Instrumentation for the Mule 4.x framework.
The original releases of the Mule 4.x instrumentation used the New Relic Java Agent Asynchronous framework to tie the transaction together. But in some Mule applications it was resulting in some of the asynchronous tokens not being expired and some async segments not being ended. Because these items are stored in static caches it could consume large amounts of memory and cause problems. In Version 3.0 we started using distributed tracing headers to tie things together. This results in more transactions being reported but everything gets tied together in the Distributed Tracing view and it does not cause memory issues. If the desire is to have one conhesive transaction then use Release V2.0 provided that memory is not being consumed. If the distributed tracing view is acceptable then use Release V3.0
To install:
- Download the latest release jar files.
- In the New Relic Java directory (the one containing newrelic.jar), create a directory named extensions if it does not already exist.
- Copy the downloaded jars into the extensions directory.
- Restart the application.
Once installed, the instrumentation will track transactions through the various Mule components.
Note that the jar necessary for building the Mule-Agent extension are no longer available in Maven. As a result, the extension has been removed from the build process. It can be built if you have access to either AnypointStudio or a Mule Server. Follow the instructions here to build: https://github.com/newrelic-experimental/newrelic-java-mule-4/blob/main/Mule-Agent-Build.md
Note that the a jar necessary for building the Mule-Batch-ee extension are no longer available in Maven. As a result, the extension has been removed from the build process. It can be built if you have access to either AnypointStudio or a Mule Server. Follow the instructions here to build: https://github.com/newrelic-experimental/newrelic-java-mule-4/blob/main/Mule-Batch-Build.md
Building the extension requires that Gradle is installed. To build the extension jars from source, follow these steps:
To build a single extension with name extension, do the following:
- Set an environment variable NEW_RELIC_EXTENSIONS_DIR and set its value to the directory where you want the jar file built.
- Run the command: ./gradlew extension:clean extension:install
To build all extensions, do the following:
- Set an environment variable NEW_RELIC_EXTENSIONS_DIR and set its value to the directory where you want the jar file built.
- Run the command: ./gradlew clean install
