We used Dell EMC Live Optics for collecting data and validating the use case tests that are described in this document. Live Optics is a free, agentless software used for collecting data from PowerEdge servers. In just minutes, any user can set up Live Optics to collect a wealth of information for configuration and resource utilization analysis. The intuitive Live Optics dashboard enables DBAs to monitor and collect data across the server and VMware virtualization layers.
The following figure shows a Live Optics dashboard. The left side shows performance at the project, hypervisor, virtual server, and shared disk levels. The right side shows the collected data and graphs that can assist with quick visual analysis.
