Monitoring HBase RegionServer Monitoring

Collect and monitor common performance metrics for HBase RegionServer.

Protocol: HTTP

Pre-Monitoring Operations

Review the hbase-site.xml file to obtain the value of the hbase.regionserver.info.port configuration item, which is used for monitoring.

Configuration Parameters

Parameter NameParameter Description
Target HostThe IPV4, IPV6, or domain name of the monitored entity. Note ⚠️ Do not include the protocol header (e.g., https://, http://).
PortThe port number of the HBase regionserver, default is 16030, i.e., the value of thehbase.regionserver.info.port parameter
Task NameA unique name to identify this monitoring task.
Query TimeoutSet the connection timeout in ms, the default is 3000 milliseconds.
Collection IntervalThe interval time for periodic data collection in seconds, with a minimum interval of 30 seconds.
Probe Before AddingWhether to probe and check the availability of monitoring before adding new monitoring, only proceed with the addition if the probe is successful.
Description NoteAdditional notes to identify and describe this monitoring, users can add notes here.
