In addition to monitoring buckets over all the nodes within the cluster, Couchbase Server also includes support for monitoring the statistics for an individual node.
The Server Nodes monitoring overview shows summary data for the Swap Usage, RAM Usage, CPU Usage and Active Items across all the nodes in your cluster.
Clicking the server name provides server node specific information, including the IP address, OS, Couchbase version and Memory and Disk allocation information.
Selecting a server from the list shows a server-specific version of the Bucket Monitoring overview, showing a combination of the server-specific performance information, and the overall statistic information for the bucket across all nodes.
The graphs specific to the server are:
Amount of swap space in use on this server.
Amount of RAM available on this server.
Percentage of CPU utilized across all cores on the selected server.
Number of connects to this server of all types for client, proxy, TAP requests and internal statistics.
You can select an individual bucket and server to view a statistic for using the popup selections for the server and bucket, and clicking on the mini-graph for a given statistic.
For more information on the data bucket statistics, see Section 6.3, “Data Buckets”.
