# Environment variables to configure the Universal Profiling Agent
The Universal Profiling Agent can be configured with environment variables.
<warning>
  Command line arguments to the Universal Profiling Agent take precedence over environment variables, and environment variables take precedence over the configuration file.
</warning>


| Environment variable                | Example                                                                | Description                                                                                                                                                                                                                                                                                          |
