A management pack is a definition file (either with an .xml or .mp extension) that contains predefined monitoring settings that enable an agent to monitor a specific service or application in Operations Manager 2007 or Essentials 2007. These predefined settings include discovery information that allows Operations Manager and Essentials to automatically detect and begin monitoring services and applications, and a knowledge base that contains error and troubleshooting information, alerts, and reports to help you correct the problems detected in your environment.
