ZIOS
is the number of I/O operations to the servers in this server class. For sends, this
value is always the same as the ZREQCNT value.
ZREPLY
reports information about REPLY statements from the server class. ZREPLY contains:
ZREQCNT
is when statistics are not provided for REPLY statements because there are no explicit
requests for REPLY.
ZMAXSIZE
is the size, in bytes, of the largest amount of data transferred in a reply from the
server class during the interval that the link manager reports these statistics.
ZAGGREGATESIZE
is the total size, in bytes, of the data transferred in a reply from the server class for
the interval that the link manager reports these statistics. To find the average size,
divide ZAGGREGATESIZE by ZIOS.
ZIOS
is when statistics are not provided for REPLY statements because there are no explicit
requests for REPLY.
ZPERFINFO
provides measurements on the completion of SCREEN COBOL SEND statements.
As this information is collected and reported only by the Pathway/iTS TCP, this field
is relevant only if you are using the Pathway/iTS product.
The measurements are gathered by the Pathway/iTS TCP for the servers to which
it has links; measurement collection begins at TCP initialization when the ZSTATS
field has the value ZPWY-VAL-ON. As operations proceed, measurements are
captured by starting and stopping internal clocks at initiation and termination of
SEND statements.
The limits imposed on measurement collection are:
• Measurements will stop for any server upon the 99,999,999th measurement.
• Any measurement greater than 99,999,999.99 seconds is discarded.
• After a measurement counter reaches 99,999,999.99 seconds,
measurement-collection for this server class stops.
• Response times are reported in microseconds.
For additional information on performance statistics, see the Pathway/iTS System
Management Manual.
NOTE: ACS subsystem processes do not collect or report data for the RESPONSE
TIME INFO section of the STATS SERVER display; only TCPs collect or report this
data. Consequently, if your environment is mixed (that is, both Pathway/iTS TCPs
and TS/MP ACS subsystem processes), the statistics reported might provide only a
partial view of server class performance.

ZAGGREGATE
reports information on response time. It contains:
