class Widgets::Load

The Load widget reads /proc/loadavg.

Such values read like +1.28 1.18 0.92 1/2076 771310+.

Where the first 3 values are the 5, 10 and 15m average loads.

The fourth value is the running and total tasks (separated by a slash).

The last value is the last pid.

By default the load widget formats these as +“load avg: #{@short} #{@mid} #{@long}”+.

However, when a block is given it is executed with all parameters.

It is executed like

options[:proc].call @short, @mid, @long, @running, @tasks, @last_pid

Example:

widget :load do |short, mid, long, running, tasks| "tasks: #{running}/#{tasks}" end
widget :load do |short| "5m avg: #{short}" end
