 loadbars - A small and humble tool to observe server loads


 Tested platforms
 This version of loadbars has only been tested on Debian GNU/Linux

 I like flying elephants
 For any startup params help check out --help on command line or 'h'
 during program execution.

 A few examples however
 loadbars --extended 1 --showcores 1 --height 300 --hosts localhost

 loadbars --hosts localhost,server1.example.com,server2.example.com

 loadbars --cluster foocluster (foocluster is in /etc/clusters

 More examples, using shell expansion
 loadbars servername{01,02,03}.example.com

 loadbars servername{01..50}.example.com --showcores 1

 Loadbars is a small script that can be used to observe CPU loads of
 several remote servers at once in real time. It connects with SSH (using
 SSH 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 CPU 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 CPU usages like top or vmstat does.

 CPU stuff
 st = Steal in % [see man proc] (extended), Color: Red

 gt = Guest in % [see man proc] (extended), Color: Red

 sr = Soft IRQ usage in % (extended), Color: White

 ir = IRQ usage in % (extended), Color: White

 io = IOwait cpu sage in %, Color: Purple

 id = Idle cpu usage in % (extended), Color: Black

 ni = Nice cpu usage in %, Color: Green

 us = User cpu usage in %, Color: Yellow, dark yellow if to>50%, orange
 if to>50%

 sy = System cpu sage in %, Color: Blue, lighter blue if >30%

 to = Total CPU usage, which is (100% - id)

 pk = Max us+sy peak of last avg. samples (extended)

 1px horizontal line: Maximum sy+us+io of last 'avg' samples (extended)

 Memory stuff
 Ram: System ram usage in %, Color: Dark grey

 Swp: System swap usage in %, Color: Grey

 Network stuff
 Rxb: Incoming (received) traffic in %, Color: Light green, normal green
 if >100% while using low netlink reference. Bar comes from top and is
 half width.

 Txb: Outgoing (transmitted) traffic in %, Color: Light green, normal
 green if >100% while using low netlink reference. Bar comes from bottom
 and is half width.

 When network bar is red: The interface does not exist on the specific
 remote host.

 Config file support
 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:

 showcores=1 # Always show cores on startup

 will always show all CPU cores. If you press the 'w' hotkey during
 program execution your config file will be overwritten using the current
