Server Statistics Collected Only By the TCP
REQ CNT
Statistics are not provided for REPLY statements because there are no explicit
requests for REPLY.
I/O CNT
Statistics are not provided for REPLY statements because there are no explicit
requests for REPLY.
Server Statistics Collected Only By the TCP
Server statistics show the amount of link manager resources used to communicate
with a server class. Only TCPs collect server statistics that provide information about:
•
Response time (RESPONSE TIME INFO)
•
Frequency distribution (optional)
These statistics are collected only if your environment includes the Pathway/iTS
product.
Response Time Info
The RESPONSE TIME INFO section of the statistics display provides information
about the completion of SCREEN COBOL SEND statements.
The measurements are gathered by the TCP for the servers with which it has links. As
operations proceed, the TCP captures each measurement by starting an internal clock
Table 7-2. Server Statistics for I/O Info
Statistic For SEND, Indicates: For REPLY, Indicates:
REQ CNT Total number of sends to servers
in this server class
N.A.
MAX TSIZE Size, in bytes, of the largest
amount of data transferred in a
send
Size, in bytes, of the largest amount of
data transferred in a reply from the
server class
AVG TSIZE Size, in bytes, of the average
amount of data transferred during
a send
Size, in bytes, of the average amount
of data transferred in a reply from the
server class. This size can be used to
fine tune the amount of server pool
space required.
I/O CNT Number of I/O operations to
servers of this server class
(For SEND commands, I/O CNT is
always the same as the REQ
CNT.)
