STATISTICS Command
ZSTATS-TCP-RCV-WIN-UPDATE
the number of window update packets received.
ZTCI-MAP-UDP-STATS
is the extensible structured token that lists the statistics counters maintained for the
UDP Layer during the sample period. These statistics are returned only for the
PROC object. This token has the token number ZTCI-TNM-UDP-STATS and the
DDL definition ZTCI-DDL-UDP-STATS.
Each counter is defined in a separate field. The fields in the ZTCI-MAP-UDP-
STATS token are:
ZSTATS-UDP-BAD-HDR-LEN
is the number of packets with an invalid header size received by the UDP
Layer of the TCP/IP subsystem during the sample period. This error is very
rare; it usually indicates a problem between IP and UDP.
ZSTATS-UDP-BAD-XSUM
is the number of packets with an invalid checksum value received by the UDP
Layer of the TCP/IP subsystem during the sample period. An invalid checksum
is usually caused by a noisy link.
ZSTATS-UDP-BAD-LEN
is the number of packets received by the UDP Layer of the TCP/IP subsystem
during the sample period that contain either more or less data than has been
specified in their header. This error is rare; it usually indicates that the sender
has a protocol error or that the receiver has a byte-ordering problem.
ZSTATS-UDP-IN-PKTS
is the number of incoming packets received by the UDP Layer of the TCP/IP
subsystem during the sample period.
ZSTATS-UDP-OUT-PKTS
is the number of outgoing packets sent by the UDP Layer of the TCP/IP
subsystem during the sample period.
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
indicates the beginning of the sample period.
