Platform Profiler Analysis

Use the Platform Profiler analysis type to get a holistic view of system behavior. Get insights into platform configuration, utilization, performance, and imbalance issues related to compute, memory, storage, IO and interconnects. Use this low-overhead analysis type to perform system characterization on a deployed system that runs a full load over an extended period.
Platform profiler analysis is a coarse-grained, system level analysis that can help you triage and characterize your system for a particular workload. It differs from the System Overview Analysis in some important ways.
