An Example Comparison Of Match Behavior In Ad And Gwlm For Same Executable Path And - HP 5992-3838 User Manual

Constructing Regular Expressions:
HP Application Discovery recognizes regular expressions constructed using Perl 5 or POSIX
syntax and semantics. To learn more, consult PCRE - Perl Compatible Regular Expressions at
http://www.pcre.org/.
NOTE:
HP Application Discovery (AD) interprets executable path strings differently than
HP Global Workload Manager (gWLM).
HP Application Discovery looks at a process from the perspective of how it is named when it is
running. Therefore, to successfully construct an application that HP Application Discovery
recognizes, you must provide attributes (data strings) that describe the running process.
Also, when defining an application, keep in mind that HP Application Discovery looks across
your entire network for likely matches, and not just on one particular managed node.
It might help to think of the difference between AD and gWLM this way:
• In AD, an executable and arg[0] are compared directly to one another to make a match.
• In gWLM, the inode of an executable and the inode of arg[0] are compared to one another
to make a match.
The following examples demonstrate the different results that you can expect when using the
same executable and arguments in HP Application Discovery as compared to HP Global Workload
Manager (gWLM).
