|
## 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.

|
| 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. |
