This chapter introduced tools and techniques useful for monitoring Microsoft Office Communications Server. These tools—including event logs, performance monitoring, the Archiving Server, the Monitoring Server, the Deployment Validation Tool, and management packs for Microsoft Operations Manager and System Center Operations Manager—enable you to track the health both of your Office Communications Server infrastructure in general and of individual Office Communications Server servers in particular. These tools also enable you to gather data that provides information about how UC is actually used in your organization.
