CAT is a real-time application monitoring (APM) platform developed in Java at Meituan-Dianping, providing performance metrics, health status, and real-time alerting. It offers multi-language clients (Java, C/C++, Node.js, Python, Go) and deep integration with middleware frameworks.
Use cases
- monitor distributed java applications in real time
- distributed tracing across microservices
- real-time alerting on application metrics
- application performance monitoring apm
- collect and visualize system health metrics
- trace slow rpc and database calls
When to choose
- you need minute-level real-time monitoring with high throughput
- you run java-centric microservices and want deep middleware integration
- you want self-hosted apm with multi-language clients
When to avoid
- you prefer managed cloud apm solutions
- your stack is not java-centric and community clients lack support
- you need modern opentelemetry ecosystem compatibility
