Heartbeat uses data streams named heartbeat-[version]. To use a different name, set the index option in the Elasticsearch output. You also need to configure the setup.template.name and setup.template.pattern options to match the new name. For example:
output.elasticsearch.index: "customname-%{[agent.version]}"
setup.template.name: "customname-%{[agent.version]}"
setup.template.pattern: "customname-%{[agent.version]}"
For a full list of template setup options, see Elasticsearch index template.
Remember to change the index name when you load dashboards via the Kibana UI.
