Top Free Tools for Monitoring Java Applications This blog post is about popular tools you can use to monitor Java application performance. To optimize Java application performance, it is important to identify times when the application becomes slow due to a call to a third-party service. Calls to external services: Java applications may involve HTTP/web services calls to external services.When such an issue happens, IT administrators will need to determine whether the slowness is due to a query that is not properly framed or whether the slowness is due to a bottleneck on the database server. When queries issued by the Java application take time, users will see slowness. Data access: Java applications often rely on database servers for data access.Deadlocks, thread leaks, and high CPU threads can all slow down the Java application. Multi-threading: While multithreading enables parallelism and faster processing, it can also result in a number of performance anomalies.At the same time, garbage collection has a cost: too many collections will take its toll on performance. Garbage collection: Java provides automatic memory management, therefore, the developer does not have to manually dispose obsolete objects.Java applications pose unique challenges: Java Application Development Lifecycle Challenges with Monitoring Java Applications Performance considerations when assessed during the development phase itself can significantly reduce the time from delivery to stability of applications in production.

Many a times, such situations warrant a complete restructuring of the application code, causing significant impact to new rollouts and current users.

When these applications are deployed in production, scalability and performance issues surface and application developers then have to worry about performance. Software developers are often only concerned about the functionality of their applications. Monitoring is Not a Focus of Java Developers
