After verifying and refining your business transaction scheme, you can focus on monitoring business transaction performance. The monitoring and troubleshooting tools within the AppDynamics Controller UI provide a business transaction oriented view of performance. For example, transaction snapshots tie together all the code call graphs across the monitored tiers that participated in processing a particular instance of a business transaction.

The business transaction list contains a high level look at the performance of the business application by transaction. You can click on a particular business transaction to access additional information on the business transaction, such as information on slow performing instances of this transaction, errors, and the transaction analysis view.

Performance at a Glance

The transaction scorecard summarizes the performance of a business transaction at the application, tier, or node level within a specified time range. It covers the number and percentage of business transaction instances (calls) that are normal, slow, very slow, stalled, or errors based on the configured thresholds for these criteria.

The call counts in the score cards in different dashboards have different meanings:

Transaction Score View

For a more detailed view of the performance of a transaction over time, navigate to the business transaction dashboard and click the Transaction Score tab. The graph in the tab shows the user experience for the selected business transaction, showing its performance relative to the performance thresholds as a bar chart.

For each time slot, the bar reflects the total calls, while the color segments—green, yellow and so on—indicate the relative number of those calls that were normal, slow, very slow, stall or errors.  

The solid blue line in the graph indicates the average response time for the transaction over time, while the dotted line shows the baseline, if available.
