Configuration

[theldoria]

The visualization line should be configurable.

On my desktop, for example, it kames no sense to show BAT state.

Also I would like to plug in my own value providing functions.

I'm thinking of something like this :

(define-symon-monitor symon-linux-battery-monitor
  :index       "BAT"
  :history     50            ; last 50 values are drawn as a sparkline
  :upper-bound 100           ; upper-bound of sparkline is 100(%)
  :unit        "%"
  :setup       (require 'battery) ; `symon-linux-battery-monitor' requires `battery.el'
  :cleanup     nil
  :value       (and battery-status-function
                    (read (cdr (assoc ?p (funcall battery-status-function)))))
  :annotation  (and battery-status-function
                    (cdr (assoc ?L (funcall battery-status-function)))))

(setq symon-monitors '(symon-linux-memory-monitor
                       symon-linux-battery-monitor
                       symon-linux-cpu-monitor))
;; => "MEM:xx% BAT:yy% CPU:zz%"

That looks perfect. I was just coming here to request something similar. It would be great to factor out the different performance checks and allow the user to define their own.

Just looking at this a bit more. You may wish to include an optional lower bound and the ability to turnoff the sparkline for some metrics. Perhaps by setting history to 1?

I think all properties should be optional and users can turn-off sparklines by omitting :history property.
