Memory utilization value of server in UIM is not matching with value showing in server. We are monitoring these servers using vmware probe.


UIM 8.x, 9.x


VM Memory Usage QOS is calculated by averaging the values of counter 'usage' in the past 10 mins(resource data collection interval). In Vcenter, a new counter value is available every 20 seconds, thus we get 30 values for the counter in 10 mins, its average value becomes the QOS value at that point of time. In Vsphere client, we see the performance graph for the above counter based on latest values. The average value of the counter is also available but the duration for which the average is calculated will not match the duration for which the probe calculates the average - thus the values may not exactly match.
