Getting Data In

Why am I getting error "Received event for unconfigured/disabled/deleted index="wineventlog"" when the index does exist?

Explorer

Hello,

I am trying to log the Sysmon/Operational Windows event logs via the Sysmon TA app:

[WinEventLog://Microsoft-Windows-Sysmon/Operational]
disabled = false
renderXml = true
index=wineventlog

But when I push the app to the Universal Forwarders on my Windows boxes, I am receiving the error:

Received event for unconfigured/disabled/deleted index="wineventlog" with source="source::WinEventLog:Microsoft-Windows-Sysmon/Operational" host="host::XX" sourcetype="sourcetype::XmlWinEventLog:Microsoft-Windows-Sysmon/Operational". So far received events from 1 missing index(es).

The challenge is that the index does exist and is enabled:
alt text

It was originally created by the Windows TA app, so I deleted it, recreated it, put it in indexes.conf, but nothing. I cannot see the issue.

Any help would be appreciated.

So I figured out what the issue is. I set the index in inputs.conf which made the hard-coded checksum fail and refuse to install

The universal forwarder splunkd.log has the error:

To fix it I removed the checksum in the app.conf file.

Thanks for your help.

Why that would cause the message you saw on the indexer I am not sure, but I am glad you figured it out!

Yeah, that part is weird because it seems to me like it shouldn't be attempting to send any logs to the indexer. Weird.

If you haven't already done so, I would try restarting your indexers to ensure they are initializing the indexes.conf config updates.

Can you run sudo ./splunk cmd btool indexes list --debug | grep -A 10 "\[wineventlog" on your indexer and share the output, please?

Hmmm, that is weird. When you run a search on the indexer using index=wineventlog, do you see data? Your screenshot suggests there should be events in it.
The only other thing I can think of is some weird non-printable control character in your inputs.conf.

Yes, security and application event logs are streaming in no problem. I'll try running dos2unix on the inputs.conf file...

I think that is a great idea... Please report back.
