App Issues on Splunk Heavy Forwarder

Communicator

I'm trying to get my app input coming in via a heavy forwarder. I've deployed the app to the heavy forwarder and configured the necessary but, I'm seeing these logs in my splunkd.log file in the heavy forwarder.

See splunkd.log for more details.

Anyone have any ideas what's the issue?

Re: App Issues on Splunk Heavy Forwarder

Communicator

I found out what the issue is already.

I added the inputs and the API key and connect ID through my Splunk master web UI, and then I copied the generated configuration files to the deployment-apps folder to be pushed to my heavy forwarder. However, this would not work as the encryption would be different.
Note: The app encrypts the API key and connector ID.

To solve this issue, I removed the deployed app so that the forwarder will not pull the apps from the master, then I enabled the webserver on the heavy forwarder using ./splunk enable webserver, installed the app directly to the heavy forwarder and configured from the heavy forwarder web UI. After that, I disabled the webserver using ./splunk disable webserver to save resources.
