TN3270 Server Session Details Workspace
The TN3270 Session Details workspace displays performance data
for the active or completed TN3270 server session with a specified
connection number. In order to be displayed, performance data must
have been collected for this session within the TN3270 display interval
(by default, last 2 hours). This workspace displays an active session
(sliding window and bucket count metrics are collected for these sessions
each collection interval) or a session opened or closed within the
TN3270 display interval.
This workspace is displayed by right-clicking on a link for a TN3270
session in one of the following workspaces:
- TN3270 Server Sessions
- TN3270 Server Session Pair
- TN3270 Server Sessions for Remote IP
- TN3270 Server Sessions for SNA Name
This workspace contains the following views:
- TN3270 Server Session Response Time: Displays
a line graph, graphed over time, where:
- Yellow represents the Average Total Response
Time.
- Blue represents the Average IP Response
Time.
- Pink represents the Average SNA Response
Time.
- TN3270 Server Session Throughput: Displays
Total Bytes Sent and Total Bytes Received in a stacked bar chart graphed
against Connection ID where:
- Blue designates the Total Bytes Sent.
- Yellow designates the Total Bytes Received.
- TN3270 Server Session Response Time Bucket Counts:
Displays the count of transactions falling into each of the response
time buckets. For a complete list of the attributes available in the
TN3270 Server Session Response Time Bucket Counts view, and a brief
description of each, see the TN3270 Response Time Buckets Attributes help panel.
- TN3270 Server Session Details for xxx Summary
Table:
Provides a tabular summary of all the available performance data for
active or completed TN3270 server sessions from the specified remote
IP address, where xxx is the specified remote
IP address.
For additional information about sliding windows, see the IBM z/OS Communications Server: IP Configuration Guide. This view will not have data when historical data is viewed
in this workspace.
TN3270 Server Session Details for xxx Summary
Table
The TN3270 Server Session Details for xxx Summary
Table displays performance data for a specific session (identified
by a Connection Number). The displayed session has a collection time
within the TN3270 display interval (by default, last 2 hours).
The following attributes are presented in this table:
- Response Times Counts for Bucket 1 through 5:
the count of response times falling into the specified bucket.
- Response Times Percent for Bucket 1 through 5:
the percentage of the total count of response times falling into the
specified bucket.
- Upper Boundaries for Bucket 1 through 4:
where:
- Bucket 1 Upper Boundary is the range of transaction response times
counted in Bucket 1 (those less than or equal to this value).
- Bucket 2 Upper Boundary, together with Bucket 1 Upper Boundary,
defines the range of transaction response times counted in Bucket
2 (those greater than the value of Bucket 1 upper boundary and less
than or equal to the value in this field).
- Bucket 3 Upper Boundary, together with Bucket 2 Upper Boundary,
defines the range of transaction response times counted in Bucket
3 (those greater than the value of Bucket 2 upper boundary and less
than or equal to the value in this field).
- Bucket 4 Upper Boundary, together with Bucket 3 Upper Boundary,
defines the range of transaction response times counted in Bucket
4 (those greater than the value of Bucket 3 upper boundary and less
than or equal to the value in this field). This field also defines
the range of transaction response times counted in Bucket 5 (those
greater than this field).
Clicking on the Link icon for the displayed
session (the default link) takes you to the TCP Connections Workspace.
For a complete list of the attributes available in the TN3270 Server
Session Summary table, and a brief description of each, see the TN3270 Server Sess Avail Attributes help panel. For additional information sliding
windows and response times, see the IBM(R) z/OS(R) Communications Server: IP Configuration Guide.
