Nodewatcher

This program monitors the status of a Lightning Node and sends an alert if the node is unsynced or another issue is detected. It also and makes static channel backups.

Rationale

If lightning node is offline, channel parter could force close channels and steal the money on that channel. Routing nodes are also monitored for uptime by their peers and payment routing is deprioritized for less reliable nodes.
