Central Network Metrics

Overview

By setting up a central network, you can enable communications between enterprise routers, as well as between enterprise routers and your on-premises data center, in the same region or across regions. When a central network is used, attachments on the enterprise routers used in the central network policy will be monitored.

This section describes metrics reported by enterprise routers in the central network policy to Cloud Eye as well as their namespaces and dimensions. You can view the metrics on the Cloud Eye console.
