Overview

This article addresses the issue where device name resolution is enabled in Kiwi Syslog Server NG, but the Hostname column still shows the device’s IP address rather than the hostname.

Product section

Kiwi Syslog Server

Cause

The issue occurs when the file DisplayBuffer.json in the installation directory is missing or corrupted. The default installation path is:
C:\Program Files (x86)\SolarWinds\Kiwi Syslog Server NG

Resolution

  1. Verify Hostname Resolution Setting
    • Open Kiwi Syslog Server NG.
    • Navigate to Setup > Settings > DNS.
    • Ensure the checkbox "Resolve the IP address of sending device" is enabled.
  2. Check Local DNS Cache
    • On the host machine, open a Command Prompt.
    • Run the command:
      ipconfig /displaydns
    • Confirm that DNS entries exist for the affected devices.

  1. Confirm Presence of DisplayBuffer.json

    • Navigate to the Kiwi Syslog Server NG installation directory:
      C:\Program Files (x86)\SolarWinds\Kiwi Syslog Server NG
    • Verify that the file DisplayBuffer.json exists.
  2. Repair Installation if Needed
    • If DisplayBuffer.json is missing or corrupted, re-run the Kiwi Syslog Server NG installer over the existing installation to perform a repair.

IMPORTANT NOTE

The installer must run using Local Administrator, not domain permissions. The user either must be a member of the Local Administrators group on the host or a member of an AD group that is a member of the Local Administrators group.
