      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.

            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.

            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.

        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 conjuction with server fields.  Client fields are generally not populated for packet-level events.

        The event fields are used for context information about the log or metric event itself. A log is defined as an event containing details of something that happened. Log events must include the time at which the thing happened. Examples of log events include a process starting on a host, a network packet being sent from a source to a destination, or a network connection between a client and a server being initiated or closed. A metric is defined as an event containing one or more numerical or categorical measurements and the time at which the measurement was taken. Examples of metric events include memory pressure measured on a host, or vulnerabilities measured on a scanned host.

            This contains high-level information about the contents of the event. It
            is more generic than `event.action`, in the sense that typically a

            This timestamp is distinct from @timestamp in that @timestamp contains

            as the timestamp in the log line and when the event is read for example
            by Filebeat are not identical. `@timestamp` must contain the timestamp
            extracted from the log line, event.created when the log line is read.
            The same could apply to package capturing where @timestamp contains the
            timestamp extracted from the network package and event.created when the
            event was created.
    
            In case the two timestamps are identical, @timestamp should be used.

        The service fields describe the service for or from which the data was

            Unique identifier of the running service.
    
            This id should uniquely identify this service. This makes it possible
            to correlate logs and metrics for one specific service.
    
            Example: If you are experiencing issues with one redis instance, you
            can filter on that id to see metrics and logs for that single instance.

            Name of the service data is collected from.
    
            The name of the service is normally user given. This allows if two
            instances of the same service are running on the same machine
            they can be differentiated by the `service.name`.
    
            Also it allows for distributed services that run on multiple hosts to
            correlate the related instances based on the name.
    
            In the case of Elasticsearch the service.name could contain the cluster
            name. For Beats the service.name is by default a copy of the `service.type`
            field if no name is specified.
