The ease of use. It's been easy for us so far to get data in real time with this tool, especially since it integrates well into our Jenkins environment. I would like more detailed information about how much CPU each instance was using (though that can be difficult to parse out from the dashboard). We have used other tools before but we couldn't pull up the same level of detail or integration as easily with those products. This has allowed me to identify areas where our applications are performing poorly during certain times of day and helps me make changes to improve overall application performance.
