Identify network bottlenecks with Top Lists

Configuration

Pre-requisites

you need to configure your environments NetFlow or sFlow according to the technologies used and then deploy the service templates NetworkAnalysis-NetFlow-TOPList or NetworkAnalysis-sFlow-TOPList.

Complete the various fields:

  • Collector Storage: Collector Storage server IP
  • TOP list type: Enter the values 1, 2 or 3 according to the desired TOP List:
    • 1 for Top Talkers
    • 2 for Top Connections
    • 3 for Top Protocols
  • Number of entries: number of entries in Top List
  • Analysis period: Time value coupled with the field "Time unit".
  • Period unit:Choice of the unit of time, m for minute, h for hour, d for day.
  • Directory name: Path to the directory containing the NetFlow or sFlow exports
  • Warning threshold: Warning bandwidth usage threshold in percent
  • Critical threshold: Critical bandwidth usage threshold in percent

Service Templates NetworkAnalysis-NetFlow-TOPList  NetworkAnalysis-sFlow-TOPList can be linked to the host on which NetFlow sFlow are configured, or any other host;it could in fact be a "dummy" host used to centrallise all ServiceNav network analysis services.

Best practice is to deploy at least one NetworkAnalysis-xFlow-TOPList service.

If no data is presented, please refer to the Checks and Debug sections of the documentation for NetFlow or sFlow
