# Advanced configuration for Elastic Universal Profiling
After completing the steps in the [Get started](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/get-started-with-universal-profiling) documentation, you may need to continue to more advanced configuration for your deployment. See the following sections for more information:
- [Tag data for querying](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/tag-data-for-querying): Tag data collected by the Universal Profiling Agent into multiple logical groups so they can be queried in Kibana.
- [Add symbols for native frames](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/add-symbols-for-native-frames): Push symbols to your cluster so you can see function names and line numbers in traces of applications written in programming languages that compile to native code (C, C++, Rust, Go, etc.).
- [Use a proxy](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/use-proxy-with-universal-profiling-agent):  Set up an HTTP proxy if your infrastructure Universal Profiling Agent installation needs one to reach Elastic Cloud.
- [Override kernel version check ](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/override-kernel-version-check): Configure the Universal Profiling Agent to bypass the kernel version compatibility check.
- [Environment variables for the Universal Profiling Agent ](https://www.elastic.co/elastic/docs-builder/docs/3016/solutions/observability/infra-and-hosts/environment-variables-to-configure-universal-profiling-agent): Configure the Universal Profiling Agent using the environment.

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

The Universal Profiling Agent accepts the following CLI arguments:

| CLI argument               | Type       | Example                                                       | Description                                                                                                                                                                                                                                                                                          |
