# Configuration file of the Universal Profiling Agent
The Universal Profiling Agent can be configured using a configuration file. Specify the path to the configuration file using the CLI argument `-config`. The default path for the configuration file is `/etc/Elastic/universal-profiling/pf-host-agent.conf`.
The expected format of the configuration file is a plaintext file, where each line holds one option.
Example:
```
project-id: 73
secret-token: abc123
collection-agent: example.com:443
```

<warning>
  Command line arguments to the Universal Profiling Agent take precedence over environment variables, and environment variables take precedence over the configuration file.
