Delta

When data is collected as a cumulative value, delta is used to display the data as the amount by which the data has changed. For example, if the first performance data item collected is 3 and the second performance data item collected is 4, the cumulative value of 7 and a changed amount of 1 are stored. Whether the value in each field is a delta value is indicated in the Delta column of the Field table. Performance data collected by PFM - RM for Virtual Machine varies as shown in the table below.

Note that the delta value can be a negative value since it is a relative value that depends on the last data item.
