+## Configuration Parameters
+
+|   Parameter Name    |                                                      Parameter Description                                                       |

+| Target Host         | The IPv4, IPv6, or domain name of the monitored endpoint. Note ⚠️: Do not include the protocol header (e.g., https://, http://). |
+| Task Name           | Identifies the name of this monitoring, ensuring uniqueness.                                                                     |
+| Port                | SSH port of the Linux system, default: 22                                                                                        |
+| Timeout             | Sets the timeout for the connection in milliseconds, default is 6000 milliseconds.                                               |
+| Reuse Connection    | Sets whether SSH connection is reused, default is false. When false, a new connection is created for each information retrieval. |
+| Username            | Username for the server.                                                                                                         |
+| Password            | Password for the server.                                                                                                         |
+| Process Name        | Name or part of the name of the process to be monitored.                                                                         |
+| Collector           | Specifies which collector to use for scheduling this monitoring.                                                                 |
+| Monitoring Interval | Interval for periodic data collection, in seconds. Minimum interval that can be set is 30 seconds.                               |
+| Tags                | Used for categorizing and managing monitoring resources.                                                                         |
+| Description         | Additional notes and descriptions for identifying this monitoring. Users can add remarks here.                                   |
+| Private Key         | Private key required for connecting to the server.                                                                               |
