      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.'

      For structured logs without an original message field, other fields can be concatenated

      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

      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.'

      information is likely logged with TLS sessions, digital signatures found in
      executable binaries, S/MIME information in email bodies, or analysis of files
      on disk.

      When the certificate relates to a file, use the fields at `file.x509`. When
      hashes of the DER-encoded certificate are available, the `hash` data set should
      be populated as well (e.g. `file.hash.sha256`).

      Events that contain certificate information about network connections, should
      use the x509 fields under the relevant TLS fields: `tls.server.x509` and/or
      `tls.client.x509`.'
