Nxlog Multiline Input to 1 Syslog Message

  • 772

I am using nxlog to tail a custom log file on one of my Windows servers. Each entry in the text file looks similar to this.

===================================================================================================================
1/14/2014 3:08:48 PM DOMAIN\user1 adding group member...
    Domain: blah
    Group: TestGroup
    Member: CN=Joe Bob,CN=Users,DC=blah,DC=ARG,DC=com
1/14/2014 3:08:48 PM 1 member added.<br>
================================================================================================

I'm trying to send this log to my syslog server and I want to combine these multiple lines to 1 line so I can easily grep/search for specific users or groups. I've read some of the documentation on nxlog's website regarding multiline but haven't found a specific config to put them all in 1 entry with a syslog header.

Thanks, Eric

    Have not tested but I think you need something like this:

    <Extension multi>
    Module  xm_multiline
    HeaderLine  /^================/
    EndLine     /^===============/
</Extension>

<Input in>
    Module      im_file
    File        "input.log"
    InputType   multi
    # Remove the boundary markers
    Exec        if $raw_event =~ s/========[=]+//g {}
    # Make a single line
    Exec        $raw_event = replace($raw_event, "\r\n", " ");
</Input>

<Output>
    Module      om_udp
    Host        1.2.3.4
    Port        514
    Exec        to_syslog_bsd();
</Output>
