The
Real-Time
View of resource utilization is provided below the
Utilization
History. The display is a heat map for each of the monitored
resources, CPU, memory, and network
I/O. Each column in the heat map
represents a machine in the cluster. To view the real-time resource
utilization for a resource type, position your pointer over one of
the cells in the heat map.
For the section that
shows CPU utilization, the tooltip shows the host name, CPU number,
and the CPU utilization as a percentage. For the section that shows
memory utilization, the tooltip shows the host name and memory utilization
as a percentage. Both of these resources have a range of zero to 100.
The color changes to represent the work load.
The bottom section shows
two rows to represent network
I/O. The top row shows the transfer
rate for output and the bottom row shows the transfer rate for input.
The tooltip shows the host name, the direction, and the rate. The
color for the icons depends on the transfer rate between 0 and 25
megabytes per second. If the transfer rate exceeds 25 MB per second,
then the icon color changes to purple.
