It has all I need for monitoring my websites! As an individual webmaster who runs many sites myself - this was one of those utilities that made me look like someone with knowledge beyond their years (or at least experience)! When we had issues where multiple servers were affected by downtime or other problems affecting our site(s), there would be no central place from which everyone could see if anything went wrong so troubleshooting became very difficult as well time consuming. So far things have been better but still not perfect since they do seem slow sometimes compared some more professional tools out there!! But overall great stuff here; just make sure your requirements align w/ theirs before jumping into any commitments because while free trial may work fine initially its hard going back once paid subscription comes up unless willing & able pay upfront without reservation. ! Monitoring performance across several server environments using various protocols / technologies including HTTP2 etc., ability to use custom.
