Checkmate is a self-hosted infrastructure monitoring application that gives administrators a central web interface for tracking service availability, incidents, response times, and server health.
It monitors websites and network services, stores historical data for analysis, and can be extended with the optional Capture agent to collect hardware and system metrics such as CPU, memory, disk, network, and temperature from remote machines.
This is free and open source software.
Key Features
- Monitors websites and network endpoints with uptime, ping, TCP port, SSL, and JSON query checks.
- Supports infrastructure monitoring for servers, including CPU, memory, disk, network, and temperature metrics through the Capture agent.
- Includes Docker monitoring for tracking container health and resource usage.
- Provides page speed monitoring with performance data and historical response time charts.
- Offers incident tracking, scheduled maintenance, and public status pages for communicating service health.
- Sends notifications through e-mail, webhooks, Discord, and Slack.
- Supports game server monitoring.
