The Transaction Performance Alerts view
provides details of performance alerts that CICS® PA has captured from CICS Transaction Server and loaded into the
host DB2® database. You can use
this view to monitor and report significant transaction performance
conditions that are based on predefined thresholds. You can monitor CICS transactions for performance
compliance, including service level monitoring, and problem detection.
About this task
User-defined thresholds are set for specified CMF performance
data in the performance alert definition on the CICS PA host. For details, see Performance alerts in CICS Performance Analyzer
product documentation.
The CMF performance
data for transactions that might cause an alert is compared with the
defined thresholds, and any transactions that exceed the threshold
values are reported. Performance alerts are reported by severity.
Procedure
- To view performance alerts, click the Transaction
Performance Alerts tab
. By default, all performance alerts
in the CICS PA database for
the currently selected APPLID are displayed. If the view does not
update, use the Link to Selection icon
in the toolbar of the view. You can also reduce the scope
of the displayed alerts. See Refining the data selection.
- To change the column layout or sort the data by column,
see Customizing the layout in the Sheet view.
- To filter the alerts, see Writing a freeform filter.
- If a visualization is available for an alert, to view that
visualization, either double-click the required alert, or right-click
it then click Open on the menu.
The visualization is
displayed in the Transaction performance detail view
and shows the tab for the pie chart relevant to the selected alert
field. If a visualization is not available, the Open menu
option is not available and double-clicking an alert displays details
of the performance list record that triggered the alert in a new tab
in the sheet view.
- To view the individual record that triggered an alert,
right-click it then click Alert trigger on
the menu.
Details of the performance list record that
triggered the alert are displayed in a new tab in the sheet view,
with the relevant layout applied. For example, for a SUSPEND alert,
the Suspend time analysis layout is applied. If the alert field does
not have a relevant layout associated with it, the All fields layout
is applied.
- To choose which types of performance alerts to display,
click the View Menu icon
in the toolbar of the view, then click the
alert type you require on the menu. You can select one
of the following options:
- Critical
- Warning
- Information
- To display performance alerts from a general time period,
click the arrow on the Performance Analyzer date dialog icon
on the toolbar, then click the required time period
on the menu. You can select one of the following options:
- Yesterday. All alerts that occurred in
the last 24 hours are displayed, relative to the current day.
- Week. All alerts that occurred in exactly
the last seven days are displayed.
- Month. All alerts that occurred in the
last calendar month are displayed.
- Quarter. All alerts that occurred in the
last three calendar months are displayed.
- Year. All alerts that occurred in the last
year are displayed.
- To display performance alerts from a specific time period,
click the Performance Analyzer date dialog icon
on the toolbar to display the Date-time
selection window. For information about using
this window, see Refining the data selection.
- To hide an alert in the CICS PA perspective, right-click
it and click Hide alert on the menu.
You
can use the Shift and Ctrl keys to select multiple alerts. The selected
alerts are hidden from view and the local copies are deleted from
the cache. The alerts remain on the PA host database, which has a
full dataset available (containing other alerts that you might have
hidden). To delete an alert permanently, you must delete in on the
host. To view hidden alerts again, click the Refresh icon
on
the toolbar.
- To set the number of alerts retrieved in the Alerts views,
click the View Menu icon
in the toolbar of the view, then click Alert
preferences. See CICS Performance Analyzer Preferences.
