vigil

Monitor distributed infrastructure and send 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). 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.
