Release Notes

Business transaction health refers to the extent to which a business transaction is experiencing critical and warning health rule violations.

Use health rules, notification actions and policies to alert staff of business transaction performance problems.

Default Health Rules for Business Transactions

AppDynamics provides the following default health rules for business transaction performance:

  • Business Transaction response time is much higher than normal
    This rule defines a critical condition as the combination of an average response time greater than the default baseline by 3 standard deviations and a load greater than 50 calls per minute.
    This rule defines a warning condition as the combination of an average response time greater than the default baseline by 2 standard deviations and a load greater than 100 calls per minute.
  • Business Transaction error rate is much higher than normal
    This rule defines a critical condition as the combination of an error rate greater than the default baseline by 3 standard deviations and an error rate greater than 10 errors per minute and a load greater than 50 calls per minute.
    This rule defines a warning condition as the combination of an error rate greater than the default baseline by 2 standard deviations and an error rate greater than 5 errors per minute and a load greater than 50 calls per minute.

You can use these health rules as they are or you can modify them.

For information on how AppDynamics determines normal performance, see Behavior Learning and Anomaly Detection and Configure Baselines.
For information about modifying health rules see Health Rules and Configure Health Rules.

Alerting with Notification Actions

You can create notification actions to set up email and SMS addresses to receive notifications when the health rules are violated. See Notification Actions.

You can also create email digests that are sent on a predefined schedule to email recipients summaries of these (and other) health rule violations. See Email Digests.

Alerts in email notifications and digests provide a deep link to help the recipient start analyzing the root cause of the problem.

Creating Policies to Match Health Rule Violations with Alerts

Create one or more polices to assign a notification action to a specific health rule violation. You can optionally create different policies for warning and critical health rule violations. See Policies and Configure Policies.

If you want simply to send an email notification to a single email address whenever any health rule violation is started, you can use the Alerting Wizard.
