Is anyone you interested in a GUI process monitoring utility?
Yes and no. The original process model of Richie/Kernighan UNIX has become lost. Back then the model was lightweight, short lived processes. The shell was simply a dispatcher. The contrast was with the big heavy long lived processes on IBM machines. The cost of starting a process under UNIX was negligible and there was no 'transient process area' concept as in the 'DOS" version of IBM and other OSs that followed that concept. An implication of this model meant that there were no processes worth monitoring because they didn't live long enough. That was then, this is now. But then again, why? Many of the long lived processes are dispatchers. CUPS is a good example of the change in how print systems have changed since then, but it is really a dispatcher. Yes, we have long lived: Thunderbird, Firefox ... perhaps you spend a lot of time editing in a .doc or .xls My attitude is that I want to look at various aspects. I have an xterm that that runs 'iftop' to tell me where the network & bandwidth goes. That gives me a UID I use with other tools to drill down. I have an xterm that that runs 'vmstat' with a parameter list that tells me about memory, swap and disk activity in gross terms and rates. That too might cause me to drill down using other tools. OK, on my system (15.2) what eats performance is heavy SWAP use. My point here is that I am looking at DYNAMICS and CHANGES in different aspects and those top level tools let me drill down using other tools. I'm looking at hoe LINUX works, not an IBM OS. You mention 'top'. Well I use 'htop'. And I can choose what I want to look at, sort-by and prioritise. But that's not where I start, I end up there as a result of other tools. Oh, and there's logs. So I look at 'procno' and I'm wildly UN-impressed. It's the sort of 'flashing lights' display that will look good in a movie or in a presentation for technically ignorant management. -- “Reality is so complex, we must move away from dogma, whether it’s conspiracy theories or free-market,” -- James Glattfelder. http://jth.ch/jbg
