Connectivity and I/O Performance Monitoring

Foglight for Storage Management provides comprehensive topology views which detail all I/O paths and components on each I/O path from VMs down to their assigned physical storage devices. These views assist in determining where actual performance or connectivity problems are occurring during I/O requests, something which is not possible using traditional virtual infrastructure management tools. For more information, see Assessing Connectivity and I/O Performance.
