| ## 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. | |
