In order to increase Usage performance, you can configure “drop-port” compression on Usage interfaces. This technique drops port information from nfcapd files and results in significant compression of Usage data with a corresponding increase in responsiveness. Drop-port compression is enabled by default on all 10Gbps and faster Usage interfaces.

This feature is controlled from the monitoring point Admin API.

View Usage interfaces

Return a list of Usage interfaces on the monitoring point.

Admin API

  1. Access the Admin API.
  2. Navigate to Flow > GET /flow/interface/.
  3. Click Try it out.
  4. Click Execute.
    • The Response body field shows a list of Usage interfaces on the monitoring point.

View Usage interface compression configuration

Return the configuration of a Usage interface.

Admin API

  1. Access the Admin API.
  2. Navigate to Flow > GET /flow/interface/{interface_name}.
  3. Click Try it out.
  4. In the interface_name field, specify the Usage interface you are interested in (e.g. “eth5”).
  5. Click Execute.
    • The Response body field shows the drop_port_enabled configuration. If set to true, drop-port compression is enabled on the port. If set to false there is no compression.

Enable compression on a Usage interface

Admin API

  1. Access the Admin API.
  2. Navigate to Flow > PUT /flow/interface/{interface_name}.
  3. Click Try it out.
  4. In the interface_name field, specify the Usage interface you are configuring (e.g. “eth5”).
  5. In the body field, specify: “drop_port_enabled”: true
  6. Click Execute.
    • The Response body field should contain “status”: 200.

Disable compression on a Usage interface

Admin API

  1. Access the Admin API.
  2. Navigate to Flow > PUT /flow/interface/{interface_name}.
  3. Click Try it out.
  4. In the interface_name field, specify the Usage interface you are configuring (e.g. “eth5”).
  5. In the body field, specify: “drop_port_enabled”: false
  6. Click Execute.
    • The Response body field should contain “status”: 200.
