Class ThreadPerformanceData

java.lang.Object

oshi.driver.common.windows.registry.ThreadPerformanceData

@ThreadSafe
public final class ThreadPerformanceData
extends Object

Common logic for building thread performance data maps from registry or performance counter results. Callers (JNA/FFM variants) supply the platform-specific pre-fetched registry or performance-counter data.

Method Details

buildThreadMapFromRegistry

public static Map<Integer, ThreadPerfCounterBlock> buildThreadMapFromRegistry(Collection<Integer> pids,
 Triplet<List<Map<ThreadInformation.ThreadPerformanceProperty, Object>>, Long, Long> threadData)

Builds a thread map from registry performance data that has already been read.

Parameters:

pids - An optional collection of process IDs to filter the list to. May be null for no filtering.

threadData - The raw registry data triplet (instance maps, perfTime100nSec, now in ms)

Returns:

A map with Thread ID as the key and a ThreadPerfCounterBlock object populated with performance counter information, or null if threadData is null.

buildThreadMapFromPerfCounters

public static Map<Integer, ThreadPerfCounterBlock> buildThreadMapFromPerfCounters(Collection<Integer> pids,
 Pair<List<String>, Map<ThreadInformation.ThreadPerformanceProperty, List<Long>>> instanceValues)

Builds a thread map from performance counter query results.

Parameters:

pids - An optional collection of process IDs to filter the list to. May be null for no filtering.

instanceValues - The query results as a pair of (instances, valueMap)

Returns:

A map with Thread ID as the key and a ThreadPerfCounterBlock object populated with performance counter information, or null if instanceValues is null.
