It is the information about I/O operations to and from a server class. A send
operation is a message sent from the link manager to a server class process. A
reply operation is a message received by the link manager from a server class
process.
When an HTTPD process communicates with NSJSP, a single HTTPD message
sent to an NSJSP process results in multiple send operations from the link
manager to the process. This is because of the limitation on the maximum number
of bytes that can be sent in one send operation. Similarly, a single HTTP response
from the NSJSP Server Class process might result in multiple outgoing messages
between the process and the link manager.
Table 4-18 lists GUI the server class statistics.
Note. The communication between an HTTPD process and an NSJSP Server Class
process need not always happen through a link manager. If the session based load
balancing is turned on, HTTPD processes communicate with the NSJSP Server Class
processes directly through file system calls. In such a case, the link manager counters on
this page are not incremented.
