Table 1‑2. Data Counter Attributes
Attribute Description
Unit of Measurement Standard in which the statistic quantity is measured.
n
Kilobytes (KB) – 1024 bytes
n
Kilobytes per second (KBps) – 1024 bytes per second
n
Kilobits (kb) – 1000 bits
n
Kilobits per second (kbps) – 1000 bits per second
n
Megabytes (MB)
n
Megabytes per second (MBps)
n
Megabits (Mb), megabits per second (Mbps)
n
Megahertz (MHz)
n
Microseconds (µs)
n
Milliseconds (ms)
n
Number (#)
n
Percent (%)
n
Seconds (s)
Description Text description of the data counter.
Statistics Type Measurement used during the statistics interval. Related to the unit of measurement.
n
Rate – Value over the current statistics interval
n
Delta – Change from previous statistics interval.
n
Absolute – Absolute value (independent of the statistics interval).
Rollup Type Calculation method used during the statistics interval to roll up data. Determines the type of statistical
values that are returned for the counter.
n
Average – Data collected during the interval is aggregated and averaged.
n
Minimum – The minimum value is rolled up.
n
Maximum – The maximum value is rolled up.
The Minimum and Maximum values are collected and displayed only in statistics level 4. Minimum and
maximum rollup types are used to capture peaks in data during the interval. For real-time data, the
value is the current minimum or current maximum. For historical data, the value is the average
minimum or average maximum.
For example, the following information for the CPU usage chart shows that the average is collected at
statistics level 1. The minimum and maximum values are collected at statistics level 4.
n
Counter: usage
n
Unit: Percentage (%)
n
Rollup Type: Average (Minimum/Maximum)
n
Collection Level: 1 (4)
n
Summation – Data collected is summed. The measurement displayed in the chart represents the sum
of data collected during the interval.
n
Latest – Data collected during the interval is a set value. The value displayed in the performance charts
represents the current value.
Collection level Number of data counters used to collect statistics. Collection levels range from 1 to 4, with 4 having the
most counters.
Note Be careful when you set a higher collection level, as the process requires significant increase of
resource usage. For more information, see Data Collection Levels.
