TCP/IP Summary History Workspace
The TCP/IP Summary History workspace displays historical performance data
for the layers of the TCP/IP stack. This workspace displays the most recent
24 hours of historical data by default. This workspace can be displayed by
right-clicking on the TCP/IP Stack icon in the Navigator.
Short Term History support is an optional feature that must be enabled
for this workspace to display attribute and metric values. If this workspace
does not contain data, you will see message KFWITM220E Request failed
during execution. displayed in the Tivoli Enterprise Portal message
area. Contact your system administrator to request that historical collection
be started for this attribute group.
The following views provide information in this workspace:
- Telnet Session Count - This time line graph shows
a historical view of the number of active Telnet sessions for the specified
time period.
- Transmission Failures - This time line chart shows
a historical view of the percentage of transmission failures for the specified
time period, where:
- Yellow represents the input discard percentage
- Blue represents output discard percentage
- Pink represents the TCP retransmit percentage
- Green represents the UDP discard percentage
- Fragmentation and Reassembly - This time line chart
shows a historical view of the percentage of packet fragmentation and reassembly
for the specified time period, where:
- Yellow represents the reassembly percentage
- Blue represents reassembly failure percentage
- Pink represents the fragmentation percentage
- Green represents the fragmentation failure percentage
- Throughput Rate - This time line chart shows a historical
view of throughput expressed in bytes as a percentage of capacity for the
specified time period.
- CPU Utilization - This time line chart shows a historical
view of CPU utiliization expressed as a percentage of capacity for the specified
time period.
- TCP/IP Summary History Table - This summary table
provides detailed performance information about the TCP/IP stack displayed
in the charts on the TCP/IP Summary History workspace.
TCP/IP Summary History Table
The TCP/IP Summary History table provides detailed performance information
about the TCP/IP stack displayed in the charts on the TCP/IP Summary History
workspace for the specified time period.
The attributes displayed in the history workspaces represent a subset of
the attributes supported by the TCP/IP Summary workspace (for enhanced performance).
For a complete list of the attributes available in the TCP/IP Summary History
summary table, and a brief description of each, see the TCP/IP Address Space help panel. Because this is a history panel, a unique
attribute is listed in addition to the Interfaces attributes:
- Recording Time
- The time and date of the data sampling. Recording time displays the
exact collection interval boundary (such as every 00:15:00 minutes). This
value is displayed in the following format:
mm/dd/yy hh:mm:ss
Where:
- mm = Month
- dd = Day of the month
- yy = Year
- hh = Hour
- mm = Minute
- ss = seconds
