How do I find performance bottlenecks?
Bottlenecked areas, where a single or limited number of items restrict the
performance of a resource, can be identified using the administrator dashboard,
alerts, or the Capacity Planner.
The administrator dashboard hosts widgets that monitor various performance
contention metrics such as CPU, memory, disk, I/O, and storage metrics. By using
the dashboard, you can quickly view which areas per resource may need to be
addressed. You can create alerts for other areas that you want to monitor that are
not included in the default alerts. By using the Capacity Planner you can
proactively identify what will become a bottleneck in the future. For more
information, see Capacity planning.
How can I diagnose historic performance issues?
Virtualization Manager collects data and stores it to compile historical information
about the resources, which is most effective when enough time has elapsed to
create a large base of comparison.
For example, I/O latency data is not available until data has been collected for
some time, and the accuracy of the information increases as more data is
gathered. You can use the dashboard to look at current trend information, while
the historical performance analyzer charts allow more in-depth views to issues
and trends in your resources.
For more information, see Historical performance analyzer charts.
How do I create a virtualization capacity plan?
You can use the Capacity Planner to view potential bottlenecks, plan additions to
your current infrastructure, or determine when you need to expand your capacity.
Information is drawn from you current environment and data sources to compile
your current capacity and to predict the potential capacity.
Additionally, you can use the dashboards and alerts to monitor your current
capacity for spikes that indicate changing needs.
For more information, see Capacity planning.
