# Couchbase node metricset
The Couchbase `node` metricset collects data from Couchbase pools Rest API `http://couchbasehost:8091/pools/default` and creates an event for each node in the cluster.
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.

## Fields

For a description of each field in the metricset, see the [exported fields](https://www.elastic.co/docs/reference/beats/metricbeat/exported-fields-couchbase) section.
