where:

• start is the time statistics collection started. This field indicates the date or time that the statistics were last cleared; that is, it indicates the time period over which the returned statistics were collected.

• numNCB fields indicate the number of network control blocks (NCBs) issued from each source and include failed NCBs. To get the total number of successful NCBs issued, subtract the number of failed NCBs. These numbers are held as follows in the fcNCB fields:

  • numNCB_r is the number of NCBs issued (redirector).
    
  • numNCB_s is the number of NCBs issued (server).
    
  • numNCB_a is the number of NCBs issued (application).
  
  fiNCB fields indicate the number of NCBs that failed at the time they were issued, for whatever reason. These counts are included in the total number of NCBs issued, as follows:

  • fiNCB_r is the number of NCBs that failed issue (redirector).
    
  • fiNCB_s is the number of NCBs that failed issue (server).
    
  • fiNCB_a is the number of NCBs that failed issue (application).
  
  fcNCB fields indicate the number of NCBs that failed after issue, whether at or before completion. These counts are included in the total number of NCBs issued, as follows:

  • fcNCB_r is the number of NCBs that failed completion (redirector).
    
  • fcNCB_s is the number of NCBs that failed completion (server).
    
  • fcNCB_a is the number of NCBs that failed completion (application).
  
  sesstart is the number of requester sessions started.
  
  sessfailcon is the number of requester session failures to connect, except those that failed because of name not found.
  
  sessbroke is the number of failures of requester sessions, after the sessions were established.
  
  uses is the number of requester uses.
  
  usefail is the number of requester use failures. This is a count of failed tree-connects, when a server is found but the resources were not found.
  
  autorec is the number of requester autoconnects.
  
  The following 12 fields form six quadwords, which contain very large counters. The high doubleword of each is the value divided by 2[32], while the low doubleword is the value modulo 2[32]. A quadword is a data area that is twice as large as a doubleword.

  These fields count total bytes in all NCBs sent and received for all three categories: issued, failed issue, and failed completion. Server information is included to provide an accurate total.

  Note: For all the NCB-related and bytes-count counters:

  Those with the suffix _r are from the redirector. These NCBs are issued by the redirector as part of the normal process of maintaining remote network connections.

  Those with the suffix _s are server-related. These NCBs are sent by the redirector on behalf of the server to maintain shared resource connections.

  Those with the suffix _a are application-generated. These NCBs can be caused by applications calling NetBiosSubmit, the use of second-class mailslots, server announcements (sending and receiving), and so on.

  • bytessent_r_hi is the number of requester bytes sent to the network (high doubleword).

  • bytessent_r_lo is the number of requester bytes sent to the network (low doubleword).

  • bytesrcvd_r_hi is the number of requester bytes received from the network (high doubleword).

  • bytesrcvd_r_lo is the number of requester bytes received from the network (low doubleword).

  • bytessent_s_hi is the number of server bytes sent to the network (high doubleword).

  • bytessent_s_lo is the number of server bytes sent to the network (low doubleword).

  • bytesrcvd_s_hi is the number of server bytes received from the network (high doubleword).

  • bytesrcvd_s_lo is the number of server bytes received from the network (low doubleword).

  • bytessent_a_hi is the number of application bytes sent to the network (high doubleword).

  • bytessent_a_lo is the number of application bytes sent to the network (low doubleword).

  • bytesrcvd_a_hi is the number of application bytes received from the network (high doubleword).

  • bytesrcvd_a_lo is the number of application bytes received from the network (low doubleword).
  
  reqbufneed is the number of times the requester required a request buffer but failed to allocate one. This indicates that the parameters of the requester might need adjustment.
  
  bigbufneed is the number of times the requester required a big buffer but failed to allocate one. This indicates that the parameters of the requester might need adjustment.

  Note: A value of -1 or 0xFFFFFFFF for any field means that information is not available. A value of -2 or 0xFFFFFFFE means that the field has overflowed.
