description: ECS Fields.
fields:
- name: '@timestamp'
level: core
required: true
type: date
description: 'Date/time when the event originated.
This is the date/time extracted from the event, typically representing when
the event was generated by the source.
If the event source has no original timestamp, this value is typically populated
by the first time the event was received by the pipeline.
Required field for all events.'
example: '2016-05-23T08:05:34.853Z'
- name: labels
level: core
type: object
object_type: keyword
description: 'Custom key/value pairs.
Can be used to add meta information to events. Should not contain nested objects.
All values are stored as keyword.
Example: `docker` and `k8s` labels.'
example:
application: foo-bar
env: production
- name: message
level: core
type: text
description: 'For log events the message field contains the log message, optimized
for viewing in a log viewer.
For structured logs without an original message field, other fields can be concatenated
to form a human-readable summary of the event.
If multiple messages exist, they can be combined into one message.'
example: Hello World
- name: tags
level: core
type: keyword
ignore_above: 1024
description: List of keywords used to tag each event.
example: '["production", "env2"]'
- name: agent
title: Agent
group: 2
description: 'The agent fields contain the data about the software entity, if
any, that collects, detects, or observes events on a host, or takes measurements
on a host.
Examples include Beats. Agents may also run on observers. ECS agent.* fields
shall be populated with details of the agent running on the host or observer
where the event happened or the measurement was taken.'
footnote: 'Examples: In the case of Beats for logs, the agent.name is filebeat.
For APM, it is the agent running in the app/service. The agent information does
not change if data is sent through queuing systems like Kafka, Redis, or processing
systems such as Logstash or APM Server.'
type: group
fields:
- name: ephemeral_id
level: extended
type: keyword
ignore_above: 1024
description: 'Ephemeral identifier of this agent (if one exists).
This id normally changes across restarts, but `agent.id` does not.'
example: 8a4f500f
- name: id
level: core
type: keyword
ignore_above: 1024
description: 'Unique identifier of this agent (if one exists).
Example: For Beats this would be beat.id.'
example: 8a4f500d
- name: name
level: core
type: keyword
ignore_above: 1024
description: 'Custom name of the agent.
This is a name that can be given to an agent. This can be helpful if for example
two Filebeat instances are running on the same host but a human readable separation
is needed on which Filebeat instance data is coming from.
If no name is given, the name is often left empty.'
example: foo
- name: type
level: core
type: keyword
ignore_above: 1024
description: 'Type of the agent.
The agent type stays always the same and should be given by the agent used.
In case of Filebeat the agent would always be Filebeat also if two Filebeat
instances are run on the same machine.'
example: filebeat
- name: version
level: core

title: Autonomous System
group: 2

(IP) routing prefixes under the control of one or more network operators on
behalf of a single administrative entity or domain that presents a common, clearly
defined routing policy to the internet.

description: Organization name.
example: Google LLC
- name: client
title: Client
group: 2
description: 'A client is defined as the initiator of a network connection for
events regarding sessions, connections, or bidirectional flow records.
For TCP events, the client is the initiator of the TCP connection that sends
the SYN packet(s). For other protocols, the client is generally the initiator
or requestor in the network transaction. Some systems use the term "originator"
to refer the client in TCP connections. The client fields describe details about
the system acting as the client in the network event. Client fields are usually
populated in conjunction with server fields. Client fields are generally not
populated for packet-level events.
Client / server representations can add semantic context to an exchange, which
is helpful to visualize the data in certain situations. If your context falls
in that category, you should still ensure that source and destination are filled
appropriately.'
type: group
fields:
- name: address
level: extended
type: keyword
ignore_above: 1024
description: 'Some event client 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.'
