  2. In the Connections tab, select either the server or the site, and then click the FTP Logging icon.

Configure NXLog on Windows

To send log data through NXLog to USM Appliance

  1. If not done already, download nxlog.conf, and then place it in the conf directory of your NXLog installation. Depending on which version you use, the directory can be C:\Program Files (x86)\nxlog\conf\ for the 32-bit version or C:\Program Files\nxlog\conf\ for the 64-bit version.

    Note: This step overwrites the default nxlog.conf file. You may want to back up the original copy before placing the one provided by LevelBlue.

  2. Open the nxlog.conf file in a text editor.
  3. Update the root path of your NXLog installation.

    1. Locate the following lines:

      #define ROOT C:\Program Files\nxlog

      #define ROOT C:\Program Files (x86)\nxlog

    2. Uncomment the path that matches the NXLog installation on your Windows machine.
  4. Enter the USM Appliance Sensor IP address.

    1. Locate the following line:

      define OUTPUT_DESTINATION_ADDRESS <USM-Appliance-Sensor-IP>

    2. Replace <USM-Appliance-Sensor-IP> with the IP address of the USM Appliance All-in-One or USM Appliance Sensor that will receive the Windows events.
  5. Uncomment the section between FTP-NXLOG and /FTP-NXLOG.

    Important: Only remove the first # symbol in each line when uncommenting the sections. The remaining # symbol indicates that the line is either a comment or optional.

  6. In addition, uncomment the following lines, above the DHCP-NXLOG section:

    #<Extension json>

    # Module xm_json


  7. Save the file.
  8. Start or restart the NXLog service.
