The Statistics Alerts view provides
details of statistical alerts that CICS® PA has
captured and loaded into the host DB2® database.
You can use the Statistics Alerts view to manage
and view single transactions, for example, on a day to day basis.
About this task
To view data trends in your system over a longer specified
period of time, you can view them in reports. See Working with reports.
You
can view statistics alerts in the CICS PA perspective and the CICS
SM perspective. If you are in the CICS SM perspective, you must also
be connected to the CICS PA database
to see data in this view.
You can display statistics alerts
that CICS PA has captured from CICS Transaction Server or CICS Transaction Gateway.
For
details about setting up statistics alert reporting on the CICS PA host, see Statistics alert reporting in CICS Performance
Analyzer product documentation.
Procedure
- To view statistics alerts, click the Statistics
Alerts tab
. By default, all
statistical 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, sort the data by column, or
filter the alerts, see Customizing the layout in the Sheet view.
- 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 a new tab in the sheet view. If a visualization is not available,
the Open menu option is not available and
double-clicking an alert displays details of the record that triggered
the alert in a new tab in the sheet view.
- To view the individual statistics record that triggered
an alert, right-click it then click Alert trigger on
the menu.
Details of the record that triggered the alert
are displayed in a new tab in the sheet view.
- To choose which types of statistics 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 statistics 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 statistics 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 create your own view of statistics records related to
an alert, right-click the alert then click Run using... on
the menu.
The "Extract from record type records" window
is displayed. The window title shows the type of record associated
with the selected statistics alert.
You can use this window
to select which statistics records to extract so that you can investigate
the circumstances that caused the alert. For example, you can extract
the statistics record that caused an alert, or the statistics records
for the period before an alert occurred, or statistics records to
use for comparison.
For example, an alert might be configured
to occur when the number of threads is 80. If this alert occurs, you
might set the time to see what the threads level was 10 minutes earlier.
Alternatively,
you might have two systems that are working in parallel. If an alert
occurs in one system, you might change the APPLID to see what the
corresponding statistic is on the other system. You might then decide
that you need to balance the systems better as a result.
You can use the following options in the Date
and time context section of the window:
- From date. Extract records from the specified
date and time to the end of the file.
- To date. Extract records from the first
input record to the specified date and time.
- From and to date. Extract records in the
date and time range specified in the Records from and Records
to fields.
- Exact date and time. Extract records with
the specified date and time.
- No date or time. Extract records using
an open-ended date and time range.
The extracted records are displayed in
a new tab in the sheet view.
- 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.
