When a condition evaluates to true, the system tracks its occurrence and automatically creates a condition alert. This section explains the various ways Business Transaction Management displays count and condition alert information, and it explains how you can modify the amount of time that alerts are stored.
You cannot manually delete alerts.
You can view count information condition alerts as follows:
In the Operational Health Summary dashboard (counts for each type of alert).
In the Top 10 Transactions dashboard.
In the Alerts tab of a transaction.
In the Performance pane of the Analysis tab for the transaction.
In the Conditions pane of the Analysis tab for the transaction.
You can also edit the summary view (for a transaction) to show a count of condition alerts and the current condition alert rate by using the column chooser and selecting the Condition alert and Condition alert rate instruments. The Condition alert instrument specifies the condition occurrences in the specified period. The Condition alert rate instrument specifies the number of condition occurrences per hour in the given period.
You can view condition alerts in the following ways:
on the Alerts tab of the related service, endpoint, operation, or transaction instance. Detailed information for the selected alert is shown in a separate window if you click the looking glass icon or double click the alert
in the Condition Alerts view from the navigator for condition alerts that occurred in the last hour. Detailed information for the selected alert is shown in the Info tab in the tab area.
Condition alert detail includes the following information:
the name and severity of the condition and the expression whose evaluation triggered the alert.
summary information: The name of the transaction, the time it was captured (Start Time), its ID, the number of message exchanges and the total messages, the response time for the transaction, and any conditions alerts raised while the transaction executed (with severity flags shown).
a graph of the transaction, showing the operation for which the condition expression evaluated to true with a red broken arrow. To display the request and response message for each operation, click the inspector icon for the desired operation in the list below the graph.
By default logged information for alerts expires after 1 year (31536000 seconds).
You can change the alert expiration time as follows:
Select Administration > System Services from the Navigator.
Select the AP_Notifier_Service in the summary pane.
