YourKit Early Access Program (EAP) is the easiest way to get in touch with the latest technologies from YourKit.
You can have early access to new products and internal builds.
NOTE: THIS IS PREVIEW SOFTWARE AIMED AT PROVIDING YOU WITH AN OPPORTUNITY
TO TEST THE NEWEST FEATURES SCHEDULED FOR THE NEXT MAJOR RELEASE.
YOURKIT DOES NOT GUARANTEE THAT THIS SOFTWARE WILL RUN TROUBLE-FREE.
USING THIS SOFTWARE IS AT YOUR OWN DISCRETION AND DOES NOT ENTITLE YOU TO ANY
Your comments, suggestions and bug reports are welcome. In the forum you
can discuss product features with YourKit developers and post bug reports.
Improved auto-scrolling to selected thread in "Threads" view.
Refinement of "Welcome" screen layout.
Bug fixes and performance improvements.
Changes in build 51
Better filtering of development tools in "Monitor Application" section on "Welcome" screen
Changes in build 50
[new] IDE integration: IntelliJ IDEA 2018 supported
[new] Dedicated docker zip now includes the agent for ppc64le too
[new] Horizontal scrolling with mouse wheel and two fingers gesture in telemetry graphs
[regression] Tracing was broken in attach mode
Changes in build 48
Java 10 supported
Welcome screen: all possible actions enabling different profiling scenarios
are available in one place under the section "Get Started with Profiler"
Welcome screen: local and remote profiling applications are shown in real time in
the section "Monitor Applications"
added ability to attach the profiler agent to a remote Java process started without the profiler agent
directly from the profiler UI
multihop SSH tunnels:
the remote connection dialog allows to set up an SSH tunnel through any number of intermediate machines
Simplified and improved profiling in Docker containers:
dedicated compact download bundle containing only files needed in docker reduces container size and build time
agent dependencies on glibc relaxed, which is important for Apine Linux based containers
new dedicated Help topic provides step by step instructions on how to profile in a container
New feature: Threads view now shows per-thread CPU usage graphs
Threads view: to improve visibility, thread header elements are vertically aligned
Threads view: ability to see the stack trace for particular event
Threads view: ability to change scale
Telemetry: new graph scaling option "Fit to Width"
Searchable stacks in telemetry
CPU HPROF dumps supported.
The profiler is now able to open HPROF dumps with CPU samples which are produced
by running java -agentlib:hprof=cpu=samples,format=b <...> or
java -Xrunhprof:cpu=samples,format=b <...>
UI: stacked hints and messages
UI: reworked IDE integration
UI: reworked local server integration
Improved stack trace presentation in different views: quick info, deadlocks, etc.
If the user allows, the profiler now may collect anonymous UI usage statistics to
help YourKit improve user experience in future versions
Startup option port was extended to allow a specification of a port range too.
The syntax is port=<min_port>-<max_port>.
Also, the remote connection dialog now allows to specify the remote agent port range.
Agent: improved control of the profiler agent connectivity options.
The startup option listen has been extended.
Most security, the default option: listen=localhost binds the profiler agent socket to localhost only.
This will disable a direct remote connection to the agent via <host>:<port>.
Connection to the profiler agent will be possible via port forwarding e.g. an SSH tunnel.
listen=all opens the profiler agent socket on all network interfaces.
A remote connection to the agent will be possible directly via <host>:<port>.
Note that access to the port can be additionally restricted with a firewall.
listen=<IP or host>[:<port>]
binds the profiler agent socket to particular network interface
Please note that listen=localhost is now the default (the old default was equal to listen=all),
and option onlylocal is deprecated.
macOS: the profiler is now distributed as .dmg bundle
macOS: JetBrains Open JDK for is bundled to improve UI quality, e.g. font rendering
macOS: .snapshot files associated with the profiler application
macOS: prevent the automatic switching to the discrete GPU if the machine has multiple GPUs
macOS: on-screen menu bar for Dark theme too
Improved Linux desktop support: *.desktop file is provided
Linux x64: JetBrains Open JDK for is bundled to improve UI quality, e.g. font rendering
HP-UX: agent detection improved
Profiler UI now may run on Java 9 too, although we still recommend to run it on Java 8
UI: a hint panel for a slave view can be hidden
Attach: gracefully handle inability to attach to IBM Java.
The profiler now shows appropriate error messsage to the user on attempt
to attach to an IBM Java process started without the agent.
This operation is still impossible due to lack of capabilities in IBM JVM,
and IBM Java can be profiled only by starting with the agent.
