NAME

sestat − print Ethernet statistics

SYNOPSIS

/usr/etc/sestat [ −z ] [ system [ corefile ] ]

DESCRIPTION

Sestat prints summary statistics about the Ethernet interface se. If corefile is given, the statistics are sought there, otherwise in /dev/kmem. The required namelist is taken from /dynix unless system is specified.  Options are

−z After printing the statistics, zero them in corefile. This is useful for monitoring the health of the network over short periods of time. You must be the super-user to do this.

Statistics printed by sestat are summaries since the last boot (or the last sestat -z), and are printed for all se interfaces.  The statistics printed are:

-The number of times the receiver couldn’t keep up with the network (receiver overflows). 

-The number of packets received with CRC errors. 

-The number of packets received with dribble errors (the hardware compensates for these errors). 

-The number of short packets received. 

-The number of good packets received (includes the dribble errors). 

-The number of times the transmitter didn’t keep up with the tranmit DMA (transmit underflows). 

-The number of transmit collisions (usually in the same range as transmit underflows). 

-The number of excessive transmit collisions (16 collisions in a row). 

-The number of good packets transmitted.

BUGS

There is no way to zero the statistics for a single Ethernet interface.
