The Health Center provides vital status information about the resources that your instance uses. One of the most important resource groups being monitored is memory. If health indicators for the memory resource group suggest that there is some problem that needs to be addressed, you can use the new Memory Visualizer tool to analyze the problem further (see Figure 12.12). The Memory Visualizer shows details of memory allocation and utilization for a particular instance and all of its databases. It displays information about sort heaps, buffer pools, and caches. Such information, conveniently displayed, makes it easy for you to troubleshoot memory resource problems.
