This module creates list of computers, which are going to be pinged periodically. List is created by pressing the button Add. A dialog opens, prompting you for monitored computer address, ping period and other completive information for ping. After you enter the values and click OK, the record is added to the table of monitored computers. Monitoring is started by selecting appropriate record in the table and pressing Start. In the bottom part of the window, there will be appearing results of each ping. You can switch on graphical representation too. Graph displays always one ping as one graph peak and because graph scrolls to left, you can see response time of a monitored station in the past and optically compare it.
