The following features make this a great tool to checkout:
Performance monitoring: Comprehensive data on resource consumption and workload, from vCenter, ESX/ESXi host, and complete down to the individual VM. Real time data consolidated in one place.
Hardware monitoring: Provides a complete picture of your datacenter, through CIM/SMASH API – track everything from temperature and fan speed, to ventilation, power and more – eliminating the need for service console based hardware monitoring agents.
Correlation of event and performance data: See all of your datacenter activities on a single page, in real time. No need to switch between different virtual machines, hosts or vCenters – all information in under one easy to modify view.
User interface optimized for monitoring: The interface was designed with monitoring, not control in mind.
