1.7 HPjmeter
With the release of HPjmeter 3.0, all previous versions of HPjmeter (1.x, 2.x) are no longer
available for download and are no longer supported by HP.
If you have an old version of HPjmeter, please download HPjmeter 3.0 from:

HPjmeter can be used to identify and diagnose performance problems in Java applications
running on HP-UX. It can be used for both static and dynamic data analysis. For example, for
static data analysis it can be used to analyze profiling data generated by the following
command-line options: -Xrunhprof:heap=dump, -Xeprof, -Xverbosegc, -Xloggc, and
–XX:+HeapDump. Additionally, when using JDK 1.5.04 or later releases, HPjmeter can capture
profiling data with zero preparation (that is, without pre-planning). HPjmeter can also be used
for dynamic data analysis by monitoring live Java applications.
The following table lists the features of HPjmeter 3.0. The first two rows are static features and
the remaining four rows are dynamic features.
