The ability to monitor both applications as well as servers very easily, it's also super easy of configuring rules for alerts/notifications in case something happens! It has some quirks but nothing too serious really! I haven't found anything that would dislike about this software so far! If you are looking into real-time application logging with notifications then go ahead give this one try - no regrets at all!! Monitoring logs (both server side & client sided) helps us identify where issues may be coming from or what exactly might have caused them if any such issue was detected.
