Couchbase Server incorporates a range of statistics and user interface available through the Data Buckets and Server Nodes that shows overview and detailed information so that administrators can better understand the current state of individual nodes and the cluster as a whole.
The Data Buckets page displayed a list of all the configured buckets on your system (of both Membase and memcached types). The page provides a quick overview of your cluster health from the perspective of the configured buckets, rather than whole cluster or individual servers.
The information is shown in the form of a table, as seen in the figure below.
The list of buckets are separated by the bucket type. For each bucket, the following information is provided in each column:
Bucket name is the given name for the bucket. Clicking on the bucket name takes you to the individual bucket statistics page. For more information, see Section 6.3.3, “Individual Bucket Monitoring”.
RAM Usage/Quota shows the amount of RAM used (for active objects) against the configure bucket size.
Disk Usage shows the amount of disk space in use for active object data storage.
Item Count indicates the number of objects stored in the bucket.
Ops/sec shows the number of operations per second for this data bucket.
Disk Fetches/sec shows the number of operations required to fetch items from disk.
Clicking the button opens the basic bucket information summary. For more information, see Section 6.3.2, “Bucket Information”.
