Abstract
A logging service logs diagnostic messages from applications executing in a mainframe computing environment to a centralized log. A mainframe computing environment has a plurality of mainframes coupled to a coupling facility. The coupling facility has a data storage area called a “logstream.” Each mainframe has one or more subsystems executing applications. Each application preferably contains an API block, which is populated by the application and passed to a logging service API when the application desires to store a diagnostic message in the logstream. The logging service API writes the diagnostic messages to the logstream. In one subsystem, the logging service API contacts an alert facility in response to certain diagnostic messages received from applications. The logging service API in this subsystem also uses a message queue to pass the diagnostic messages to a subsystem able to write to the logstream.
