Is there any problem with DB connect add-on 3.1.3 version ?

[Hemnaath]

Hi, I am getting the following message after installing the db connect add-on 3.1.3 version. We wanted to test the SCCM app, and which requires db connect add-on to configure the inputs. We are using Splunk Trial version 6.6.1

Error details:

Unable to initialize modular input "server" defined inside the app "splunk_app_db_connect": Introspecting scheme=server: script running failed (exited with code 1).

Kindly guide me how to fix this issue.

To start troubleshooting the issue, you can run below command on Splunk server on which DB Connect is installed.

$SPLUNK_HOME/splunk/bin/splunk cmd splunkd print-modinput-config --debug server

In my lab environment I don't have java installed so it is throwing almost same error but with error code 127 and when I ran above command I found the actual issue that java is not installed

Thank you for that answer. Here is what I get if I run the suggested command..

It looks like Java mismatch, have you installed JRE 8 from Oracle ? Please look at prerequisites for DB connect https://docs.splunk.com/Documentation/DBX/3.1.3/DeployDBX/Prerequisites#Java_Runtime_Environment_.28...

[velsankar]

Thank you. Yes, I have installed the right JRE and get the following results if I run the debug command.

But still the splunk db connect fails to load and continue to show the loading symbol forever. The browser console has the following error:
Uncaught (in promise) TypeError: Cannot read property 'Symbol(Symbol.iterator)' of undefined
at ftr.js:1

The only difference is that the recursive taskserver start failure message on the browser console is not there anymore after the correct JRE installation. So I guess the taskserver is running now.

Can anyone let me know how to fix this error message, I am unable to access the db connect application.

Hi

Did you find a solution for this? I am facing the same error

[Hemnaath]

Hi Velsankar, no I did not find any solution for this error, so dropped configuring it.
