Recently in Loadbars Category
Loadbars v0.3.0 just has been released. Whats new? Not much but good things:
Mon Dec 26 14:46:25 CET 2011
* Releases v0.3.0
* Peak CPU load is not displayed by default anymore. User 'p' command or
the --togglepeak 1 startup option.
* Peak CPU load is now also displayd in text format (marked as pk)
* New option --cluster which brings rudimentary ClusterSSH config file
support. E.g. './loadbars --cluster server' reads cluster server from
the /etc/clusters file.
Sa 6. Aug 22:04:15 CEST 2011 * Released v0.2.0 (new major version) * No interactive CLI shell anymore but instead hotkeys for the SDL interface (press h and see). * Bugfixes (E.g. Loadbars does not hang anymore after typing commands) * Major code refactoring
Loadbars is a small Perl script which can be used to observe CPU loads of several remote servers at once in real time. It connects per SSH (using SSH public/private key auth) to several servers at once and vizualizes all server CPUs (summarized or each core separate) right next each other. Loadbars IS NOT the tool for collecting CPU loads and drawing graphs (per hour, day, week, month) for later analysis. There are enough other tools which can accomplish this (e.g. SNMP / RRDtool). However, those tools need some minutes until the first graphs are drawn. So Loadbars can be used to observe the current real time state in real time without waiting a few minutes first. Loadbars does not remember / historicize any load informations. Its just showing the current CPU usages like top or vmstat does.
