This might come across as a silly question but is there any shell that will allow me to get the system information as the shell is active? What I mean is a shell like bash or similar that will show me the current cpu,memory, io and network usage at the top or anywhere but being parallel to the console. Something like:

---------------------------------
| CPU:3% I/O:4% Mem free: 1.5GB |
=================================
|                               |
|                               |
|                               |
| user@server ~ $: ls           |
| folder1 folder2 some_file1    |
| user@server ~ $:_             |
---------------------------------

I'm looking for something that is console only so that I can get its statistics from say an ssh session.

  • Why do you want this? – ewwhite May 24 '15 at 18:15
  • @ewwhite Because I need to keep an eye on the web-server on high-load and high-traffic times and keeping multiple ssh windows open with each running different tools is a bit inefficient. – ddrjm May 24 '15 at 18:27

    @ddrjm Watching a terminal for CPU and load information is also inefficient. Are you sure you're not looking for a simple monitoring/alerting solution? Something like Monit is very easy to install and is possibly the better way to keep track of these conditions. – ewwhite May 24 '15 at 18:34
  • @ewwhite Monit sounds great but is it secure as in, needing to auth and maybe go to a specific port to check the system? – ddrjm May 24 '15 at 19:04

Have a look at byobu - its customizable to your needs and also comes with a good default configuration.

  • Mind = blown. This might just be what I'm looking for. Can this be used via ssh? I'm currently running windows and this would help cut the number of putty windows down by a lot – ddrjm May 24 '15 at 18:29
  • @ddrjm byobu is a wrapper for screen / tmux and it can be used by ssh (if it runs on the remote host). – lgaggini May 25 '15 at 6:53
