                $obfuscator = new \kbATeam\GraylogUtilities\Obfuscator();
                //Replace the value of all keys named 'password' with 'xxx'.

                $obfuscator->setObfuscationString('xxx');

                return json_encode(
                    $obfuscator->obfuscate($_POST),
                    JSON_PRETTY_PRINT
