Trouble installing Splunk_TA_jmx Add-on: Has anyone seen the following error?

[robgora_deloitt]

I have the Splunk_TA_jmx add-on installed on a Heavy Forwarder but am getting the following error:

Introspecting scheme=jmx: script running failed (exited with code 1).
Unable to initialize modular input "jmx" defined inside the app "Splunk_TA_jmx": Introspecting scheme=jmx: script running failed (exited with code 1).
Scheme "jmx" is not initialized.

I ran the following:

sudo -u splunk /opt/splunk/bin/splunk cmd splunkd print-modinput-config jmx |/opt/splunk/bin/splunk cmd /opt/splunk/bin/python /opt/splunk/etc/apps/Splunk_TA_jmx/bin/jmx.py

and this is what I got:

Introspecting scheme=jmx: script running failed (exited with code 1).
Unable to initialize modular input "jmx" defined inside the app "Splunk_TA_jmx": Introspecting scheme=jmx: script running failed (exited with code 1).
Scheme "jmx" is not initialized.

Any thoughts on this?

I found my own issue here. It seems that you have to have Java installed on the Heavy Forwarder for this add-on to work.

Hi,

Have you installed Java Run time ? Please see prerequisite here http://docs.splunk.com/Documentation/AddOns/released/JMX/Hardwareandsoftwarerequirements#Prerequisit...

If JRE is installed then you can run below command to check introspection scheme

/opt/splunk/bin/splunk cmd python /opt/splunk/etc/apps/Splunk_TA_jmx/bin/jmx.py --scheme
