Review on YMOR Ymonitor by Jay Williams

The ability to monitor multiple servers in one dashboard, which is very helpful for troubleshooting issues that are impacting an entire server farm at once (rather than having to go into each individual machine). It's not perfect - sometimes it can be difficult to interpret large graphs with many different colors or lines. Sometimes you have to click through screens to find what you're looking for; this makes it somewhat less efficient. I use it primarily as a monitoring tool for our web application infrastructure. We've been able to see where we need to focus attention most quickly.
