> Collect monitoring data for general performance metrics of Hbase Master.

**Protocol: HTTP**

## Pre-monitoring steps

Check the `hbase-site.xml` file to obtain the value of the `hbase.master.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 peer. Note: without protocol header (e.g., https://, http://).                                                                   |
| Port                | The port number of the Hbase master, default is 16010. That is, the value of the`hbase.master.info.port` parameter.                                                              |
| Task Name           | The name identifying this monitoring, which needs to be unique.                                                                                                                  |
| Query Timeout       | Set the connection timeout in ms, the default is 3000 milliseconds.                                                                                                              |
| Collection Interval | The periodic collection interval for monitoring data, in seconds, with the minimum allowable interval being 30 seconds.                                                          |
| Probe               | Whether to probe and check the availability of monitoring before adding new monitoring, and proceed with the addition or modification operation only if the probe is successful. |
| Description         | Additional notes and descriptions for this monitoring, users can add notes here.                                                                                                 |
