Network Quality Metrics (Agent Required)

Direct Connect plug-ins detect end-to-end network quality of connections and monitor two metrics of remote subnets: network latency and packet loss rate.

There are two types of plug-ins:

  • dc-nqa-collector: monitors the connections created on the Direct Connect console.
  • history-dc-nqa-collector: monitors historical connections.

For details, see Installing Direct Connect Metric Collection Plug-ins.

  • Automated connections are requested by yourself on the console and are classified into self-service connections and full-service connections. Each connection has at least a virtual gateway and a virtual interface, and their routes are automatically advertised. Connections in most regions are automated connections.
  • Historical connections are requested by email or phone. They do not have virtual gateways and virtual interfaces, and their routes must be manually configured. Historical connections exist only in some regions.
