|
JVM Browser
|
| |
Test connection |
In the New Connection Wizard a connection can be tested
- to ensure that host name, port, password etc. are
correct - before it is added to JVM Browser Tree.
|
|
| |
User configurable application names |
The user can now, by using a set of naming rules, give
discovered Java-applications human readable names in the
JVM Browser.
|
|
General
|
| |
Accessibility support |
The Management Console, the JRockit Runtime Analyzer and
the JVM Browser now have better support for keyboard navigation.
Custom widgets in Mission Control, like graphs and pie
charts, now provide information for screen readers.
Graphs and dials in the Management Console Overview can also be
rendered as tables by changing accessibility options in
Preference Dialog.
|
|
| |
Links to Mission Control forum and home page |
To help the user to find further assistance and
information about Mission Control, the help menu now
contains links to the Mission Control Forum and Home
Page.
|
|
| |
Better support for Copy and Paste |
Copy and Paste now work for all tables and trees in the
Management Console, the JRockit Runtime Analyzer and for
the Properties View. Settings for turning column headers
on/off and for indenting columns when copying trees have
been added.
|
|
JRockit Runtime Analyzer (JRA)
|
| |
New recording templates |
There are four new templates in the JRA-recording
wizard. The "Full Recording"-template is the default one
and it will try to gather as much information as
possible without worrying too much about the overhead.
The "Minimal Overhead Recording"-template will try to
minimize overhead even if it means that some data will
not be recorded.
The "Real Time Recording"-template is the one to slect
when you are use JRockit Real Time, as it will omit some
data that provoke garbage collections when collected.
For older versions of JRockit, which lacks the support
for recording latency related information or that uses a
JDK 1.4, which does not support file transfers back to
Mission Control, there is a template called "Classic
Recording".
|
|
| |
Toolbar navigation |
The tabs in the Runtime Analyzer have been splitted up
into six groups: General, Memory, Code, Threads/Locks,
Latency and Other and a toolbar has been added so the
user can navigate between the different groups.
|
|
| |
General Tab |
There is a new overview tab that presents an aggregated
view of selected data from the whole recording graphically.
|
|
| |
Code Overview Tab |
There is a new overview tab for code related information
that shows in what packages and classes the application
spent the most time executing.
|
|
| |
System Tab |
There is a new System Tab that shows JVM and OS-related
information.
|
|
| |
Recording Tab |
There is a new Recording Tab that shows the start time
of the recording and the recording parameters used.
|
|
| |
GC Statistics Tab |
The GC General tab has been renamed to GC Statistics and
it now contains more detailed information about GC pauses
and GCs.
|
|
| |
Allocation Tab |
There is a new tab that shows thread local area (TLA)
information and the ratio between the number of bytes
allocated by small and large objects in the application.
It is now also possible to see how much memory each
thread has allocated during the recording.
|
|
| |
Threads/Locks Overview Tab |
There is a new overview tab showing information about
threads, locks and CPU usage.
|
|
| |
Thread Tab |
There is a new tab that shows the threads that were
running during the recording.
|
|
| |
Latency Overview Tab |
There is a new overview tab displaying latencies
categorized by type. The tab also shows which Java locks
the application were blocked on the most.
|
|
| |
Latency Thread Tab |
There is a new tab that shows the total and average
latency per thread.
|
|
| |
Latency Histogram Tab |
The Event Value Histogram folder in the Latency Log Tab
has moved to separate tab called the Histogram Tab and a
details part, that shows the traces for all events that
have a certain event value, has been added. This can be
useful when trying to find out where in the application
there has been contention on a lock.
|
|
| |
Occupied Heap |
An Occupied Heap data series, which shows the amount of memory after a
garbage collection, has been added to GC Event Tab.
|
|
| |
Improved threads tooltips |
The tooltip for a thread in the Latency Graph now shows
start and end time for the thread, the thread id and the
total allocation rate.
|
|
| |
Improved Tooltips for pie charts |

information about each slice.
|

| |
Configurable tab navigator |
The position of tab navigator (category toolbar) can now be configured by the
user.
|
|
Eclipse Integration
|
| |
Tab extension point |
There are now extension points that allow third parties
to extends the Management Console with tabs, trigger
rules and triggers actions.
|
|
| |
PDE wizards |
Eclipse Wizards for creating classes, that can use the
new extension points exposed by Mission Control, have
been added.
|
|
API
|
| |
New public API:s |
The RJMX-API, which is an extension of JMX that Mission
Control uses to subscribe to JMX-data and to establish
connections to local/remote servers, is now open for
public use. The API also includes classes that allow
communication with JRockit JDK 1.4, which relies on a
JRockit specific protocol instead of JMX. Accompanying
the RJMX-API is two Eclipse-plug-ins which exposes
API-functionality that can be used to extend Mission
Control and create dials, tables and charts similar to
the ones found in Mission Control today.
