By default, the agent binds to 3 ports on Linux and 4 ports on Windows and OSX.
| Port | Description |
| 5000 | Exposes runtime metrics about the agent. |
| 5001 | Used to send commands from the agent CLI and GUI, and retrieve information from the running agent. |
| 5002 | Provides the GUI server on Windows and OSX. |
| 8125 | Used by the DogStatsD server to receive external metrics. |
If the above ports are occupied by another service instead of the Datadog agent,
you may encounter related port errors in the agent log,
or in the case of Windows, you may not be able to use the Datadog Agent Manager GUI,
or the agent may not start properly.
In the datadog.yaml file, remove the comments from each item as shown below,
change the ports from 5000/5001/5002 to other ports that are not occupied by another application,
and then restart the agent.
