Filtering wmi events on a heavy forwarder.

[aaronzabell]

I have a bunch of light forwarders sending data to a central heavy forwarder which sends the data to the main indexer.

This is my props.conf and transforms.conf located on the central heavy forwarder. The light forwarders and main indexer do not have a props.conf or transforms.conf. Is this correct and/or what am I doing wrong and is there a more efficient way to do this? Thanks.

props.conf (located %SPLUNK_HOME\etc\system\local\props.conf)

[wmi]
TRANSFORMS-wmi=wminull

transforms.conf (located %SPLUNK_HOME\etc\system\local\transforms.conf)

[wminull]
REGEX=(?m)^Process_Name="C:\\Winpds\\Prismexe\\netman.exe"
DEST_KEY=queue
FORMAT=nullQueue

[wminull]
REGEX=(?m)^Process_Name="C:\\Program*\\Symantec\\Symantec*Endpoint*Protection\\Rtvscan.exe"
DEST_KEY=queue
FORMAT=nullQueue

I think i found it. There is a "." in the REGEX. I needed to put a backslash "\" before the "." So the lines should have been:

REGEX=(?m)^Process_Name="C:\\Winpds\\Prismexe\\netman\.exe"

REGEX=(?m)^Process_Name="C:\\Program*\\Symantec\\Symantec Endpoint Protection\\Rtvscan\.exe"

Did I mention that I'm new to this whole REGEX thing?

I was completely off!

Process_Name can't be used (unless I want to get really hard core in editing other conf files)

Here is the working config:

props.conf

[WinEventLog:Security]
TRANSFORMS-null = setnull

transforms.conf

[setnull]
REGEX=(?msi)^EventCode=(520.*netman\.exe|4656.*rtvscan\.exe)
DEST_KEY=queue
FORMAT=nullQueue

I even used the msi option.

bump! Help? Anyone?

[aaronzabell]

Never mind. It still doesn't work!

Yes, this is right. Please see: http://www.splunk.com/wiki/Where_do_I_configure_my_Splunk_settings%3F for more about where to configure parsing settings.

I don't think my syntax is correct though. These events are still being forwarded to the central indexer.
