# ZooKeeper server metricset
`server` Metricset fetches the data returned by the `srvr` admin keyword.
- `zookeeper.server.connections`: Connections established by the server
- `zookeeper.server.latency.avg`: Average latency of the server
- `zookeeper.server.latency.max`: Max latency reached by the server
- `zookeeper.server.latency.min`: Minimum latency that has been reached by the server
- `zookeeper.server.mode`: Server mode
- `zookeeper.server.node_count`: Total number of nodes
- `zookeeper.server.outstanding`: Outstanding
- `zookeeper.server.received`: Received requests to the server
- `zookeeper.server.sent`: Requests sent by the server
- `zookeeper.server.version_date`: Date of the Zookeeper release in use
- `zookeeper.server.zxid`: Original value of the Zookeeper transaction ID
- `zookeeper.server.count`: Total transactions of the leader in epoch
- `zookeeper.server.epoch`: Epoch value of the Zookeeper transaction ID

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/2452/reference/beats/metricbeat/exported-fields-zookeeper) section.
