5.2.9 JVM Heap Interval File (WEBHPI)


The JVM Heap Interval (WEBHPI) file is derived from the
SMF type 120, subtype 3 records.  The heap interval data is
logged with subtype 3, which is written each time an activity
occurs in the J2EE (Java II Enterprise Edition) servant
(server region) at the site-specified interval.  It contains
information about the specific heap and its size.

The following sections describe the file's organization, list
data elements maintained, and provide usage hints and
examples.
