Download NXLog Community Edition from here:

and install it. Make of note of where the nxlog.conf file is.

Edit the nxlog.conf file and add the following to the end:

<Output syslog_tls>
    Module      om_ssl
    Host        212.219.243.132
    Port        6514
    CAFile      c:/Program Files (x86)/nxlog/data/cacert.pem
    CertFile    c:/Program Files (x86)/nxlog/data/clientreq.pem
    CertKeyFile c:/Program Files (x86)/nxlog/data/clientkey.pem
    AllowUntrusted 1
    OutputType	Syslog_TLS
    Exec        to_syslog_ietf();
</Output>

<Output syslog_tcp>
    Module      om_tcp
    Host        212.219.243.132
    Port        601
    OutputType  Syslog_TLS
    Exec        to_syslog_ietf();
</Output>

<Input eventlog>
    Module  im_msvistalog
    <QueryXML>
      <QueryList>
        <Query Id="0" Path="System">
          <Select Path="System">*[System[Provider[@Name='NPS']]]</Select>
          <Select Path="Security">*[System[Provider[@Name='Microsoft-Windows-Security-Auditing'] and Task = 12552]]</Select>
        </Query>
      </QueryList>
    </QueryXML>
</Input>

<Route 1>
    Path        eventlog => syslog_tcp
</Route>

Save the file and restart the service.

The first stanza, syslog_tls, is just there for information. It's not actually used in this configuration. At a later date we'll be looking at encryption but there's a PKI to build.

This is all fairly self-explanatory. OutputType Syslog_TLS is needed to enforce the RFC5424 standards along with Exec to_syslog_ietf(). Not sure why both are needed but they really are.

In the Eventlog config the QueryXML is extracted from Windows Event Log (Event Viewer → Custom View →. Server Roles. Right click on Network Policy…. Choose Properties, Edit Filter, XML and copy the XML into the NXLog config).

Some customisation might be needed to filter only for traffic between sites, rather than traffic to/from Jisc NRPS.
