TS/MP 2.5 Management Programming Manual

reports the time at which statistics were collected.
ZQUEUEINFO
reports statistics about the server class wait queue. This queue usually holds send
operations that the link manager (such as ACS subsystem processes, or Pathway/iTS
TCP) cannot execute immediately because a link to the server class is not available.
Server class requests wait in the link manager until an existing link becomes available
or until the PATHMON process grants a new link. ZQUEUEINFO contains:
ZREQCNT
is the number of requests to the server class that cannot be satisfied immediately.
ZWAITS
is the total number of send requests that the link manager queued when one or
more other requests were already queued for the server class. To find the percentage
of send requests that waited, multiply ZWAITS by 100 and divide the result by
ZREQCNT.
ZMAXWAITS
is the greatest number of requests that were waiting in the queue for a link before
the link manager added another send request to the queue. This value is one greater
than the number returned because the request being added was not counted.
ZAGGREGATEWAITS
is the total number of requests that were waiting in the queue when the link manager
added another send request to the queue. To find the average number of requests
that were waiting, divide ZAGGREGATEWAITS by ZREQCNT.
ZDYNAMICLINKS
is the number of requests for the server class that are in the link manager’s queue
and have a ZCREATEDELAY timeout value. These requests wait in the link manager
until an existing link becomes available or until the PATHMON process grants a
new link. To find the percentage of dynamic links that are waiting, multiply
ZDYNAMICLINKS by 100 and divide the result by ZREQCNT.
ZIOINFO
reports the statistics about I/O operations to and from the server class. These I/O
operations are the result of the SEND and REPLY statements used to communicate
with the server. ZIOINFO contains:
ZSEND
reports information about the SEND statements to the server class. ZSEND contains:
ZREQCNT
is the total number of send statements to servers in the server class.
ZMAXSIZE
is the size, in bytes, of the largest amount of data transferred in a send statement
during the interval that the link manager reports these statistics.
ZAGGREGATESIZE
is the total size, in bytes, of the data transferred in a send statement during the
interval that the link manager reports these statistics. To find the average size, divide
ZAGGREGATESIZE by ZIOS.
