Create an alarm. Creating host and virtual machine alarms is a proactive way to be alerted to abnormal behavior for all four resource groups or state changes. Alarms can be applied to a single host or virtual machine or a group of either object in the VirtualCenter hierarchy.

Master It Creating host and virtual machine alarms.

Work with graphs Creating and working with Performance graphs is the best way to monitor what is currently happening in your virtual infrastructure. Maybe more important, though, is a graph's ability to analyze trends in the performance of your hosts and virtual machines. Graphs can be saved and archived or printed for justifying purchase decisions or showing before-and-after comparisons after adjustments have been made to either hosts or virtual machines.

Master It Creating graphs for hosts and virtual machines.

Master It Using esxtop to monitor resources on a single ESX host.

Customizing Host and Virtual Machine Graphs for CPU, Memory, Disk, and Network Adapters.

Master It Use the graphs to monitor CPU usage regularly for hosts and the virtual machines.

Master It Create graphs showing host memory usage using the various objects, counters, and chart types.

Master It Create graphs showing virtual machine memory usage using the various objects, counters, and chart types.

Master It Create graphs showing host and virtual machine network usage using the various objects, counters, and chart types.

Master It Create graphs showing host and virtual machine usage using the various objects, counters, and chart types.

Save a graph Graphs can be saved as evidence, I mean justification, as to why new hardware is required.

Master It You need to provide a graph to upper management in support of your proposal for two new servers to be configured as ESX Server hosts.
