12.1.1.4 Using the RTM Table
The Sun PU2.1 SNA Server allows a NetView operator to initiate the
measurement of response time statistics for selected 3270 display devices. The
server accumulates RTM statistics for the devices and delivers the statistics to
NetView on demand or on session termination. sun3270 clients measure both
SNA and TCP/IP response times. TN3270 clients can include the round-trip
TCP/IP time using the Telnet Timing Mark option. Response time information
is maintained separately for the SNA and TCP/IP networks.
Note – The Sun PU2.1 SNA Server also supports Network Performance
Monitor (NPM) response time measurements for sun3270 and TN3270 clients.
NPM uses definite response mode to measure round-trip delay. Since only
extended TN3270E clients can handle definite responses, for traditional
TN3270 clients, you must use the Telnet Timing Mark option to configure the
server to delay transmission of the definite response until the client has
received the request.
If an RTM table format is defined for a dependent LU, you can display an RTM
table by highlighting the dependent LU in the resource tree and selecting
Display
→
RTM . The particular information displayed and the headings used
for that information depend on the way you set up your status table format.
For more information, refer to Section 12.1.1.2, “Customizing a Table Format,”
on page 12-2.
The following table describes the MIB variables that you can use in an RTM
table for dependent LUs.
