The WebUI provides a view of network metrics within ECS. For instance, the average bandwidth of the network interfaces on the nodes can be viewed in the Node and Process Health page. The Traffic Metrics page provides read and write metrics at the site and individual node level. It shows the read and write latency in milliseconds, the read and write bandwidth in bytes/second and read and write transactions per second.
The Geo-Replication monitor page shows information relating to geo-replication occurring between sites. For instance, the rates and chunks pages provide the current read and write rates for geo-replication and the chunks broken down by user data, metadata, and XOR data pending for replication by replication group or remote site. The ECS portal also provides a way to filter based on timeframe to get a historical view of traffic. Note that updates to any rate information in the ECS portal can take some time. For more information about the ECS Portal, see the most recent ECS Administration Guide.
