# Telemetry By default, Cortex sends anonymous usage data to Cortex Labs. ## What data is collected? If telemetry is enabled, events and errors are collected. Each time you run a command an event will be sent with a randomly generated unique CLI ID and the name of the command. For example, if you run `cortex get`, Cortex Labs will receive an event of the structure `{id: 1234, command: "get"}`. In addition, the operator sends heartbeats that include cluster metrics like the types of instances running in your cluster. ## How do I opt out? If you'd like to disable telemetry, modify your `~/.cortex/cli.yaml` file (or create it if it doesn't exist) and add `telemetry: false` before spinning up your cluster. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
