Display live Linux system stats (memory, CPU, IO, etc) in a pretty web-page, with charts and everything.
Linux (and many other UNIXy operating systems) have a command line tool calledvmstat for monitoring system stats.
It looks like this (a new line is output every second showing the latest values):
$ vmstat 1procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----r b swpd free buff cache si so bi bo in cs us sy id wa3 0 43652 2742600 453820 2829164 0 0 1 10 0 0 6 1 93 01 0 43652 2742784 453820 2829164 0 0 0 0 3106 5701 11 1 87 00 0 43652 2742908 453820 2829164 0 0 0 0 3898 6703 11 2 87 01 0 43652 2743672 453820 2829164 0 0 0 32 3844 6708 11 2 87 02 0 43652 2743980 453820 2829164 0 0 0 80 4130 7164 11 2 87 0Useful, but fugly.
This is a tiny application that streams these stats over a WebSocket usingwebsocketd and charts themusingSmoothieCharts.
Why not? A handy little process to install on machines you care about.After building this for my own needs, I thought it would make a greatlittle demo.
And if you want to use it or hack on it yourself, here it is.
See./run script for instructions.
