All devices Agent/WMI/SNMP across all pollers stopped populating Peak CPU load on graphs. I have a ticket open but was hoping someone might have seen this. The Peak CPU and AVG CPU load are the same numbers.
For data inside the detailed retention period the min/max/avg values are all the same. They only start to diverge once the data gets rolled up into the hourly and daily intervals (after 7 days by default) So in your case the peak isn't "gone" so much as it is the same as the avg and is hiding behind it.
