NAME

pppstats - print PPP statistics

SYNOPSIS

pppstats [ -a ] [ -v ] [ -r ] [ -z ] [ -c <count> ] [ -w <secs> ] [ interface ]

DESCRIPTION

The pppstats utility reports PPP-related statistics at regu- lar intervals for the specified PPP interface. If the inter- face is unspecified, pppstats defaults to sppp0. The display is split horizontally into input and output sections con- taining columns of statistics describing the properties and volume of packets received and transmitted by the interface. The pppstats utility is part of Solaris PPP 4.0, an imple- mentation of the Point-to-Point Protocol (PPP) that is based on the Australian National University PPP.

OPTIONS

The pppstats options are: -a Display absolute values rather than deltas. With this option, all reports show statistics for the time elapsed since the link was initiated. Without this option, the second and subsequent reports show statis- tics for the time since the last report. -c count Repeat the display count times. If this option is not specified, the default repeat count is 1 if the -w option is not specified, otherwise infinity. -r Display additional statistics summarizing the compres- sion ratio achieved by the packet compression algo- rithm in use. -v Display additional statistics relating to the perfor- mance of the Van Jacobson TCP header compression algo- rithm. -w wait Pause wait seconds between each display. If this option is not specified, the default interval is five seconds. -z Instead of the standard display, show statistics indi- cating the performance of the packet compression algo- rithm in use.

EXTENDED DESCRIPTION

The following fields are printed on the input side when the -z option is not used: IN Total number of bytes received by this interface. PACK Total number of packets received by this interface. VJCOMP Number of header-compressed TCP packets received by this interface. VJUNC Number of header-uncompressed TCP packets received by this interface. Not reported when the -r option is specified. VJERR Number of corrupted or bogus header-compressed TCP packets received by this interface. Not reported when the -r option is specified. VJTOSS 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. NON-VJ Total number of non-TCP packets received by this interface. Only reported when the -v option is speci- fied. RATIO 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. UBYTE 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: OUT Total number of bytes transmitted from this interface. PACK Total number of packets transmitted from this inter- face. VJCOMP Number of TCP packets transmitted from this interface with VJ-compressed TCP headers. VJUNC Number of TCP packets transmitted from this interface with VJ-uncompressed TCP headers. Not reported when SunOS 5.8 Last change: 4 May 2001 2 Maintenance Commands pppstats(1M) the -r option is specified. NON-VJ Total number of non-TCP packets transmitted from this interface. Not reported when the -r option is speci- fied. VJSRCH Number of searches for the cached header entry for a VJ header compressed TCP packet. Only reported when the -v option is specified. VJMISS Number of failed searches for the cached header entry for a VJ header compressed TCP packet. Only reported when the -v option is specified. RATIO 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. UBYTE 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 fol- lowing fields relating to the packet compression algorithm currently in use. If packet compression is not in use, these fields display zeroes. The fields displayed on the input side are: COMPRESSED BYTE Number of bytes of compressed packets received. COMPRESSED PACK Number of compressed packets received. INCOMPRESSIBLE BYTE Number of bytes of incompressible packets (that is, those which were transmitted in uncompressed form) received. INCOMPRESSIBLE PACK Number of incompressible packets received. COMP RATIO Recent compression ratio for incoming packets, defined as the uncompressed size divided by the compressed size (including both compressible and incompressible packets). SunOS 5.8 Last change: 4 May 2001 3 Maintenance Commands pppstats(1M) The fields displayed on the output side are: COMPRESSED BYTE Number of bytes of compressed packets transmitted. COMPRESSED PACK Number of compressed packets transmitted. INCOMPRESSIBLE BYTE Number of bytes of incompressible packets received; that is, those that were transmitted by the peer in uncompressed form. INCOMPRESSIBLE PACK Number of incompressible packets transmitted. COMP RATIO Recent compression ratio for outgoing packets.
