YourKit Java Profiler
YourKit Java Profiler examines Java applications and servers, whether they run on a local machine or remotely, during development, testing, or production.
What YourKit Java Profiler is
YourKit Java Profiler examines Java applications and servers, whether they run on a local machine or remotely, during development, testing, or production. CPU data can be viewed as call trees or hotspot lists, and its what-if feature estimates the effect of possible optimizations without another profiling run. Memory views map the object heap and graph, including the amount of 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. It also surfaces slow SQL queries and HTTP requests, with support for databases including MongoDB, Cassandra, and HBase. Plugins for Eclipse, IntelliJ IDEA, and NetBeans link results to source code. Remote use needs SSH access; UI-agent communication uses SSL-encrypted TCP/IP. The desktop profiler has Linux, macOS, and Windows downloads, plus APIs and command-line tools for automation. A free plan and a paid model are listed; the pricing note gives From $99/user/yr · 15-day trial.
Good
- CPU call trees, hotspots, and what-if analysis
- Memory views show retained memory per object
- More than 40 inspections flag performance issues
- IDE plugins link results to source code
- Remote profiling uses SSH access
Watch out
- Advanced support is required for several operating systems
- Evaluation license is limited to up to 15 days
Who it suits
It suits Java developers who need to inspect CPU, memory, database, or HTTP performance locally or remotely. Teams using Eclipse, IntelliJ IDEA, or NetBeans can use the IDE plugins to navigate from profiling results to source code.
Verdict
YourKit Java Profiler combines CPU and memory analysis with inspections, database and HTTP monitoring, and remote profiling. Check its support tier if profiling on AIX, FreeBSD, HP-UX, Linux PPC, or Solaris is required.
