The monitoring section of the Membase Web Console has been updated to provide more detailed information. The monitor section of the website is now divided into four sections:
Cluster Overview
Provides an overview of your Membase cluster, including RAM and disk usage, bucket activity and server status.
Data Buckets (updated in 1.7)
Provides overview statistics on all the configured buckets with a cluster. Clicking on a bucket within this view provides a much more detailed overview of the bucket statistics for your cluster. The statistics and graphs in this section have been expanded, and per-server as well as per-cluster statistics are now supported.
For more information, see Section 1.2, “Bucket Monitoring”.
Server Nodes (new in 1.7)
A new overview screen showing overall server statistics for your cluster. Selecting an individual server within the list displays a combined view of individual server statistics, and overall cluster statistics.
For more information, see Section 1.3, “Server Monitoring”.
Log
The Membase cluster log showing cluster events.
Withing the Data Bucket monitor display, information is shown by default for the entire Membase Server cluster. The information is aggregated from all the server nodes within the configured cluster for the selected bucket.
The standard Data Buckets monitor screen is shown below. Each individual graph is updated in real-time according to the selected time interval.
The following functionality is available through this display, and is common to all the graphs and statistics display within the web console.
Bucket Selection
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.
Server Selection
The Server Selection option enables you to enable the display for an individual server instead of for the entire cluster. You can select an individual node, which displays the Section 1.3, “Server Monitoring” for that node. Selecting All Server Nodes shows the Section 1.2, “Bucket Monitoring” page.
Interval Selection
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.
Statistic Selection
All of the graphs within the display updatre 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 view the statistics on each individual server, instead of the default view which shows the entire cluster information for a given statistic.
