VPDB uses a couple of services.
Raygun is a crash reporter. It is configured in the
settings, more precisely at vpdb.services.raygun.
Rollbar is another crash reporter. Like Raygun, it's configured in the
settings at vpdb.services.rollbar.
Sqreen provides several security-related features.
You can enable Sqreen by setting the SQREEN_ENABLED environment variable to
something truthy. Other configurations such as SQREEN_TOKEN are documented
here.
