Monitor Your Sites and Servers
Central to Simon is the Monitor window. It enables you to see at a glance the current status of all of your monitored websites, servers, and applications. In addition to a colorful status icon and up-time percentage, the tests list displays how long ago the last change and failure occurred, and when the next check will occur. But that's not all. This window also displays further statistics about the tests, and a log showing recent activity, including when tests start checking, and the various steps during the check (starting, stopping, service result, each filter, notifications, etc), plus other actions on tests, e.g. editing, pausing, etc. It also has logs of checks (including the check duration), changes (including the text that changed), and failures (including the error description).
