•Event Action. The action that occurred. For definitions of these actions, see the section called “Audit Log Event Names”.
•Succeeded. This provides that status of the action (that is, whether or not it was successful).

Pool Health
The pool health report displays the percentage of time a resource pool and its hosts spent in four different threshold ranges: Critical, High, Medium, and Low. You can use the Pool Health report to evaluate the effectiveness of your performance thresholds.
A few points about interpreting this report:
•Resource utilization in the Average Medium Threshold (blue) is the optimum resource utilization regardless of the placement strategy you selected. Likewise, the blue section on the pie chart indicates the amount of time that host used resources optimally.
•Resource utilization in the Average Low Threshold Percent (green) is not necessarily positive. Whether Low resource utilization is positive depends on your placement strategy. For example, if your placement strategy is Maximum Density and most of the time your resource usage was green, Workload Balancing might not be fitting the maximum number of virtual machines possible on that host or pool. If this is the case, you should adjust your performance threshold values until the majority of your resource utilization falls into the Average Medium (blue) threshold range.
•Resource utilization in the Average Critical Threshold Percent (red) indicates the amount of time average resource utilization met or exceeded the Critical threshold value.
If you
If you find the majority of your report results are not in the Average Medium Threshold range, you probably need to adjust the Critical threshold for this pool. While Workload Balancing provides default threshold settings, these defaults are not effective in all environments. If you do not have the thresholds adjusted to the correct level for your environment, Workload Balancing's optimization and placement recommendations might not be appropriate. For more information, see the section called “Changing the Critical Thresholds”.
