Use SysName for Hostname

ThirdEye retrieves the hostname from your DNS server and displays it in the Editor’s [Devices] tab. sysName serves as the primary host identifier for syslog messages when DNS resolution is disabled. When configured to use SysName for hostname identification, syslog handling changes:

• Host Identification: SNMP sysName from device inventory are used instead of DNS reverse lookup. And valid SNMP credentials are required for accurate device correlation.
• Syslog Rules: Filtering rules based on hostname now reference sysName values.
• Operations: Consistent sysName values are required across devices. Audit logs show sysName instead of DNS-resolved names.

To use the host name (sysName) on the device, use the following settings.
