In PHP >= 7.4 you can get error messages like "Unknown process state 'Getting request information'" in php-fpm_exporter.
And indeed, "Getting request information" is unknown, as php-fpm_exporter is checking for "Getting request informations" (note the wrong plural "s"), which was correct for PHP < 7.4
This was changed in PHP >= 7.4 with php/php-src@84b195d
FPM_REQUEST_INFO changed from
Getting request informations
toGetting request information
in PHP 7.4See
[FPM_REQUEST_INFO] = "Getting request information"
