EV Observe - Use NetworkAnalysis-NetFlow-TOPList / NetworkAnalysis-sFlow-TOPList ServiceTemplates

Last modified on 2023/05/24 14:10

The NetworkAnalysis-NetFlow-TOPList and NetworkAnalysis-sFlow-TOPList service templates identify the top list of IP addresses (talkers), connections and protocols with the highest network bandwidth consumption in a NetFlow or sFlow environment.

  • They are used to monitor and analyze bandwidth consumption over a given period and provide a detailed view of network traffic.
  • You can display the data in a Dataviz using the Network analysis widget.
  • You can define alerts to be triggered if the thresholds specified for network bandwidth consumption are exceeded.
     

NetworkTrafficMonitoringChallenges

Challenges in network traffic monitoring

  • Identify the users, applications and protocols with the highest bandwidth consumption in order to optimize the performance of the infrastructure and Internet access costs, and improve the quality of service.
  • Anticipate the risk of incidents and adopt measures to prevent technical network failure.
  • Define bandwidth consumption strategies, implement the required corrective measures and anticipate bandwidth upgrades.
  • Identify the causes of bandwidth bottlenecks rapidly to ensure a return to normal operations as quickly as possible.

Notes

  • You can associate the templates with a host where NetFlow or sFlow is configured, or with a virtual host that centralizes network analysis services.
  • NetFlow or sFlow must be enabled for the monitored device.

Best Practice

  • Build a Dataviz using the Network analysis widget to display the trends loaded by the templates.
  • Deploy one or more NetworkAnalysis-NetFlow-TOPList or NetworkAnalysis-sFlow-TOPList services by top list.

Procedure: How to use the service templates

Prerequisites

Note: You must adapt the prerequisites depending on whether your environment is NetFlow or sFlow.

Step 1: Create the new service

SelectCompanyInCompanyTree_Procedure

1. Go to the Web app.

2. Select the company from the company tree structure.

Notes:

  • The selected company must be associated with a Box.
  • You can create a new company. Open url.png See the procedure

3. Create a new service.

  • Select Configuration > Services > List in the menu.
  • Click + Add in the Mode: Box tab. 

4. Specify the information below.

General information tab

  • Service template: Select the NetworkAnalysis-NetFlow-TOPList or NetworkAnalysis-sFlow-TOPList template depending on whether your environment is NetFlow or sFlow.
  • Name: Enter the name of the new service to be created. Its name should correspond to the event to be captured.

  • Collector Storage: IP address of the NetFlow or sFlow collector.
  • Top list type: Type of top list to display in the Dataviz.
    • 1: Top talkers, for the IP addresses with the highest bandwidth consumption.
    • 2: Top connections, for the data flows with the highest bandwidth consumption.
    • 3: Top protocols, for the applications with the highest bandwidth consumption.
  • Top Count: Number of records to be displayed in the top list.

example    10 ==> Display the top ten

  • Analysis period in the selected time unit: Number indicating the analysis period of the top list, expressed in the selected time unit.
  • Selected time unit: Unit expressed in minutes (m), hours (h) or days (d).

example    Period = 10; Time unit = days ==> The top list will show trends over a period of ten days

  • Directory name: Path to the folder containing the NetFlow or sFlow exports.
  • Warning threshold in percent: Warning threshold for bandwidth consumption, expressed as a percentage.
  • Critical threshold in percent: Critical threshold for bandwidth consumption, expressed as a percentage.

5. Click Apply.
 

Step 2: Create a Dataviz using the Network analysis widget
