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 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 thehbase.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. |
