I've configured each input, however I am seeing no data, and no errors in the _internal logs for the heavy forwarder. What additional troubleshooting can I do?
Are you using this add-on - https://splunkbase.splunk.com/app/3534/ ?
If so, have you configured the Azure side to send data to an event hub and set up an Azure application and key vault - https://www.splunk.com/blog/2018/04/20/splunking-microsoft-azure-monitor-data-part-1-azure-setup.htm... ?
FYI, you can use a script to automate the Azure setup -> https://github.com/Microsoft/AzureMonitorAddonForSplunk/tree/master/scripts
I ended up reviewing firewall logs and noticed it's blocking some of the TLS ports. Also, the Python changes required for this Add-on broke the Add-on for JMX Extensions unfortunately. I guess we're going to have to put the Azure Add-on on its own HF.
