Method Details

buildThreadMapFromRegistry

public static Map<Integer,ThreadPerformanceData.PerfCounterBlock> buildThreadMapFromRegistry(Collection<Integer> pids)

Query the registry for thread performance counters

Parameters:

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

Returns:

A map with Thread ID as the key and a ThreadPerformanceData.PerfCounterBlock object populated with performance counter information if successful, or null otherwise.

buildThreadMapFromPerfCounters

public static Map<Integer,ThreadPerformanceData.PerfCounterBlock> buildThreadMapFromPerfCounters(Collection<Integer> pids)

Query PerfMon for thread performance counters

Parameters:

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

Returns:

A map with Thread ID as the key and a ThreadPerformanceData.PerfCounterBlock object populated with performance counter information.

buildThreadMapFromPerfCounters

public static Map<Integer,ThreadPerformanceData.PerfCounterBlock> buildThreadMapFromPerfCounters(Collection<Integer> pids,
 String procName,
 int threadNum)

Query PerfMon for thread performance counters

Parameters:

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

procName - Limit the matches to processes matching the given name.

threadNum - Limit the matches to threads matching the given thread. Use -1 to match all threads.

Returns:

A map with Thread ID as the key and a ThreadPerformanceData.PerfCounterBlock object populated with performance counter information.
