Metricset fetches the data returned by the mntr
admin keyword. It exposes the following metrics:
-
zookeeper.mntr.hostname
: ZooKeeper hostname. -
zookeeper.mntr.approximate_data_size
: Approximate size of ZooKeeper data. -
zookeeper.mntr.latency.avg
: Average latency between ensemble hosts in milliseconds. -
zookeeper.mntr.ephemerals_count
: Number of ephemeral znodes. -
zookeeper.mntr.followers
: Number of followers seen by the current host. -
zookeeper.mntr.max_file_descriptor_count
: Maximum number of file descriptors allowed for the ZooKeeper process. -
zookeeper.mntr.latency.max
: Maximum latency in milliseconds. -
zookeeper.mntr.latency.min
: Minimum latency in milliseconds. -
zookeeper.mntr.num_alive_connections
: Number of connections to ZooKeeper that are currently alive. -
zookeeper.mntr.open_file_descriptor_count
: Number of file descriptors open by the ZooKeeper process. -
zookeeper.mntr.outstanding_requests
: Number of outstanding requests that need to be processed by the cluster. -
zookeeper.mntr.packets.received
: Number of ZooKeeper network packets received. -
zookeeper.mntr.packets.sent
: Number of ZooKeeper network packets sent. -
zookeeper.mntr.pending_syncs
: Number of pending syncs to carry out to ZooKeeper ensemble followers. -
zookeeper.mntr.server_state
: Role in the ZooKeeper ensemble. -
zookeeper.mntr.synced_followers
: Number of synced followers reported when a node server_state is leader. -
zookeeper.mntr.version
: Version and build string reported. -
zookeeper.mntr.watch_count
: Number of watches currently set on the local ZooKeeper process. -
zookeeper.mntr.znode_count
: Number of znodes reported by the local ZooKeeper process.
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
