Glowroot: Open Source Java APM
Glowroot is an open source Java Application Performance Monitoring (APM) tool. It is used to monitor, profile and diagnose performance issues in Java applications in real-time. Glowroot is lightweight, easy to use, and provides detailed monitoring data to quickly find and fix performance bottlenecks.
What is Glowroot?
Glowroot is an open source Java Application Performance Monitoring (APM) tool for diagnosing performance issues in Java applications. It is designed specifically for monitoring Java applications in production environments with minimal overhead.
Some key features of Glowroot include:
- Real-time monitoring of response time, throughput, error rates etc.
- Transaction tracing showing exact timings across distributed systems
- Dynamic collection of additional detail via Aspects
- Aggregation of metrics across multiple application instances
- Overhead as little as 1% so can be used in production
- Simple browser-based user interface for alerts, reports and analysis
- Built-in JVM diagnostics capability
- Open source with an Apache license
Glowroot works by using bytecode instrumentation to add monitoring probes to the application code without changing any application logic. This allows it to provide very detailed monitoring data with minimal overhead. The centralized collector aggregates and analyzes data across all application instances.
With its ease of use, low overhead, and rich set of features for identifying performance issues - Glowroot forms an invaluable APM tool for monitoring Java applications in dev, test and production environments.
