Release Space—When the specified threshold or percent of disk space is
reached, NTA deletes existing logs from the oldest, until the disk space usage drops below the
threshold or percent.
