Considerations if upgrading from version 3.0.2

If you are upgrading from version 3.0.2 or earlier of the Splunk Add-on for JMX, note that the assignment of the host and source fields has changed since the 3.1.0 release as noted in ADDON-5508. These changes may cause existing searches to no longer work. You will need to revise your SPL searches to use the correct host or source if any of your SPL searches depend on host or source.

Migration Guide

The Splunk Add-on for JMX is intended to replace the add-on components of Monitoring of Java Virtual Machines with JMX. Splunk built the Splunk Add-on for JMX as a separate add-on, so you cannot use the update function in your existing installation of the Monitoring of Java Virtual Machines with JMX app to install and use this add-on. The Splunk Add-on for JMX is compatible with the old app's inputs.conf and XML configuration files, so you can manually upgrade and continue to use your old configurations.

Some features of the Monitoring of Java Virtual Machines with JMX app are not available in this add-on.

• Although the element formatter still exists for backwards compatibility, the add-on does not use it. Now the add-on indexes events in JSON format for better field extractions.
• Although the attribute filterImplementationClass still exists in element notification, the attribute is not used in this version.

Migration steps

This add-on does not work with the Monitoring of Java Virtual Machines with JMX app on the same Splunk Enterprise instance, so you must follow these migration steps to upgrade.

If you do not want to keep your old configurations and plan to create new data inputs, you can just remove the Monitoring of Java Virtual Machines with JMX app and install this add-on.

If you want to keep your old configurations, follow these steps.

1. Find the folder where the Monitoring of Java Virtual Machines with JMX app is installed. By default, it is $SPLUNK_HOME/etc/apps/jmx_ta.
2. Back up your XML configuration files in the app folder or its sub-folders.
3. Back up your inputs.conf in the local folder.
4. If you changed your inputs.conf in the default folder, merge your changes into your backup copy of your local/inputs.conf.
5. Backup all the other files in the local folder if you need them.
6. Uninstall the old app, or delete the app folder.
7. Install the Splunk Add-on for Java Management Extensions.
8. Put your backed up copy of your local/inputs.conf into $SPLUNK_HOME/etc/apps/Splunk_TA_jmx/local/.
9. Put your backed up XML configuration files into $SPLUNK_HOME/etc/apps/Splunk_TA_jmx/bin/config/.
10. Check the value of configuration config_file_dir in your local/inputs.conf.
    • If you did not set any value for config_file_dir in the stanza [jmx] in the old app's inputs.conf, the default value is now $SPLUNK_HOME/etc/apps/Splunk_TA_jmx/bin/config/. If you did set it, please change it to $SPLUNK_HOME/etc/apps/Splunk_TA_jmx/bin/config/.
    • Check the value of configuration config_file_dir in all your JMX data inputs in every app using those XML files. Make sure each data input's config_file_dir is set to $SPLUNK_HOME/etc/apps/Splunk_TA_jmx/bin/config/.
11. The default index is now the default index of Splunk Enterprise, instead of jmx. Also, the add-on does not include the index jmx index. If you want to use it, you need to add it manually. You also need to manually set index=jmx in all your JMX data inputs if you were using the old default value and want to continue to use jmx.
