Increase log verbosity

The Sqreen agent can log messages to a text file. These messages contain warnings about possible abnormal behavior and describe some actions the agent is executing.

Two values in Sqreen configuration control the logging:

Env variable name Role Default value Options
SQREEN_LOG_LOCATION Specify a custom file to write Sqreen logs The terminal Custom filepath

The INFO level is verbose but still suitable for production environments. Only use DEBUG for short periods of time due to the amount of data it generates.

Sqreen is not showing any protected requests but my application has traffic

Ensure the main module of your application starts with the following code:


Sqreen does not show anything under the 'DB requests' field

This can come from two issues: The application does not have the Sqreen module as the first module required. Ensure that require('sqreen') is the first statement executed by the application. Sqreen does not support the database. Please contact us to discuss this topic.

Sqreen does not log in

Run the troubleshooting script sqreen-check-network:

At the root of the project, run the following:

$ node ./node_modules/.bin/sqreen-check-network
Or if using a proxy:
$ node ./node_modules/.bin/sqreen-check-network -p <proxy_url>

The script tries to reach Sqreen server to ensure it's accessible.
