Queue Info
Server statistics show the amount of link manager resources used to communicate
with a server class. Server statistics collected by LINKMON processes or ACS
subsystem processes, and TCPs provide information about:
•
Server-class wait queue (QUEUE INFO)
•
Input and output operations (I/OþINFO)
Example 7-1 shows a sample set of server statistics gathered by a TCP (TCP1) and a
LINKMON process (LM1).
Note that neither the LINKMON process nor the TCP generate values for the REPLY
REQ CNT and REPLY I/O CNT fields. Note also the inclusion of Response Time Info.
These statistics are collected only the TCP. See Response Time Info.
Queue Info
The QUEUE INFO section in the statistics display provides information about the
server-class wait queue.
This queue is for SEND operations that the link manager, that is, the LINKMON
process, ACS subsystem processes, or TCP, cannot run 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.
Example 7-2 shows only the QUEUE INFO section of the sample server statistics. See
this figure as you read this section.
