I have been using Confio Ignite for about a year and half and it is wonderful. I tested many and this was the easiest to setup with virtually no overhead on the servers that I was monitoring. I did not have to install anything on my production servers. You can easily drill down into issues, right to the query causing the problems and see if it is a new problem or something that has been building over time. Tuning advice and the actual execution plan are just a click away. Trending analysis can go back a year depending on how you set it up. Alerts can be created to notify you of issues right away. It is just a great tool that becomes your best friend.
