NetWitness 11.0. added the capability to view a small sampling of recent logs for specific devices through detail tabs of the Discovery View. By default, Log Decoders prior to 11.0 do not have the necessary configuration to enable this feature, but a few minor changes can make it available.

To enable logs preview for a pre-11.0 Log Decoder, follow these steps on the Log Decoder:

  1. Go to AdminIcon_25x22.png (Admin) > Services > select a Log Decoder, then select ic-actns2.png > View > Config.
  2. Click the Files tab and select index-logdecoder-custom.xml from the drop-down menu.
  3. Add the following three lines at the end of the file (before the closing language tag):

    <key description="Device IP" level="IndexValues" name="device.ip" format="IPv4" valueMax="100000" defaultAction="Open"/>
    <key description="Device IPv6" level="IndexValues" name="device.ipv6" format="IPv6" valueMax="100000" defaultAction="Open"/>
    <key description="Device Host" level="IndexValues" name="" format="Text" valueMax="100000" defaultAction="Open"/>

  4. Click Apply.
  5. Restart the Log Decoder service as follows.

    Select Log Decoder service > Explore > decoder > Properties > reset. You select reset from a drop down menu.

Click Send after you select reset.

This is an example of the index-logdecoder-custom.xml file.
