Monitor Business Transactions
AppDynamics can auto-discover business transactions from common entry points into your JVM such as servlets, struts actions, spring MVC, web services calls and even custom POJO entry points. From this context you can see how business transactions execute through various Java components like SOAP, EJB, JDBC, JMS, and CICS, allowing you to monitor JVMs from a high level.
Real-Time Alerting for the JVM
AppDynamics also provides dynamic SLA base-lining and pro-active alerting so that performance issues can be notified as they surface, giving application and production support teams an early warning before end user experience and service levels start to breach.
OutOfMemoryExceptions and Memory Leaks
AppDynamics also provides the user with visibility of heap usage, garbage collection and utilization of key memory pools over-time. AppDynamics can also track and monitor memory leaks automatically inside the JVM with minimal user analysis allowing root cause to be found in minutes instead of days or weeks.
Detect Thrown Exceptions
AppDynamics can collect and report all application run-time exceptions that are thrown inside the JVM server. This provide users with visibility of stack traces that are thrown when business transactions and user requests timeout or fail.
Monitor SQL and NoSQL Queries
AppDynamics can also detect both slow SQL statements and NoSQL query latency with full visibility into SQL text and NOSQL queries like Cassandra Thrift and MongoDB BSON. Like JMX monitoring tools, you can also use AppDynamics to monitor the size of the database connection pool and other JMX metrics to better understand how your application interacts with the database.
More about What You Can Do with AppDynamics JVM Monitoring
While there are many free JVM monitoring tools, many of them are difficult to use and incur too much overhead to be suitable for a production environment. With AppDynamics you can monitor JVM health and performance in a live production environment without having to worry about affecting end user experience.
