monitoring with Instana

Daniel Kostyal

Hello,

We need to monitor the Atlassian software suite (Jira, BitBucket and Confluence ), located on-prem, with Instana.

The issue we have is that Instana is not able to attach to the JVM to monitor it. We investigated the cause and we found that there are two prerequisites modules needed on java of the Atlassian products. Those are : java.instrument and jdk.attach.

The java.instrument is already configured as we listed the modules for all the java, but jdk.attach is missing.

Can someone guide us how can we add the required module to the java that is used by Jira,Confluence and BitBucket?

The versions that are installed are Jira v8.20.2, Atlassian Bitbucket v7.19.3 and Confluence v7.15.0.

The official Instana docs: https://www.ibm.com/docs/en/obi/current?topic=technologies-monitoring-java-virtual-machine#java-runtimes-9-or-higher

Many thanks!

Daniel

Did you find an anwer to this? I was thinking about using Instana with our Atlassian products as well to test if it helps us.

That might be possible to repack jdk.attach into exisiting jre.

I am trying to test:

1) replace $JAVA_HOME/lib/modules , source from original openjdk or oracle
2) add jdk.attach.jmod under $JAVA_HOME/jmod. (Legal is an optional).
3) add libattach.so under $JAVA_HOME/lib

Probably failed. It seems need to rebuild the JRE from adoptium java source. However, Atlassian also provided a guide to replace common JRE : https://confluence.atlassian.com/doc/change-the-java-vendor-or-version-confluence-uses-962342397.html

I found the proper way to solve this and have verified on my local test environment. Please replaced bundle JRE by OpenJDK (not JRE). Download specific version which is compatible with Confluence version : https://github.com/adoptium/temurin11-binaries/releases

Instana can do.
