By default, Python Agent and Java proxy communicate with each other using Inter-Process Communication (IPC).
However, using Transmission Control Protocol (TCP) communication is beneficial in these scenarios:
- When you want the Java proxy and Python Agent to run over different host operating systems.
- In containers (such as Docker and Kubernetes), where mounting the same volume for all the containers is possible but not recommended.
To enable TCP communication, set tcp-comm-port to a valid port. The Python Agent and Java proxy can now communicate using TCP rather than IPC.
The Java proxy listens to the incoming connection requests from agents over the APPDYNAMICS_TCP_COMM_PORT. The communication occurs for every agent over these two unique ports:
- Reporting port
- Request port
These ports can be set by either the agent or the proxy.
TCP Mode Configuration - Environment Variables
For cfg file versions of the environment variables, see Python Agent Settings.
This table lists the TCP mode configuration environment variables:
Environment Variable Name | Description |
|---|---|
|
|
APPDYNAMICS_TCP_COMM_PORT |
|
APPDYNAMICS_TCP_PORT_RANGE (Proxy only) | The port range over which the proxy allocates ports to communicate with the agents. |
APPDYNAMICS_TCP_REPORTING_PORT (Agent only) |
|
APPDYNAMICS_TCP_REQUEST_PORT (Agent only) |
|
