摘要： An administration server in a database management system retrieves log files in a plurality of formats from a plurality of clients through helper programs running on the clients. The plurality of clients can include Web servers, application servers, and database servers. The log files can be generated by software modules on the clients. An administration engine converts log entries in the log files into a unified format for display. The converted log entries can be stored in a log database. Upon a user request, the administration server presents the log entries to the user in a log viewer. The log viewer can display log entries originated from heterogeneous software modules in a unified view.
