id: hbase_regionserver title: Monitoring HBase RegionServer Monitoring sidebar_label: HBase RegionServer Monitoring keywords: [Open-source monitoring system, Open-source database monitoring, RegionServer monitoring] Collect and monitor common performance metrics for HBase RegionServer. Protocol: HTTP Review the `hbase-site.xml` file to obtain the value of the `hbase.regionserver.info.port` configuration item, which is used for monitoring. | Parameter Name | Parameter Description | | - | -- | | Target Host | The IPV4, IPV6, or domain name of the monitored entity. Note Do not include the protocol header (e.g., https://, http://). | | Port | The port number of the HBase regionserver, default is 16030, i.e., the value of the`hbase.regionserver.info.port` parameter | | Task Name | A unique name to identify this monitoring task. | | Query Timeout | Set the connection timeout in ms, the default is 3000 milliseconds. | | Collection Interval | The interval time for periodic data collection in seconds, with a minimum interval of 30 seconds. | | Probe Before Adding | Whether to probe and check the availability of monitoring before adding new monitoring, only proceed with the addition if the probe is successful. | | Description Note | Additional notes to identify and describe this monitoring, users can add notes here. | All metric names are directly referenced from the official fields, hence there may be non-standard
