Web_service.log is empty after upgrading from Splunk version 7.3 to 8.0.
I have just upgraded my Splunk deployment server from 7.3 to 8.0 and after upgrading the web UI will not come up. I was trying to troubleshoot and was looking at the web_service.log but for some reason it is empty (0 bytes). I cannot figure out why it is not getting any logs or why the UI drops after the upgrade. Any suggestions would be greatly appreciated.

Error messages in Splunkd can help. Also, please check if the certificate that you've specified in web.conf is still valid or not, and the correct path to the certificate is mentioned over there.

the only thing in ./local/web.conf is
[settings]
startwebserver = 1

this is a test DS that I am trying to upgrade before hitting prod.

Hello @dolj
check splunkd.log for any WARNs or ERRORs directly after the restart

checked the splunkd.log while restarting and there were no WARN or ERROR messages only INFO. When you tail the splunkd.log there are not entries written while starting, stopping, or restarting.

@dolj
no log entries at all during restart - that's unusual. Does splunk process running?
ps aux | grep -i splunk

not sure why but it wasn't working and it now is.
I found this log related to the web UI
