Vigil

Microservices Status Page. Monitors a distributed infrastructure and sends alerts (Slack, SMS, etc.).

Vigil is an open-source Status Page you can host on your infrastructure, used to monitor all your servers and apps, and visible to your users (on a domain of your choice, eg. status.example.com).

It is useful in microservices contexts to monitor both apps and backends. If a node goes down in your infrastructure, you receive a status change notification in a Slack channel, Email, Twilio SMS or/and XMPP.
