Within the Data Bucket monitor display, information is shown by default for the entire Couchbase Server cluster. The information is aggregated from all the server nodes within the configured cluster for the selected bucket.
The following functionality is available through this display, and is common to all the graphs and statistics display within the web console.
The Data Buckets selection list allows you to select which of the buckets configured on your cluster is to be used as the basis for the graph display. The statistics shown are agregated over the whole cluster for the selected bucket.
The Server Selection option enables you to limit the display to an individual server or entire cluster. You can select an individual node, which displays the Section 6.2, “Viewing Server Nodes” for that node. Selecting All Server Nodes shows the Section 6.3, “Viewing Data Buckets” page.
The Interval Selection at the top of the main graph changes interval display for all graphs displayed on the page. For example, selecting Minute shows information for the last minute, continuously updating.
As the selected interval increases, the amount of statistical data displayed will depend on how long your cluster has been running.
All of the graphs within the display update simultaneously. Clicking on any of the smaller graphs will promote that graph to be displayed as the main graph for the page.
Individual Server Selection
Clicking the blue triangle next to any of the smaller statistics graphs enables you to show the selected statistic individuall for each server within the cluster, instead of aggregating the information for the entire cluster.
