ZooKeeper metrics

Many of the collected metrics from ZooKeeper entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability for information about entity types in SolarWinds Observability.

The following table lists some of the metrics collected for these entities. To see the ZooKeeper metrics in the Metrics Explorer, type zookeeper. in the search box.
