Excluding Third-Party Libraries/Classes from IntelliTrace Monitoring

You can configure IntelliTrace to ignore third-party libraries altogether by adding the package names of the third-party code to the trace-exclusions.txt file in the Applicare home directory. In most cases, you are not interested in the internal working of these third party libraries and excluding them from tracing will reduce the overhead significantly. 

Open the trace-exclusions.txt file in a text editor and you can see that we have already added most of the common libraries such as the Spring framework and Apache Commons in this file. So if you see some third-party classes/methods in you IntelliTrace window that you are not concerned about, you should add the base package name of that library to trace-exclusions.txt in a new line. 

For example, to disable tracing all classes in org.apache and its sub packages, you should add org.apache to trace-exclusions.txt.

Remember to copy the modified file to all agent Applicare directories on other machines. You will have to restart application servers for the changes to take effect. 

Now you can use the modified file in the production Applicare installation to get the best performance while IntelliTrace is enabled. Furthermore, you can send the packages you want excluded to Arcturus so they will be included in the trace-exclusions.txt file by default in future versions.




Dotnet Agent:

For dotnet agent trace-exclusions.txt will exist in the path <DOTNET_AGENT_INSTALLED_DIRECTORY>\Profiler
