Mostro is a server monitoring service bringing usability and ease of setup to a world of complex, often critical problems.
Users can get a server fully monitored within seconds, with actionable insights for services such as MySQL, PostgreSQL, Memcache etc. out of the box, and hundreds of checks and triggers already configured with sensible defaults.
The shell-based agent is secure, open-source, lightweight and extensible, while the text-based, server-side configuration allows for an easy deploy accross infrastructures using tools like Ansible, Chef and Puppet. Users can write their own additional checks using in any language. Here's a simple example.
Made with Ruby on Rails, Sidekiq, Redis, InfluxDB and Bash.
