Destination Fields

edit

Destination fields describe details about the destination of a packet/event.

Destination fields are usually populated in conjunction with source fields.

Destination Field Details

edit

Field	Description	Level
destination.address	Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the `.address` field. Then it should be duplicated to `.ip` or `.domain`, depending on which one it is. type: keyword	extended
destination.bytes	Bytes sent from the destination to the source. type: long example: `184`	core
destination.domain	Destination domain. type: keyword	core
destination.ip	IP address of the destination. Can be one or multiple IPv4 or IPv6 addresses. type: ip	core
destination.mac	MAC address of the destination. type: keyword	core
destination.nat.ip	Translated ip of destination based NAT sessions (e.g. internet to private DMZ) Typically used with load balancers, firewalls, or routers. type: ip	extended
destination.nat.port	Port the source session is translated to by NAT Device. Typically used with load balancers, firewalls, or routers. type: long	extended
destination.packets	Packets sent from the destination to the source. type: long example: `12`	core
destination.port	Port of the destination. type: long	core
destination.registered_domain	The highest registered destination domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". type: keyword example: `example.com`	extended
destination.top_level_domain	The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". type: keyword example: `co.uk`	extended
