RESETSTATS Command
ZSTATS-UDP-CURR-TIME
is the time at which the TCP/IP process read the UDP Layer statistics
counters. This time indicates the end of the sample period.
ZSTATS-UDP-RESET-TIME
is the time at which the UDP Layer statistics counters were last reset. This time
indicates the beginning of the sample period.
ZTCI-MAP-IP-STATS
is the extensible structured token that lists the statistics counters maintained for the
IP Layer during the sample period. These statistics are returned only for the PROC
object. This token has the token number ZTCI-TNM-IP-STATS and the DDL
definition ZTCI-DDL-IP-STATS.
Each counter is defined in a separate field. The fields in the ZTCI-MAP-IP-STATS
token are:
ZSTATS-IP-TOTAL
is the number of incoming packets received by the IP Layer of TCP/IP
subsystem during the sample period.
ZSTATS-IP-BAD-XSUM
is the number of packets with an invalid checksum value received by the IP
Layer of the TCP/IP subsystem during the sample period. An invalid checksum
is usually caused by a noisy link.
ZSTATS-IP-TOO-SHORT
is the number of packets, received by the IP Layer of the TCP/IP subsystem
during the sample period, that contained less data than was specified in their
header. This can be caused by noisy links, a protocol error by the sender of the
packet, or a byte-swapping problem on the receiver.
ZSTATS-IP-TOO-SMALL
is the number of packets, received by the IP Layer of the TCP/IP subsystem
during the sample period, that contained less data than expected when read
into the local buffers. This error is rare; it usually indicates a problem with the
local machine’s buffering scheme.
ZSTATS-IP-BAD-HDR-LEN
is the number of packets received by the IP Layer of the TCP/IP subsystem
during the sample period with a header size that is larger than the header
length provided in the packet. This error is rare and indicates either a problem
with the sender of the packet, or a problem in reading the data from the link
controller to IP.
