To identify if automatic remediation actions have been taken for a health rule violation in AppDynamics, a Performance Analyst should expand the " Description " field of the health rule violation event. This section will provide details on the actions executed as part of the automatic remediation process. These details help analysts understand the steps taken by the system to mitigate the issue without manual intervention.

With Business Transaction Lock Down enabled, AppDynamics prevents automatically discovered traffic from registering additional Business Transactions. Newly observed requests that do not match an existing registered transaction are generally aggregated under the tier’s All Other Traffic transaction, protecting the Controller from uncontrolled Business Transaction growth.

To monitor the new web service as an explicitly named, unique Business Transaction, the Performance Analyst should create a Custom Transaction Match Rule. The rule can identify the service by its Web Service Name and Operation Name, providing deterministic matching and naming independently of automatic transaction discovery. Custom rules are the appropriate mechanism for intentionally introducing important transactions while maintaining lockdown governance.

Changing the automatic discovery rule does not overcome the purpose of lockdown because new automatically discovered transactions remain restricted. Live Preview assists with validating detection-rule behavior but is not the persistent configuration that defines the transaction. All Other Traffic provides aggregated visibility into unregistered traffic; it does not replace a precise custom detection rule.

AppDynamics supports scheduled delivery of Application Health, Controller Audit, and Custom Dashboard reports.

An Application Health report summarizes the operational condition of monitored applications over a selected reporting period. It can include health-rule violations, Business Transaction performance, errors, response-time behavior, and application availability, making it suitable for recurring operational reviews.

A Controller Audit report provides a record of administrative and configuration activity performed in the Controller. It is useful for governance, security review, compliance verification, and tracking changes made by users or administrators.

A Custom Dashboard report captures the widgets and visualizations configured on a selected custom dashboard. It can be generated periodically and emailed to stakeholders who need recurring application, infrastructure, or business-performance summaries without manually opening the Controller.

Ad Hoc Data describes manually selected or temporary analysis rather than a standard schedulable report type. Error Trends may appear as a dashboard visualization or metric analysis, but it is not a distinct scheduled-report category. Tier List is an application inventory view rather than a report designed for periodic email delivery.

The Business Transaction Discovery feature in AppDynamics allows users to identify new and potential business transactions directly within the Business Transaction Dashboard. This feature aids in the continuous monitoring and adaptation of the application ' s transaction tracking to changing business needs, ensuring comprehensive visibility. Users can also preview these identified transactions, assessing their relevance and impact on the application ' s performance before deciding to monitor them as official business transactions.

When configuring Automatic Cleanup of stale Business Transactions, the " minutes since creation " option is often paired with the " Number of Calls " metric. This setting ensures that business transactions that have not been called within a certain timeframe and have had a negligible number of calls are automatically cleaned up, helping to maintain an organized and relevant set of business transactions in the monitoring system.

By default, AppDynamics allows a maximum of 200 registered Business Transactions per application and 50 Business Transactions per node.

The application-level limit controls the total number of unique Business Transactions that can be registered across all tiers and nodes belonging to the application. The node-level limit restricts how many transactions a single Application Agent can independently discover and register. These safeguards prevent uncontrolled Business Transaction growth, excessive metric creation, and unnecessary Controller resource consumption.

When either limit is reached, newly discovered requests are not registered as individual Business Transactions. Instead, they are typically grouped into an All Other Traffic category for the affected tier or entry-point type. Important transactions can still be prioritized by creating Custom Match Rules, excluding low-value traffic, refining transaction naming, or adjusting registration limits where operationally justified.

The application limit is not 100 or 300 by default, and the node limit is not 75 or 200.

The " Method Invocation Data Collector " is specifically designed to capture code-level data such as method arguments, variables, and return values. This type of data collector enables deep visibility into the execution of methods within transactions, providing valuable insights into the application ' s behavior and performance. This detailed level of monitoring is essential for diagnosing complex issues and understanding the inner workings of business transactions.
