Hello.

I would like sort the data from Windows Security log, but some reason still passed to all the data in Splunk server.

In directory /splunk/etc/system/local/ I have created two files:

  • props.conf

    [WMI:WinEventLog:Security]
    TRANSFORMS-wmi=wminull

  • transforms.conf

    [wminull]
    REGEX=(?m)^EventCode=(528|529|538|540|602|608|609|612|624|628|629|630|631|632|633|634|635|636|637|638|639|642|645|647|668)
    DEST_KEY=queue
    FORMAT=nullQueue

But still in addition EventCode from transforms.conf in Splunk i can see another EventCode.

Maybe someone did a similar sort and can share their code examples or point out my mistakes.

Thanks!

Hello,
Your question is itself the answer :). Universal forwarder will not filter your data through props/transforms.conf. It should be placed on the indexer. in Splunk 6 there are options to specify which one actually you want to forward but you need to filter the

if you really need to filter from forwarder use a heavy forwarder. You will several examples of it how to do in splunkbase.

Thanks
