 |absolute|Represents an actual value, level, or state of the counter. For example, the “uptime” counter (system group) represents the actual number of seconds since startup. The “capacity” counter represents the actual configured size of the specified datastore. In other words, number of samples, samplingPeriod, and intervals have no bearing on an “absolute” counter“s value.|
