we want to have the ability to observe processes Out-Of-The-Box (each inexpensive tool supports this function!). Im miss a wizard where I can select the process(es) and the parameter to watch. The minimum is CPU and memory for a process. Next I could have imagined: threads, handles, I/O for read/write, I/O latency, ...
For us, this feature is very important because we can thus early detection of bottlenecks. Thus we have the opportunity to take timely measures. For example, through the purchase of additional hardware.
Also we can see if some software update consume more memory or cpu resources or if we have a memory leak.
