#Collect Network Data from Custom-Named Network Interfaces

#Function Overview

The platform supports collecting network data from custom-named network interfaces by modifying the configuration of the monitoring component, enabling you to view the network traffic information for these interfaces on the monitoring page.

#Use Case

This is applicable when your nodes use custom-named network interfaces (not following the eth.|en.|wl.*|ww.* naming conventions) and require monitoring of these interfaces' network traffic data in the platform.

#Prerequisites

• A workload cluster has been created
• You have platform administrator permissions
• The naming conventions for the custom network interfaces are known

#Procedures to Operate

1. Click the CLI tool icon in the top navigation bar of the platform.

2. Click global.

3. In the global cluster, find the moduleinfo resource name corresponding to your workload cluster:

   kubectl get moduleinfo | grep -E 'prometheus|victoriametrics'
   

   Example output:

   global-6448ef7f7e5e3924c1629fad826372e7 global prometheus prometheus Running v3.15.0-zz231204040711-9d1fc12474c2 v3.15.0-zz231204040711-9d1fc12474c2 v3.15.0-zz231204040711-9d1fc12474c2 ovn-0954f21f0359720e8c115804376b3e7e ovn prometheus prometheus Running v3.15.0-zz231204040711-9d1fc12474c2 v3.15.0-zz231204040711-9d1fc12474c2 v3.15.0-zz231204040711-9d1fc12474c2

4. Edit the moduleinfo resource of the workload cluster:

   kubectl edit moduleinfo <moduleinfo resource name of the workload cluster>
   

5. Add or modify the valuesOverride field:

   spec:
     valuesOverride:# If this field does not exist, you need to add the valuesOverride field under spec along with the parameters below
       ait/chart-cpaas-monitor:
         global: 
           indicator:
             networkDevice: eth.*|em.*|en.*|wl.*|ww.*|[A-Z].*i|custom_interface # Replace custom_interface with the custom regular expression to ensure correct matching of the network interface name
   

6. After waiting for 10 minutes, check the network-related charts on the node's monitoring page to ensure the changes have taken effect.

#Operation Results

Once the configuration is effective, you can view the following data of the custom-named network interfaces on the platform's monitoring page:

• Network traffic data
• Network throughput
• Network packet statistics

#Subsequent Actions

• Monitor the performance metrics of the custom network interfaces
• Set alert rules based on the monitoring data
