 Command Line Analysis

Use the Platform Profiler analysis type to get a holistic view of system behavior. Gain insights into platform-level configuration, utilization, and imbalance issues that relate to compute, memory, storage, IO and interconnects. Use this low-overhead analysis to collect data 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.
