What good tools can I use to monitor IIS. What is included seems to be not as useful as I'd like. I realize I can add performance counters; those don't tell me very much; it's just a collections of properties that are plugged into a generic graphing tool.
I have problems with old legacy applications hanging and various and sundry other things. Also, when I need to get basic information like how many connections I have in IIS and their details I don't know what to do. I've googled extensively and I cannot find much. I find some log parsers, but I want real time. I found some commerical tools that don't really seem quite what I want, besides I'd like to find something free. This is very basic stuff that is pretty easy to get in Apache. I found IISTracer but I am a bit skeptical of it; I did install and try it out. Is there anything else? Some of these legacy applications are classic ASP so just a CLR Profiler isn't what I'm looking for, although those are handy.
EDIT: Is IISTracer really the only tool like this out there for IIS?
