A simple Sinatra/SQLite based status (node availability) board application

Statusboard

Statusboard is a simple Sinatra/SQLite powered application to track availability of remote nodes. The remote node can be any application that responds with 200/4xx (up/down) HTTP status.

Application currently supports:

• Calculation of uptimes of individual nodes and total.
• Retrieval of RSS feed from any external service explaining the reason of the downtime.
• Viewing the past uptimes defined by a date range (date picker).
• Sending a "panic" email when there is a downtime.

Note: Downtime means when all nodes are down at a given time.
