Class StatisticsCollectorForWindows

java.lang.Object
  com.bigdata.counters.AbstractStatisticsCollector
      com.bigdata.counters.win.StatisticsCollectorForWindows

All Implemented Interfaces:

IStatisticsCollector

public class StatisticsCollectorForWindows
extends AbstractStatisticsCollector

Collects per-host performance counters on a Windows platform.

Note: The concept of a PID exists for Windows, but it is not relevant to collection of performance counters since Windows does not appear to support collection by PID, only by the process name. Since we run multiple services per host, collection by process name is not sufficient to facilitate decision making by the load balancer. Instead, the load balancer relies on service specific performance counters, including the average queue length and response time.

Method Detail

start

public void start()

Description copied from class: AbstractStatisticsCollector

Start collecting host performance data -- must be extended by the concrete subclass.

Specified by:

start in interface IStatisticsCollector

Overrides:

start in class AbstractStatisticsCollector

stop

public void stop()

Description copied from class: AbstractStatisticsCollector

Stop collecting host performance data -- must be extended by the concrete subclass.

Specified by:

stop in interface IStatisticsCollector

Overrides:

stop in class AbstractStatisticsCollector

getCounters

public CounterSet getCounters()

Description copied from class: AbstractStatisticsCollector

Return the counter hierarchy. The returned hierarchy only includes those counters whose values are available from the JVM. This collection is normally augmented with platform specific performance counters collected using an AbstractProcessCollector.

Note: Subclasses MUST extend this method to initialize their own counters.

Specified by:

getCounters in interface IStatisticsCollector

Overrides:

getCounters in class AbstractStatisticsCollector
