Monitoring

Simple monitoring tool with web application written in Go.

Features

• Very lightweight
• Simple
• CSRF tokens
• Thresholds
• Low interval checking
• Acknowledging
• Notifications (e.g. Telegram)
• Action handling
• Embed functionality (for example in Grafana)
• Protection against nuclear bombs and zombie apocalypses

Service checking and notifying

Uses JSON file(s) instead of a database such as MySQL! Nothing can break checking except purposefully human failure. Even if you delete the json file containing service checks, monitoring will still continue running!
