Monitoring Linux Process
Collect and monitor basic information of processes on Linux systems, including CPU usage, memory usage, physical memory, IO, etc.
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. |
