Host discovery: Host
Enable IP address matching for Host search: In certain environments, where hosts or VMs are frequently provisioned and/or decommissioned causing IP addresses to be re-used, these duplicate IP addresses can result in multiple aliases for a single host. Use this parameter to activate/deactivate IP address matching. When the parameter is disabled, a collected host with an IP address that matches a host in the database, but that has a different host name, will result in the creation of a new host in the database. By default, this value is disabled and its value is preserved even after upgrades.
You can enable this parameter only when you are certain that the IP addresses will never get reassigned and reused by different hosts.
The options to enable base name (Enable base name matching for Host search) and short name (Enable short name matching for Host search) matching for host search provide administrators with better control to find hosts in IT Analytics. The short name refers to the shortest possible matching name when the FQDN is parsed into its constituent tokens. The base name matches the left-most token in the FQDN of a host, also known as the host name, when it is parsed into its constituent tokens.
