The all command provides information on memory, queues, persistence, and vBuckets.

Description

The all command, used by the cbstats utility, provides information on memory, queues, persistence, and vBuckets.

Syntax

cbstats <host>:<port> [common options] all

The host must be the hostname or IP address of a node within the cluster. The port must be 11210. The common options must include a username and password, and a reference to a bucket defined on the cluster. For a complete list of common options, see the table provided on the introductory page for cbstats.

This command accepts no command options.

General Output

This following table describes some of the statistics returned by cbstats all. Note that ep stands for eventual persistence, and simply refers to the Data Service.
