Classe WMI MSiSCSI_InitiatorInstanceStatistics

  • Articolo

La classe WMI MSiSCSI_InitiatorInstanceStatistics espone le statistiche dell'iniziatore.

Poiché questa classe è associata a una particolare istanza di un driver miniport di archiviazione, il driver miniport deve registrare la classe usando il nome dell'oggetto dispositivo fisico specifico (PDO) gestito dal driver miniport.

La classe MSiSCSI_InitiatorInstanceStatistics è definita in Iscsiprf.mof.

class MSiSCSI_InitiatorInstanceStatistics : Win32_PerfRawData {
  [read,key] String InstanceName;
  [read] boolean Active;
  [WmiDataId(1),
    DisplayName("Adapter Id") : amended, DisplayInHex,
    description("Id that is globally unique to each instance 
    of each adapter. Using the address of the Adapter 
    Extension is a good idea.") : amended]
    uint64  UniqueAdapterId;
  [WmiDataId(2), DisplayName("Session Digest Errors"): 
    amended, PerfDefault, CounterType(0x00010000),
    // PERF_COUNTER_RAWCOUNT
    DefaultScale(0), PerfDetail(100), read,
    Description("Count of Session digest errors"): amended]
    uint32  SessionDigestErrorCount;
  [WmiDataId(3), DisplayName("Session Cxn Timeout Errors"): 
    amended, PerfDefault, CounterType(0x00010000),
    // PERF_COUNTER_RAWCOUNT
    DefaultScale(0), PerfDetail(100), read,
    Description("Count of Session connection timeout
    error"): amended] 
    uint32  SessionConnectionTimeoutErrorCount;
  [WmiDataId(4), DisplayName("Session Format Errors"): 
    amended, PerfDefault, CounterType(0x00010000),
    // PERF_COUNTER_RAWCOUNT
    DefaultScale(0), PerfDetail(100), read,
    Description("Count of Session format error"): amended]
    uint32  SessionFormatErrorCount;
  [WmiDataId(5),
    DisplayName("Sessions Failed"): amended, PerfDefault,
    CounterType(0x00010000),
    // PERF_COUNTER_RAWCOUNT
    DefaultScale(0), PerfDetail(100), read,
    Description("Number of Sessions failed belonging to this 
    instance"): amended] 
    uint32  SessionFailureCount;
};
