Method Details

buildProcessMapFromRegistry

public static Map<Integer,ProcessPerformanceData.PerfCounterBlock> buildProcessMapFromRegistry(Collection<Integer> pids)

Query the registry for process 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 Process ID as the key and a ProcessPerformanceData.PerfCounterBlock object populated with performance counter information if successful, or null otherwise.

buildProcessMapFromPerfCounters

public static Map<Integer,ProcessPerformanceData.PerfCounterBlock> buildProcessMapFromPerfCounters(Collection<Integer> pids)

Query PerfMon for process 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 Process ID as the key and a ProcessPerformanceData.PerfCounterBlock object populated with performance counter information.

buildProcessMapFromPerfCounters

public static Map<Integer,ProcessPerformanceData.PerfCounterBlock> buildProcessMapFromPerfCounters(Collection<Integer> pids,
 String procName)

Query PerfMon for process performance counters

Parameters:

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

procName - Filter by this process name.

Returns:

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