Perfino

Perfino is a software profiling and performance-monitoring tool designed to help developers analyze the runtime behavior of applications, with a primary focus on Java and other JVM-based environments. It collects detailed metrics and traces from running processes, enabling engineers to identify CPU bottlenecks, memory usage issues, and concurrency problems.

Perfino typically operates as an agent attached to the target process or as an external collector. It supports instrumentation-based and sampling profiling methods, recording CPU time at method or call-site granularity, tracking object allocations and garbage-collection activity, and monitoring thread states and I/O wait times. The data are presented through visualizations such as flame graphs, call graphs, and real-time dashboards, with support for aggregating results across services, instances, or containers to enable distributed analysis.

Usage commonly spans development, testing, and production environments. Perfino aims to balance visibility with overhead by enabling adjustable sampling rates, selective instrumentation, and asynchronous data collection. It often provides integration points for IDEs, build systems, and monitoring stacks, facilitating hot-spot analysis during development cycles and post-mortem investigations after incidents.
