•
TimeStampedCounter
Counts from each "raw" data point are summed, producing a long value for the total
count during the summarized interval.
•
TimeStampedGauge
Values from each "raw" data point are averaged, producing a double value for the
gauge reading during the summarized interval.
•
TimeStampedHistogram
Sample counts from the "raw" data points are summed and the minimum and maximum
for the interval are computed by finding the lowest minimum and highest maximum
among the "raw" data points, producing three long values for the total sample count and
minimum and maximum sample values during the summarized interval. The means of the
"raw" data points are averaged and their standard deviations combined, producing two
double values for the mean and standard deviation of the sample values during the
summarized interval.
•
TimeStampedMeter
Sample counts from the "raw" data points are summed and rates from the "raw" data
points are averaged, producing a long value for the total sample count and a double
value for the average rate during the summarized interval.
•
TimeStampedRatioGauge
Ratio values from each "raw" data point are averaged, producing double values for the
numerator and denominator readings during the summarized interval.
•
TimeStampedRollingCounter
Delta values from each "raw" data point are summed, producing a long value for the
total delta during the summarized interval.
•
TimeStampedTimer
Sample counts from the "raw" data points are summed and the minimum and maximum
for the interval are computed by finding the lowest minimum and highest maximum
among the "raw" data points, producing three long values for the total sample count and
minimum and maximum sample values during the summarized interval. The means and
rates of the "raw" data points are averaged and their standard deviations combined,
producing three double values for the mean, average rate, and standard deviation of the
sample values during the summarized interval.
JMX Clients
JConsole or another JMX client may be used to connect to the HP VAN SDN Controller's JMX
server to view selected metric values "live". Access is only permitted for local JMX clients, so any
such clients must be installed on the controller system. No JMX clients are delivered with the
controller or are among the prerequisites for installing it; they must be installed separately. For
example, the openjdk-7-jdk package must be installed on the controller system to use JConsole.
Which TimeStampedMetrics are exposed via JMX is determined at the time of their creation, by a
field in the MetricDescriptor used to create each TimeStampedMetric. Once the controller has been
properly configured to permit local JMX access the user can inspect the exposed
TimeStampedMetrics as they are updated "live" by the components or applications within the
controller or external application components that created them.
