Resolve public address interval. When the Flow Monitor collector service
encounters an IP address, it tries to determine information about the host attached to
the IP address. After this information is resolved, it is stored in the Flow Monitor
database. Enter the interval (in hours) that you want Flow Monitor to wait, before it
checks the public IP address again, to resolve information that may have changed on
the address. By default, public addresses are resolved every 720 hours (30 days).
Tip: Because public IP addresses are less likely to be changed, you may want to use longer
intervals than used for the Resolve private address interval option.
Expire unclassified traffic after. Enter the number of hours after which Flow
Monitor should purge unclassified traffic. Unclassified traffic is traffic transmitted over
ports that are currently not monitored by Flow Monitor. By default, this option is set
to 0 (zero), which causes Flow Monitor to aggregate and retain data for all
unclassified ports as a single value; detailed information about the individual
unclassified ports over which traffic was transmitted is immediately discarded.
Note: The collector will purge any unclassified data that has no activity after the Expire
unclassified traffic after value is satisfied.
You can use the data retention section of the Flow Monitor Settings dialog to set data
retention parameters for flow and interface data. Periodic roll-up and archival of flow data
minimizes system resources needed for data storage and improves system responsive during
data intensive operations.
Data retention settings
Flow data includes many parameters (input and output interfaces, source and destination IP
addresses, port numbers, byte rates, flow end times, etc.) which while useful in providing
information may quickly fill available storage. Rolling up the data makes for efficient storage,
but there may be losses of time related information within individual flows. Flow Monitor
provides a data retention scheme that allows the user to choose to either manually tune data
retention or to allow Flow Monitor to automatically tune the retention of flow data, which in
turn actively manages the growth rate of the Flow Monitor databases. The following
parameters are used to control the cleanup of flow data.
Auto tune flow data retention. Select this option if you want Flow Monitor to
automatically tune the flow data cleanup settings to manage database size and
system performance. This option is selected by default.
Percentage of traffic to retain. Use this option to determine the percentage of raw
traffic the collector will write to the database. This option is enabled when you clear
the Auto tune flow data retention check box.
