Network Quality Metrics (Plug-ins Required)

The network quality of connections is monitored using two plug-ins, and there are two key metrics: network latency and packet loss rate.

The following are the two plug-ins:

dc-nqa-collector: monitors the connections requested using the Direct Connect console.
history-dc-nqa-collector: monitors historical connections.

Automated connections are requested using the console and can be self-service or 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 requested by email or phone do not have virtual gateways and virtual interfaces, and their routes must be configured manually. This type of connection is only available in some regions.

Configure the Direct Connect plug-ins.
For details, see Installing Direct Connect Metric Collection Plug-ins.
Configure the return route for the detection source IP address in the on-premises data center.
Example route (A Huawei-developed device is used an example.)
```
ip route-static 192.168.1.100 255.255.255.255 10.0.0.1
```
This is to add a return route whose destination is the detection source IP address used in the on-premises data center and next hop is the local gateway configured on the corresponding virtual interface. This ensures that the return packets from the on-premises data center can reach the detection source in the VPC through the correct path.
