This plugin records the HTTP response status code for outgoing requests of an application.

When the amount of errors (5XX HTTP status codes) reaches a peak compared to the usual application traffic, this plugin triggers.

Such signal might be the first hint that an attacker has found an issue in your application and tries to exploit it.

Advanced details

At runtime, this plugin collects the number of 5XX HTTP responses and reports them back to Sqreen’s backend. This data is sent asynchronously every minute and doesn’t slow down applications.

On Sqreen’s backend, these metrics are aggregated in real time to detect peaks.
