WinEventLog filters failing :Windows 2003 and splunk 6 SPL-78726

[yannK]

After upgrading my Windows servers 2003 to Splunk 6. I discovered that all my nullQueues filter stopped working, and I indexed mode data than before.

I checked, and the reason is that the sourcetype name for the WinEventLog has a different case for the first letter of the channel :

• WinEventLog:Security
• WinEventLog:System
• WinEventLog:Application
• WinEventLog:Capitalized-channel-name

became under Splunk 6 for Win 2003 only

• WinEventLog:security
• WinEventLog:system
• WinEventLog:application
• WinEventLog:smallcaps-channel-name

---

FYI my filter on the indexers and heavy forwarders were :

• in props.conf

[WinEventLog:Security]
TRANSFORMS-nullqueuefilter=MyNullQueueFilter


• in transforms.conf

[MyNullQueueFilter]
REGEX = (Windows Update)
DEST_KEY = queue
FORMAT = nullQueue


[yannK · Accepted solution]

This is a known bug SPL-78726, the fix is not yet released in Splunk 6.0 or 6.0.1

For the search, the sourcetypes are case insensitive, so you will find the events.
But for the props.conf matching the regex and stanza are case sensitive, so they may not apply anymore.

Workaround :

• change your props.conf to match all your formats

`
[WinEventLog:Security]
TRANSFORMS-nullqueuefilter=MyNullQueueFilter

[WinEventLog:security]
TRANSFORMS-nullqueuefilter=MyNullQueueFilter
`

• force the sourcetype name in the inputs.conf


[WinEventLog://Security]
sourcetype=WinEventLog:Security

change on Indexers and Heavy forwarders

[aberdamy]

Thank you for your response however I'm not sure what you're saying here could you please clarify?

[yannK]

the indextime filters only applies on the instances parsing the events : Indexers and Heavy forwarders (if any)

If you had custom props.conf that were working, change they were they already exist.

[aberdamy]

So do we change the props.conf on the forwarder or indexer? Also, are these two separate workarounds that will solve the issue or are they to be used together?

[yannK]

As you wish,
- system/local will always win, so this is a very definitive place to change
- While an app can be deployed easily to all instances using a deployment server

[aberdamy]

which inputs.conf should I change this in the apps or the system/local directory?
