|---|---|
| Monitored Host | The IPV4, IPV6, or domain name of the host being monitored. Note ⚠️ No protocol header (e.g., https://, http://). |
| Task Name | The name that identifies this monitoring, which must be unique. |
| Port | The port provided by Linux SSH, default is 22. |
| Timeout | Sets the connection timeout in milliseconds, default is 6000 ms. |
| Connection Reuse | Sets whether SSH connections are reused, default is :false. If false, a new connection is created each time information is retrieved. |
