NAME

       pfstat - Print packet filter status information

SYNOPSIS

       /usr/bin/pfstat [options]

OPTIONS

       If no options are given, all are assumed (except for the verbose option, -v).  Counts.  Displays various counts (per ethernet unit) includ-
       ing number of packets sent and received, the number of packets dropped due to full input queues, the number of packets not  wanted  by  any
       filter,	and  the number of packets missed by the interface.  Descriptors.  Displays OpenDescriptors for each minor device.  Filters.  Dis-
       plays packet filters for each minor device.  Parameters.  Displays device parameters including device type,  header  and  address  lengths,
       maximum transmission units (MTU), and interface and broadcast addresses.  QueueElements.  Displays the QueueElements.  Scavenger.  Displays
       the FreeQueue and Scavenger statistics.	Verbose.  Displays information for minor devices not actually in use and complete  queue  informa-
       tion,  only if this option is given.  Limits output to information about specified units.  If no digits are given, all units are displayed.
       Valid digits are 0 to 7.

DESCRIPTION

       The pfstat command interprets the data structures of the packet filter driver  packetfilter(7).	 The  data  structures	are  contained	in
       /dev/kmem.

RESTRICTIONS

       By  default,  some  of  the output might not be easily read on an 80-character line.  You might want to use some of the options to obtain a
       less verbose but more readable listing.

       Because of the dynamic nature of a running system, pfstat might not provide a consistent view of the system.  You should use  this  command
       for analyzing static or slowly-varying problems, not transient ones.

OUTPUT FORMAT

       This  section  describes  the  information  displayed  in  the output of the pfstat command under the headings AllDescriptors, Filters, and
       QueueElts.

   AllDescriptors
       Minor device number for open descriptor.  Descriptor location.  Forward link to other descriptors.  Blank, or one of the following: Waiting
       for  input,  indefinite	wait  Waiting  for input, timed wait Has timed out Addresses of ``Queue Elements'' for waiting packets.  Number of
       packets queued for input/maximum for this queue.  Timeout duration in clock ticks (if the -v [Verbose] option is not given, the	times  may
       be  expressed  as minutes [with a trailing ``m''], hours [with a trailing ``h''], or simply ``long'', to keep the columns lined up.)  Shows
       which mode bits are set for the minor device; each bit is encoded as a single character: ENHOLDSIG  ENBATCH  ENTSTAMP  ENPROMISC  ENNONEXCL
       ENCOPYALL  ENBPFHDR An unknown mode bit is set.	Signal number to be delivered when a packet arrives.  Process to be signaled when a packet
       arrives.  Process id which enabled the signal.

   Filters
       Minor device number of filter.  Count of packets accepted by this filter.  Count of ``recent'' drops for this filter.  Priority of  filter.
       (Not  applicable  to BPF-style filters.)  Length of filter (in shortwords).  See packetfilter(7) for interpretation of packet filters.  See
       bpf(7) for interpretation of BPF-style filters.

   QueueElts
       Location of queue element.  Forward and backward links.	Packet size.  Reference count for queue element.  Per-packet flag bits	set;  each
       bit is encoded as a single character: ENSF_PROMISC ENSF_BROADCAST ENSF_MULTICAST ENSF_TRAILER An unknown flag bit is set.  Count of packets
       dropped between the time previous packet was queued and the time this packet was queued.  Approximate time this packet was received.
