About er_print

The er_print utility prints a text version of the various data views supported by Performance Analyzer. The information is written to standard output unless you redirect it to a file. You must give the er_print utility the name of one or more experiments or experiment groups generated by the Collector as arguments.

The er_print utility only works on experiments that were recorded with Oracle Solaris Studio 12.3, and this release, Oracle Solaris Studio 12.4. An error is reported if you use an experiment recorded with any other version. If you have older experiments, you must use the version of er_print from the release with which the experiment was recorded.

You can use the er_print utility to display the performance metrics for functions, for callers and callees; the source code listing and disassembly listing; sampling information; dataspace data; thread analysis data, and execution statistics.

When invoked on more than one experiment or experiment groups, er_print aggregates the experiment data by default can also be used to compare the experiments. See compare { on | off | delta | ratio } for more information.

For a description of the data collected by the Collector, see Chapter 2, Performance Data.
