Queue Info
•
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 on page 7-5.
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 or 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.
Example 7-2 shows only the QUEUE INFO section of the sample server statistics. See
this figure as you read this section.
