A distributed logging system for maintaining and retrieving diagnostic logging information in an efficient manner. A local cache of logging information is maintained at an analysis computer and the local cache is first examined to determine if diagnostic information exists in the cache or if it must be retrieved from a remote server. If the requested diagnostic information is available in the local cache, the local cache is accessed to retrieve the information. If any portion of the requested diagnostic information is not available in the local cache, the information is located and read from the appropriate log file(s) on the remote server, and then stored in the local cache so that subsequent requests for that diagnostic information will not necessitate accessing the remote computer. Native I/O functions are used to allow access to the diagnostic information regardless of the status of the distributed system.
