In addition to monitoring buckets over all the nodes within the cluster, Membase 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 button provides server node specific information, including the IP address, OS, Membase 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:
swap usage
Amount of swap space in use on this server.
free memory
Amount of RAM available on this server.
CPU utilization
Percentage of CPU utilized across all cores on the selected server.
connection count
Number of connects to this server of all types for client, proxy, TAP requests and internal statistics.
By clicking on the blue triangle against an individual statistic within the server monitoring display, you can optionally select to view the information for a specific bucket-statistic on an individual server, instead of across the entire cluster.
For more information on the data bucket statistics, see Section 4.1.3, “Manage Data Buckets”.
