config

The config command, used by cbstats, returns configuration statistics on a specified bucket, on a specified node.

Description

The config command, used by cbstats, returns configuration statistics on a specified bucket, on a specified node.

Syntax

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

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.

The config command takes no command options.

Example

The following call returns configuration statistics on the travel-sample bucket, for the specified node.

10.142.181.101:11210 -b travel-sample \
-u Administrator -p password \
config

If successful, the command returns the following output. (Note that the ep_magma statistics are returned on Couchbase Server Enterprise Edition only.)
