By default, the Cortex runtime logs all requests and responses. These logs appear in the app dashboard and are useful for debugging and monitoring. Disable them when privacy, security, or performance requires it.

​
Controlling Logs

Two settings control logging behavior in the Cortex runtime:
  • DISABLE_REQUEST_LOGS - When enabled, prevents logging of incoming request data
  • DISABLE_RESPONSE_LOGS - When enabled, prevents logging of response data from your app
These settings only affect the default Cortex runtime. If you are using a custom runtime, you will need to handle logging behavior in your own server implementation.

​
Configuration

Configure these settings as secrets at either the app or project level:
  1. Navigate to your project dashboard
  2. Go to the “Secrets” section
  3. Add one or both of the settings as a key with a value of "true" to disable the corresponding logs
Setting the value to anything other than true (or leaving it undefined) will keep logging enabled, which is the default behavior.

​
Use Cases

Common reasons to disable logs:
  • Processing sensitive data: If your app processes personal or sensitive information that shouldn’t be stored in logs
  • Observability optimization: For high-throughput apps where logging adds unnecessary overhead making it difficult to monitor your app

​
Example

To disable both request and response logging, add the following secrets to your app:
KeyValue
DISABLE_REQUEST_LOGStrue
DISABLE_RESPONSE_LOGStrue
Secrets are loaded on container startup. After updating a secret, restart the app container for the change to take effect.
