Defect Tracking NumberNew Behavior in 3.0.01.00Behavior in 3.0.x or Older Versions
QXCR1000768627When viewing the Threads Histogram after switching to Thread Group Scope and back to Process Scope, the entries in the Sort menu correctly affect the presentation of data in the Threads Histogram.When viewing the Threads Histogram after switching to Thread Group Scope and back to Process Scope, selecting entries in the Sort menu has no effect on the display of data in the Threads Histogram.
QXCR1000748051When HPjmeter is used to view Xeprof data, the state of the metric menu items is updated whenever scope is changed; for example, from one thread to another thread or from one thread group to another thread group, such that the menu items are always correctly enabled for the type and scope of data available for a thread. Metric menu items are updated only when the scope type is changed; for example, from process scope to thread scope. Because some eprof data files can have different types of data available for some threads, it is possible to have some (or all) of the menu items incorrectly disabled for some or all threads.
QXCR1000716715When HPjmeter is used to view Xeprof data , HPjmeter accurately displays the data appropriate to any scope changes made in the metric visualizers.HPjmeter does not correctly display reported information when a user changes from Process scope to Thread or Thread Group scope and then back to Process scope. After an initial scope change occurs, any subsequent scope change back to Process scope does not display data appropriate to the scope.
JAGag10494The HPjmeter agent has been modified to cleanly disable the collection of metric data during a rapid shutdown.The HPjmeter agent does not cleanly disable data collection during a rapid shutdown in response to a JVM issue, such as an out-of-memory condition. This can result in a runtime failure in the agent code.
JAGag25728HPjmeter includes a working help index with its help reference.Entering a keyword into the search field of the HPjmeter help reference hangs the help search function. When this happens, the user can click the contents or index tab to find help topics, but the search on keyword function does not work.
JAGag26903HPjmeter presents English help information when localized help is not available for non-English locales.HPjmeter fails to present English help information when localized help is not available for non-English locales.
JAGag33573HPjmeter correctly interprets transfers of instrumented versus non-instrumented objects (arrays) between Java instances.A user who transfers an instrumented object (an array of a particular collection class; e.g,. HashMap) to another Java instance that does not know about the instrumentation, will see an exception error message.
JAGag35946Text fields in the standard dialog boxes are now localized and characters display correctly.Text fields in some standard dialog boxes (like file selection) are not localized and display English text. Some fields that are localized display a square box in place of some non-English characters. This is most noticeable in Asian locales.
JAGag36508The algorithm used to draw the scrolling, time-based visualizers has been updated to improve performance when viewing data that has been collected from a long-running Java application.User can experience slow display window response or apparent hanging of the console when viewing data collected from a long-running Java application.
JAGag37610HPjmeter agent checks to see if XX+UseConcMarkSweepGC is in use. If it is, HPjmeter does not enable data collection for the Live Objects in Heap functionality. This allows other HPjmeter data collection to work normally. (The Live Objects in Heap metric is available with Java 5.0 or later.)With Java 5.0, HPjmeter agent does not start when XX+UseConcMarkSweepGC is enabled.
JAGag37928The console first attempts to use a port between 9505 and 9515 when arranging a port for its server socket. If it is unable to successfully use a port from this range, it will assign an ephemeral port number. When a user opens a session, the console creates a new server socket using an unknown port number; expecting the node agent to communicate using this new port. Since the port number is not known in advance, it is difficult to arrange for the firewall to pass this port through.
JAGag37933HPjmeter console cleanly closes the socket used to communicate with the node agent. The HPjmeter console does not always cleanly close the socket used to communicate with the node agent. This means that, over time, multiple sockets may be left in waiting states, and further requests to obtain a socket can fail.
JAGag45409HPjmeter is an order of magnitude faster at plotting points from very large verbosegc files when switching among metric tabs.When analyzing a very large verbosegc file, it can take 15 to 30 seconds initially to see a new graph upon switching metric tabs in HPjmeter.
JAGag46593HPjmeter supports saving and printing garbage collection data (in .png format) that is displayed graphically in HPjmeter.HPjmeter does not allow printing of garbage collection data in graphical displays.
