| > 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. | |
