With ISA you can set an unlimited number of URLs to verify and a timer (from 5 to 60 seconds); also two control modes are availables: 'INET' (url is downloaded locally) and 'browser' (url is opened in a local browser page). First is the best to verify availability of a page.

Controls can be made manually or in automatic mode.

All programs activities are logged in two logs file, session log and global log. With the general log ISA can draw graphics of availability of selected url. Graphic is scaled in 10 seconds bar (vertically), with an 'x' to show faults and '°' to show times too longs; a '.' show a correct page availability. Graphic can be saved in jpeg format.

Graphic is not dinamic, so can be plotted only with data (global log) already saved on the hard disk. So, the best use is configure URLs, run program for some time, and after plot the graphic.
