Nova Software monitors the websites of the 500 most active domains in the world‡ with the latest release of appchkr. The links above display the current up/down status snapshot for those 500 sites, the uptime history graph and uptime summary (performance) reports for period shown, the recent alerts, if any, and the real-time scan log. These demonstration pages update to the latest ones after each scan of the sites, which can be seen while watching the pages in your browser.
A very short timeout has been choosen for the monitoring so as to show occasional failure-to-connect for some of the slower sites, due to network or server congestion, redirects, or other causes, and thus to illustrate monitoring of a less-than-perfect system. Click on the alerts link to see the latest alerts corresponding to such events. All of the factors controlling this behavior are fully configurable in the Appchkrs, with well-thought-out default values eliminating any need for user action outside of exceptional cases.
A small number (~20) of very erratically-responding, private, or blocked domains have been set to 'nochecking', for clarity, and to illustrate this feature of the Appchkrs.
