The latest fop2 version can pause with reason. Upgrade fop2 and you will have that feature, you can uncomment the proper section in /var/www/html/fop2/js/presence.js... also using the presence pause plugin will set a pause with reason in queue_log that can be reported with asternic. Everything is there, you just need to use the latest fop2 and configure it appropriately.
Best regards,
