Monitoring app
Lumen
Status: LiveUptime monitors, incidents, and alerts for the services you need to trust.
Lumen checks endpoints on a schedule, keeps a clear history of every run, and alerts the right people when something fails. It is Hollow’s monitoring app, with public status pages for the incidents customers need to see.
