.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Loadbars is a small script that can be used to observe \s-1CPU\s0 loads of several remote servers at once in real time. It connects with \s-1SSH\s0 (using \s-1SSH\s0 public/private key auth) to several servers at once and vizualizes all server CPUs and memory statistics right next each other (either summarized or each core separately). Loadbars is not a tool for collecting \s-1CPU\s0 loads and drawing graphs for later analysis. However, since such tools require a significant amount of time before producing results, Loadbars lets you observe the current state immediately. Loadbars does not remember or record any load information. It just shows the current \s-1CPU\s0 usages like top or vmstat does.

.IX Subsection "Config file support"
.PP
Loadbars tries to read ~/.loadbarsrc and it's possible to configure any option you find in \-\-help but without leading '\-\-'. For comments just use the '#' sign. Sample config:
.Sp
.RS 4
showcores=1 # Always show cores on startup
.RE
.PP
will always show all \s-1CPU\s0 cores. If you press the 'w' hotkey during program execution your config file will be overwritten using the current settings.
