> 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 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. |
