The "default" transaction explained
The transaction called "default" will appear in your projects monitoring for requests that have neither a transaction nor a script and are most likely requests from bots who are crawling for PHP scripts.
Examples are requests for phpMyAdmin or Wordpress login and admin pages when you don’t have phpMyAdmin or Wordpress installed. Depending on the PHP setup these are served as 404 responses from PHP-FPM and appear in Tideways.
Before the release of "tideways-daemon" version 1.6.30 all requests that used their script name as transaction name where also renamed to "default" if their HTTP status code was an error with 400 or above.
