Retrieving Cluster Information
- reference
Cluster information is retrieved with GET /pools
HTTP method and URI.
Syntax
Curl request syntax:
curl -u [admin]:[password] http://[localhost]:8091/pools
HTTP request syntax:
GET /pools Host: localhost:8091 Authorization: Basic xxxxxxxxxxxxxxxxxxx Accept: application/json X-memcachekv-Store-Client-Specification-Version: 0.1
A pool represents computing resources (machines, memory, CPU, disks) that are used to host Couchbase buckets.
Couchbase Server clusters currently support only a single pool named default
.
While the specified server is a member of one cluster, a server can also be aware of other pools. The Client-Specification-Version is optional in the request, but advised. It enables implementations to adjust representation and state transitions to the client, if backward compatibility is desirable.
HTTP method and URI
One of the first ways to discover the URI endpoints for the REST API is to find the available clusters.
To find the available clusters, provide the Couchbase Server IP address, port number, and append /pools
.
GET /pools
Example
To send a request for cluster information using curl:
curl -u Administrator:password http://10.5.2.117:8091/pools
Response
Couchbase Server returns only one cluster per group of systems and the cluster typically has a default name.
Couchbase Server returns the build number for the server in implementationVersion
and the specifications supported are in componentsVersion
.
The corresponding HTTP response contains a JSON document describing the cluster configuration.
