Cabot

Cabot is a self-hosted application that keeps an eye on your digital services. It actively checks the status of websites, monitors Graphite metrics for unusual activity, and watches Jenkins jobs. If something goes down or a performance metric crosses a dangerous threshold, Cabot is designed to notice it immediately and send out an alert.

The tool works by letting you define specific checks for different parts of your infrastructure. You can group these checks into logical 'services' or physical 'instances' to create organized dashboards. What makes Cabot practical is its range of alerting options; it can notify your team of problems through phone calls, SMS, email, or Hipchat messages, ensuring the right people know about an issue as soon as it happens.

This tool is built for developers and system administrators who need a straightforward, self-controlled alternative to SaaS monitoring services. It's ideal for teams that want to monitor internal services not exposed to the public internet, keep alerting data in-house, or have specific needs that off-the-shelf cloud monitors can't meet.
