Ipswitch WhatsUp Gold User Guide
Using information gathered from the database, Flow Monitor will approximate the growth
rate of the database, and adjust the retention settings to ensure that the total size of the
database is maintained in the recommended band of a minimum of 1 million to a maximum
of 10 million flow records. The recommended band is based on storage requirements for
each stage in the data retention strategy.
When you manually adjust the Data Retention settings (Auto tune flow data retention
option is cleared), you will be presented with guidance in the message area at the bottom of
the dialog as you adjust each setting. This feedback provides you with information about
how the current or proposed setting will affect the database size with respect to the
maximum recommended database size (10 million records).
For the raw data, hourly data, and daily data, the maximum recommended database size is
compared against all of the data in these categories and is based on the size of the Flow
Monitor Active database. For the Archive daily data after setting, the guidance is based on
the size of the Flow Monitor Archive database.
Configuring data retention settings
Flow Monitor is designed to serve two primary purposes:
To give a minute-by-minute view of recent network traffic.
To give an overview of historical network traffic.
To accomplish these goals while keeping the size of its database reasonable, Flow Monitor
uses a process of summarizing data at certain time intervals.
By default, Flow Monitor rolls up data on this schedule:
Complete raw data (which is collected every other minute and provides the detailed
view of recent traffic) is kept for 4 hours.
After 4 hours, raw data is summarized into hourly averages.
After 1 days, hourly averages are summarized into daily averages.
After 3 days, daily data is archived.
After 7 days, archive data is purged from the archive database.
To configure the data collection interval:
1 Navigate to the Flow Monitor Settings dialog (Flow Monitor > Settings).
2 In the Data collection interval box, select how often you want Flow Monitor to write
raw data from its sources to the Flow Monitor Active database. You may select 1, 2, 3, 4,
5, or 10 minutes. By default, raw data is written to the database every 2 minutes.
3 Click OK. The setting is saved and the Flow Monitor Settings dialog closes.
