.SH DESCRIPTION
+The
.B pppstats
-prints PPP-related statistics.
+utility reports PPP-related statistics at regular intervals for the
+specified PPP interface. If the interface is unspecified, it will
+default to ppp0.
+The display is split horizontally
+into input and output sections containing columns of statistics
+describing the properties and volume of packets received and
+transmitted by the interface.
.PP
-The
+The options are as follows:
+.TP
+.B -a
+Display absolute values rather than deltas. With this option, all
+reports show statistics for the time since the link was initiated.
+Without this option, the second and subsequent reports show statistics
+for the time since the last report.
+.TP
+.B -c \fIcount
+Repeat the display
+.I count
+times. If this option is not specified, the default repeat count is 1
+if the
+.B -w
+option is not specified, otherwise infinity.
+.TP
+.B -r
+Display additional statistics summarizing the compression ratio
+achieved by the packet compression algorithm in use.
+.TP
.B -v
-flag causes
-.B pppstats
-to display additional statistics, such as the number of packets tossed
-(that is, which the VJ TCP header decompression code rejected).
+Display additional statistics relating to the performance of the Van
+Jacobson TCP header compression algorithm.
+.TP
+.B -w \fIwait
+Pause
+.I wait
+seconds between each display. If this option is not specified, the
+default interval is 5 seconds.
+.TP
+.B -z
+Instead of the standard display, show statistics indicating the
+performance of the packet compression algorithm in use.
.PP
-The
+The following fields are printed on the input side when the
+.B -z
+option is not used:
+.TP
+.B IN
+The total number of bytes received by this interface.
+.TP
+.B PACK
+The total number of packets received by this interface.
+.TP
+.B VJCOMP
+The number of header-compressed TCP packets received by this interface.
+.TP
+.B VJUNC
+The number of header-uncompressed TCP packets received by this
+interface. Not reported when the
.B -r
-flag causes
-.B pppstats
-to display the overall packet compression rate. The rate value is
-between 0 and 1, with 0 meaning that the data is incompressible.
+option is specified.
+.TP
+.B VJERR
+The number of corrupted or bogus header-compressed TCP packets
+received by this interface. Not reported when the
+.B -r
+option is specified.
+.TP
+.B VJTOSS
+The number of VJ header-compressed TCP packets dropped on reception by
+this interface because of preceding errors. Only reported when the
+.B -v
+option is specified.
+.TP
+.B NON-VJ
+The total number of non-TCP packets received by this interface. Only
+reported when the
+.B -v
+option is specified.
+.TP
+.B RATIO
+The compression ratio achieved for received packets by the
+packet compression scheme in use, defined as the uncompressed size
+divided by the compressed size.
+Only reported when the
+.B -r
+option is specified.
+.TP
+.B UBYTE
+The total number of bytes received, after decompression of compressed
+packets. Only reported when the
+.B -r
+option is specified.
.PP
-The
-.B -c
-flag is used to specify an alternate display mode that shows
-packet compression statistics: the number of packets and bytes
-uncompressed (that is, before compression or after decompression),
-compressed, and incompressible (packets which did not shrink on
-compression and were transmitted uncompressed), and the recent
-compression rate. This rate reflects the recent performance of the
-compression code rather than the overall rate achieved since
-compression was enabled.
+The following fields are printed on the output side:
+.TP
+.B OUT
+The total number of bytes transmitted from this interface.
+.TP
+.B PACK
+The total number of packets transmitted from this interface.
+.TP
+.B VJCOMP
+The number of TCP packets transmitted from this interface with
+VJ-compressed TCP headers.
+.TP
+.B VJUNC
+The number of TCP packets transmitted from this interface with
+VJ-uncompressed TCP headers.
+Not reported when the
+.B -r
+option is specified.
+.TP
+.B NON-VJ
+The total number of non-TCP packets transmitted from this interface.
+Not reported when the
+.B -r
+option is specified.
+.TP
+.B VJSRCH
+The number of searches for the cached header entry for a VJ header
+compressed TCP packet. Only reported when the
+.B -v
+option is specified.
+.TP
+.B VJMISS
+The number of failed searches for the cached header entry for a
+VJ header compressed TCP packet. Only reported when the
+.B -v
+option is specified.
+.TP
+.B RATIO
+The compression ratio achieved for transmitted packets by the
+packet compression scheme in use, defined as the size
+before compression divided by the compressed size.
+Only reported when the
+.B -r
+option is specified.
+.TP
+.B UBYTE
+The total number of bytes to be transmitted, before packet compression
+is applied. Only reported when the
+.B -r
+option is specified.
.PP
-The
-.B -i
-flag is used to specify the interval between printouts. The default is
-5 seconds.
+When the
+.B -z
+option is specified,
+.Nm pppstats
+instead displays the following fields, relating to the packet
+compression algorithm currently in use. If packet compression is not
+in use, these fields will all display zeroes. The fields displayed on
+the input side are:
+.TP
+.B COMPRESSED BYTE
+The number of bytes of compressed packets received.
+.TP
+.B COMPRESSED PACK
+The number of compressed packets received.
+.TP
+.B INCOMPRESSIBLE BYTE
+The number of bytes of incompressible packets (that is, those which
+were transmitted in uncompressed form) received.
+.TP
+.B INCOMPRESSIBLE PACK
+The number of incompressible packets received.
+.TP
+.B COMP RATIO
+The recent compression ratio for incoming packets, defined as the
+uncompressed size divided by the compressed size (including both
+compressible and incompressible packets).
.PP
-<unit#> specifies which interface to use for gathering statistics.
+The fields displayed on the output side are:
+.TP
+.B COMPRESSED BYTE
+The number of bytes of compressed packets transmitted.
+.TP
+.B COMPRESSED PACK
+The number of compressed packets transmitted.
+.TP
+.B INCOMPRESSIBLE BYTE
+The number of bytes of incompressible packets transmitted (that is,
+those which were transmitted in uncompressed form).
+.TP
+.B INCOMPRESSIBLE PACK
+The number of incompressible packets transmitted.
+.TP
+.B COMP RATIO
+The recent compression ratio for outgoing packets.
