Source Fields
editSource Fields
editSource fields describe details about the source of a packet/event.
Source fields are usually populated in conjunction with destination fields.
Source Field Details
editField | Description | Level |
---|---|---|
source.address |
Some event source 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 Then it should be duplicated to type: keyword |
extended |
source.bytes |
Bytes sent from the source to the destination. type: long example: |
core |
source.domain |
Source domain. type: keyword |
core |
source.ip |
IP address of the source (IPv4 or IPv6). type: ip |
core |
source.mac |
MAC address of the source. type: keyword |
core |
source.nat.ip |
Translated ip of source based NAT sessions (e.g. internal client to internet) Typically connections traversing load balancers, firewalls, or routers. type: ip |
extended |
source.nat.port |
Translated port of source based NAT sessions. (e.g. internal client to internet) Typically used with load balancers, firewalls, or routers. type: long |
extended |
source.packets |
Packets sent from the source to the destination. type: long example: |
core |
source.port |
Port of the source. type: long |
core |
source.registered_domain |
The highest registered source 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: |
extended |
source.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: |
extended |
