 - Category: The category of the asset, select `Machine`.
 - Protocol: The protocol of the asset, select `RDP`.

+- Endpoint: Unlike public assets, the endpoint needs to be filled in with the application address of the private network.
+  If you want to use SSH or RDP to connect to the host, enter 127.0.0.1
+- Port: The port of the application in the intranet machine. Port 3389 is used by RDP and 22 by SSH by default. If you

 ## Deploy Casvisor agent
 
-Casvisor agent is the same as Casvisor server, just deploy Casvisor in your intranet machine and start it with the same `conf/app.conf` as the server.
+You need to deploy a Casvisor on the host to which you are connected in the intranet. As mentioned in the previous chapter,
+when the casvisor starts, it connects to the database to check whether the current hostname is the name of an asset, and
+if so, it starts in agent mode. So the must configurations in the agent Casvisor `conf/app.conf` are below:
+
+```ini
+httpport = 19000
+driverName = 
+dataSourceName = 
+dbName = 
+gatewayEndpoint = door.casvisor.com:19100
+```
+
+It is **recommended** that you can copy the same configuration file `conf/app.conf` in the server Casvisor directly.
