That's a cool idea. So if I understand you correctly you might see some sort of total line at the bottom? I can always add to my wish list but no promises. But I think I may also have a solution if you don't mind doing a little extra work on your own ;) btw - can I assume you've installed readkey so you can change sort columns with the arrow keys?
If you run colmux with --noesc, it will take it out of full screen more and simply print everything as scrolling output. If you then also include "--lines 99999" (or some big number) it will print all the output from all the remote systems so you don't miss anything. Finally you can pipe the output through perl, python, bash, or whatever your favorite scripting tool might be and do the totals yourself. Then whenever you see a new header fly by, print the totals and reset the counters to 0. You could even add timestamps and maybe even ultimately make it your own opensource project. I bet others would find it useful too. -mark On Thu, Jun 18, 2015 at 9:30 PM, Saurabh Agrawal <[email protected]> wrote: > Greetings, > > I am evaluating various system monitoring tools to use one to monitor my > hadoop cluster. > One of the tools I am impressed by is collectl.
