Business Transaction metrics are the key performance indicators that measure the health and
performance of your applications. They include metrics such as average response time, calls per
minute, errors per minute, and so on. You can use various types of performance degradation analysis
to identify and troubleshoot the root causes of performance issues using Business Transaction
metrics.
According to the Troubleshoot Business Transactions - AppDynamics, the following types of
performance degradation analysis are used with Business Transaction metrics:
Correlation Analysis: This type of analysis helps you to find the correlation between different metrics
and events that may affect the performance of your Business Transactions. For example, you can use
the correlation analysis to see how the response time of a Business Transaction is related to the CPU
utilization of a node, or how the error rate of a Business Transaction is related to the number of slow
database calls.
Remote Services Analysis: This type of analysis helps you to understand how the performance of your
Business Transactions is impacted by the calls to remote services, such as databases, web services,
message queues, and so on. For example, you can use the remote services analysis to see the
response time, call count, error count, and wait time of each remote service call, and drill down to
the details of each call.
Compare Releases: This type of analysis helps you to compare the performance of your Business
Transactions across different releases of your application. For example, you can use the compare
releases analysis to see how the response time, error rate, and throughput of your Business
Transactions have changed after a new deployment, and identify any performance regressions or
improvements.
Therefore, A (Correlation Analysis), B (Remote Services Analysis), and E (Compare Releases) are
three types of performance degradation analysis that are used with Business Transaction
metrics. Reference:
