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).
