An execution environment accommodating object-based software transparently
monitors interactions with software objects to generate operational
management information for managing programs executing at plural
computers. Notifications are directed to a software manager in the form of
events, which can additionally be provided to applications or user
programs. The software manager can group the events into sets and derive
various operational management metrics from them to provide an overall
picture of a program's performance, including availability. A hierarchical
arrangement feature facilitates gathering information for programs
scattered over plural computers. An alert feature provides warnings if
metrics fall outside a specified threshold. In addition, the alert feature
can automatically subscribe to additional sets of events to dynamically
select the information collected by the software manager. Since the
operational management information is collected transparently by logic
outside the objects, manual instrumentation of the program is unnecessary,
and software management technology is made available to organizations
without software management expertise.
