Counters related to contention such as Compression, Swap, and Latency are no longer available. The Latency counter would be especially useful to track at cluster level if you have a large environment.

The data is not available in real time. This means the data granularity is at 5-minute intervals, not 20 seconds. As the rollup is an average, it means any spike within a 5-minute period may not be visible. In practice however, most performance problems would still likely be detectable with 5-minute data points.

The counters do not take HA into account. For example, the Total counter sums all the host physical memory.
