Identify network bottlenecks with Top Lists

Configuration

Prerequisites

you must configure your environments NetFlow or sFlow according to the technologies used and instantiate the service models NetworkAnalysis-NetFlow-TOPList or NetworkAnalysis-sFlow-TOPList.

  • Collector Storage: Collector Storage Ip
  • Type of TOP List: Enter the values 1, 2 or 3 depending on the TOP List you want:
    • 1 for Top Talkers

  • Only alert in percentage: Bandwidth usage alert threshold in percentage
  • The only criticism in percentage terms: Critical bandwidth usage threshold in percent

Service models NetworkAnalysis-NetFlow-TOPList  and NetworkAnalysis-sFlow-TOPList can be linked to the equipment on which NetFlow and sFlow or any other device, perhaps a dummy device that would centralize all network analysis services.

As a best practice, it is recommended to instantiate at least one NetworkAnalysis-xFlow-TOPList by Top Lists.

If no data are available, please refer to the documentation NetFlow (Checks and Debug sections) or sFlow
