# Docker memory metricset
The Docker `memory` metricset collects memory metrics.
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/elastic/docs-builder/docs/2844/reference/beats/metricbeat/exported-fields-docker) section.
Here is an example document generated by this metricset:
