pppstats - Print Point-to-Point Protocol (PPP) statistics
/usr/sbin/pppstats [-a] [-v] [-r] [-c count] [-w secs]
[interface] [-z]
Displays 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. Repeats the display count times. The
default repeat count is 1 if the -w option is not specified,
otherwise infinity. Displays the overall packet
compression rate. The rate value is between 0 and 1, with
0 meaning that the data is incompressible. Displays additional
statistics, such as the number of packets ignored
(rejected by the VJ TCP header decompression code).
Pauses wait seconds between each display. If this option
is not specified, the default interval is 5 seconds.
Instead of the standard display, show statistics indicating
the performance of the packet compression algorithm in
use. See the STATISTICS section for further information on
this option.
The pppstats utility reports PPP-related statistics at
regular intervals for the specified PPP interface. If
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.
STATISTICS [Toc] [Back]
The following fields are printed on the input side when
the -z option is not used: The total number of bytes
received by this interface. The total number of packets
received by this interface. The number of header-compressed
TCP packets received by this interface. The number
of header-uncompressed TCP packets received by this
interface. Not reported when the -r option is specified.
The number of corrupted or bogus header-compressed TCP
packets received by this interface. Not reported when the
-r option is specified. The number of VJ header-compressed
TCP packets dropped on reception by this interface
because of preceding errors. Only reported when the -v
option is specified. The total number of non-TCP packets
received by this interface. Only reported when the -v
option is specified. 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 -r option is specified. The
total number of bytes received, after decompression of
compressed packets. Only reported when the -r option is
specified.
The following fields are printed on the output side: The
total number of bytes transmitted from this interface.
The total number of packets transmitted from this
interface. The number of TCP packets transmitted from
this interface with VJ-compressed TCP headers. The number
of TCP packets transmitted from this interface with VJuncompressed
TCP headers. Not reported when the -r option
is specified. The total number of non-TCP packets transmitted
from this interface. Not reported when the -r
option is specified. The number of searches for the
cached header entry for a VJ header compressed TCP packet.
Only reported when the -v option is specified. The number
of failed searches for the cached header entry for a VJ
header compressed TCP packet. Only reported when the -v
option is specified. 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 -r option is specified.
The total number of bytes to be transmitted,
before packet compression is applied. Only reported when
the -r option is specified.
When the -z option is specified, pppstats displays the
following fields, relating to the packet compression algorithm
currently in use. If packet compression is not in
use, these fields all display zeroes. The fields displayed
on the input side are: The number of bytes of compressed
packets received. The number of compressed packets
received. The number of bytes of incompressible packets
(that is, those which were transmitted in uncompressed
form) received. The number of incompressible packets
received. The recent compression ratio for incoming packets,
defined as the uncompressed size divided by the compressed
size (including both compressible and incompressible
packets).
The fields displayed on the output side are: The number of
bytes of compressed packets transmitted. The number of
compressed packets transmitted. The number of bytes of
incompressible packets transmitted (that is, those which
were transmitted in uncompressed form). The number of
incompressible packets transmitted. The recent compression
ratio for outgoing packets.
