Resource view Enables you to monitor the usage of CPU, disk, network, and memory resources in real time and to identify which processes use which resources.
Reliability Monitor report Tracks changes to the system (including application installation, operating system updates, and driver updates) against an overall stability index that recognizes operating system crashes, application crashes, driver failures, and hardware failures as reductions in reliability.
Data Collector Set Groups data collectors into reusable elements for use with different performance monitoring scenarios.
Unified property configuration Enables you to configure all data collection, including scheduling.
Performance Logs and Alerts features Include scheduling of log collection, with improvements to security and reusability of configurations.
