Listing Node Services

reference

The services running on a specific node can be listed, with their respective port numbers, by means of the GET /pools/default/nodeServices method and URI.

HTTP methods and URI

GET /pools/default/nodeServices

Description

Couchbase services (Data, Query, Index, Search, Analytics, and Eventing) and other essential processes are associated with specific port numbers. A complete list of the associations is provided in Couchbase Server Ports.

The services and processes currently occupying these port numbers on a given node are listed by means of the GET /pools/default/nodeServices method and URI.

Curl Syntax

curl -v -X GET -u [admin]:[password]
http://[ip-address]:8091/pools/default/nodeServices

Responses

Success gives the status 200 OK, and returns an object containing a list that includes all services and their port numbers, plus any alternate addresses and port numbers that may have been configured.

If an incorrect primary address is specified, a Could not resolve host: <host-number> error message is displayed.

If the URI is incorrectly specified, a 404 Object Not Found error is flagged.

Example

The following example pipes the returned object to the jq command, to facilitate readability:

curl -v -X GET -u Administrator:password \
http://10.143.192.101:8091/pools/default/nodeServices | jq

The displayed output is as follows:
