  • AWS Configuration: Set parameters for Amazon Web Services flow streaming configuration here.
  • CrossCheck: Specify the thresholds for changing color and the syslog threshold that the Fault Index must reach to trigger a syslog.
  • Data History: Specify how long each flow interval is saved.
  • Historical 1 Min Avg: Saves 100% of all flows received. Make sure the server has enough disk space to save significant quantities of the raw flows. The 1 minute intervals consume the most disk space as it is not aggregated and flows are in raw format.

  • Historical 5 minute - 1 week Avg: These intervals only save the specified Maximum Conversations after aggregation per interval.

  • Maximum Conversations: Used when creating large intervals (e.g. 5 minute) from prior intervals (e.g. 1 minute). All flows are aggregated together per router. The top 1,000 (default) based on bytes are saved.


    The default value for the Flow Maximum conversations field is 1,000 and the maximum value is 25,000.

-Auto History Trimming: This option allows for automatic database trimming when available disk space falls below 10% (with a minimum threshold of 10GB). Check the checkbox to activate this option. An alarm will also be generated to send an alert that the database is being trimmed (1 minute and 5 minute conversation database tables) and includes how much 1 minute and 5 minute data currently exists in the database (in hours).

In a distributed collector environment, each collector will perform the database trimming independent of the other collectors. Auto History Trimming on/off applies to all of the collectors in the cluster, but the database trimming will only occur on the server(s) that fall below 10% of available disk space.
