YourKit Java Profiler
YourKit Java Profiler analyzes Java applications and servers locally or remotely in development, testing and production. CPU results can be viewed as call trees or hotspot lists, and a what-if feature estimates optimization gains without another profiling run. Memory views map the heap and object graph, including the memory retained by each object. More than 40 inspections flag issues such as leaked webapps, duplicated objects, unclosed SQL statements, inefficient collections and I/O operations. The profiler also identifies slow SQL queries and HTTP requests and supports databases including MongoDB, Cassandra and HBase. Plugins for Eclipse, IntelliJ IDEA and NetBeans link profiling results to source code. Remote profiling needs SSH access, while UI-to-agent communication uses SSL-encrypted TCP/IP. Downloads are available for Linux, macOS and Windows; APIs, command-line tools and export formats support automation. A free plan and a paid model are listed, and an evaluation license can be requested for up to 15 days. The pricing note gives a starting price of $99/user/yr.
