I am facing the same issue
" Unable to initialize modular input "testfile" defined inside the app "test1": Introspecting scheme=testfile: script running failed (exited with code 1)."
The modular input is developed using java . any hints on coming out of this problem is greatly appreciated .
Have a look in the splunkd logs for more error details :
You can use a search command like :
index=_internal error ExecProcessor source=*splunkd*
Here are some tips here for manually debugging a mod input :
http://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/ModInputsDevTools
So you can manually execute the mod input(fill in the relevant values($STANZA_NAME ,$LTA_SCRIPT_NAME ) for your "ltatest" mod input) :
splunk cmd splunkd print-modinput-config LTA $STANZA_NAME | splunk cmd python $SPLUNK_HOME/etc/apps/LTATest/bin/$LTA_SCRIPT_NAME
What if it doesn't show any error?
