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.'

naming scheme.
In the new data stream naming scheme the value of the data stream fields combine
to the name of the actual data stream in the following manner: `{data_stream.type}-{data_stream.dataset}-{data_stream.namespace}`.
This means the fields can only contain characters that are valid as part of
names of data streams. More details about this can be found in this https://www.elastic.co/blog/an-introduction-to-the-elastic-data-stream-naming-scheme[blog
post].
An Elasticsearch data stream consists of one or more backing indices, and a
data stream name forms part of the backing indices names. Due to this convention,
data streams must also follow index naming restrictions. For example, data stream
names cannot include `\`, `/`, `*`, `?`, `"`, `<`, `>`, `|`, ` ` (space character),
`,`, or `#`. Please see the Elasticsearch reference for additional https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html#indices-create-api-path-params[restrictions].'
