jms_ta app and Python vs Python3

rajanala — Tue, 29 Sep 2020 20:19:19 GMT

I have the following setup:-
Splunk Universal Forwarder 6.1.6
OS - AIX
jms_ta - 1.3.8
python3
Java 1.7.0

When we run the jms..py --scheme command, we see this

./splunk cmd /opt/bin/python3 ../etc/apps/jms_ta/bin/jms.py --scheme
Traceback (most recent call last):
File "../etc/apps/jms_ta/bin/jms.py", line 122, in
do_scheme()
File "../etc/apps/jms_ta/bin/jms.py", line 52, in do_scheme
run_java()
File "../etc/apps/jms_ta/bin/jms.py", line 71, in run_java
if (not os.environ.has_key('JAVA_HOME')):

AttributeError: '_Environ' object has no attribute 'has_key'

When we restart splunk service we see this:

ERROR ModularInputs - Unable to initialize modular input "jms" defined inside the app "jms_ta": Introspecting scheme=jms: Unable to run "python /opt/splunkforwarder/etc/apps/jms_ta/bin/jms.py --scheme": child failed to start: No such file or directory

JAVA_HOME
SPLUNK_HOME
and CLASSPATH are all set

Any thoughts ??

You should use python 2.7

Thank you for the information.

We are migrating the app to new AIX servers that can run python3 only.
Is there any version of jms_ta compatible with python3 ?
Appreciate any recommendations you might have.

Splunk runs python 2.7 , try pointing to Splunk's shipped python 2.7 runtime.

It's an universal forwarder which does not ship python 😉 But they could install a full Splunk instance https://www.splunk.com/page/previous_releases#ppcaix and have it run the input and forward the results .... if that is possible on this server ¯\_(ツ)_/¯

Heavy Forwarder implied.
