UptimeBar is an all-in-one server monitoring tool meant for Shared, VPS or Dedicated servers, although it was created to monitor multiple VPS nodes inside one interface, with very little set-up time.
With an easy-to-use automatic installer, all you need to edit is one file with your website and database details, and the installer will do the rest. It creates all the database tables you will need, as well as the user that you will login to UptimeBar with.
After setting up your cron job to run every 5 minutes, TinyMTR will take care of all your logging for you, and will start reporting the statistics after just the first 5 minutes. Showing you the ping result times and the status of the website itself. As well as the memory and load status of the website if you wish to include it.
