Computer-implemented methods and apparatus are provided for collecting
information gathered by an instrumentation mechanism for transport to an
information collection facility. In one embodiment, the information that
is collected is defined by a configuration file. An application may
examine the configuration file, execute one or more queries specified by
the configuration file, and write the data which is collected to one or
more data structures employed by a transport mechanism in transferring
information to the information collection facility. The process of
collecting the information may occur periodically, such as nightly. The
configuration file may be periodically updated to reflect new information
that is to be collected.
