Configuration parameter

Parameter Name	Parameter Help Description
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.

Username	SSH connection username, optional.
Password	SSH connection password, optional.
Collector	Configures which collector is used to schedule data collection for this monitoring.
Monitoring Period	The interval time for periodic data collection in seconds, with a minimum interval of 30 seconds.
Binding Tags	Used for categorized management of monitoring resources.
Description	Additional notes and descriptions for this monitoring, where users can make notes.
PrivateKey	The private key required to connect to the server.
PrivateKey PassPhrase	The password phrase used to encrypt the SSH private key. If the private key was generated with a passphrase, this field must be filled to decrypt and use the key for authentication.
Proxy Host	The address of the proxy server, supporting IPV4, IPV6, or domain name format. Required when using SSH jump host to access the target host.
Proxy Port	The port number of the proxy service, default is 22.
Proxy Username	The authentication username required to connect to the proxy server.
Proxy Username	The authentication password required to connect to the proxy server.
Proxy PrivateKey	The private key required to authenticate with the proxy server.
