You can display the suspend time for a transaction as a
pie chart for analysis.
Pie charts
Pie charts are displayed in
the Transaction detail view and show detailed information about a
single transaction ID.
To display a Transaction detail view,
see the Pie charts section
in the Analyzing data topic.
The Transaction detail view displays
a pie chart for each type of analysis. Each analysis can be selected
by clicking the relevant pie chart. The following screen capture shows
the Transaction detail view with the suspend time pie chart selected.
The suspend time analysis
displays the following information:
- A summary of the wait time for the selected transaction in the
time period chosen. In the example screen capture, the summary shows
the following information:
- No I/O wait time for transaction CATD occurred during the selected
time period.
- An average of 0.000016 seconds wait at first dispatch
- An average of 0.000028 seconds wait during TCB mode switch.
- A pie chart consisting of three sectors, one for each type of
suspend time: I/O, Other and uncaptured.
- A table containing a list of the suspend time fields in the view,
their values and percentage of the total suspend time, and a further
breakdown of the fields. Clicking a sector in the pie chart highlights
the relevant entry in the table.
By selecting one or more of the check boxes in the view
you can choose to hide irrelevant data from the table.
Note: The
values displayed in the table are the actual values from the CSV file.
Rounding errors when the data was captured mean that the sum of the
detail might not match the total value. In addition, the percentage
figures might not total 100% because of rounding errors.
Suspend
time breaks down into the following three fields:
- I/O wait time, which in turn breaks down into the following fields:

- Outbound socket I/O wait time
- Inter-region wait time
- LU61 I/O wait time
- LU62 I/O wait time
- FEPI I/O wait time
- Other wait time which in turn breaks down into the following fields:
- First dispatch delay time
