Introducing System Metrics Collection
What is System Metrics Collection, and how does it work on Expressway?
System Metrics Collection is a feature on Expressway that publishes system performance statistics, enabling remote
monitoring of performance.
monitoring of performance.
The Expressway collects statistics about the performance of the hardware, OS, and the application, and publishes these
statistics to a remote host (typically a data analytics server) that aggregates the data.

Where do I configure System Metrics Collection?
You can configure this feature on Expressway via the web interface or the command line. The configuration from one
peer applies throughout the cluster, so we recommend that you configure it on the master peer if you are monitoring a

There is also some configuration required on the remote server; the collectd daemon should be running on the server,
and should have the collectd network plugin configured to listen on an address that can be seen by the clients. Further
details depend on your monitoring environment and are beyond the scope of this information.
