Healthcheck

A health check is a procedure run periodically in every client. The purpose of a health check is to identify dead nodes/connections or bring them back to life after downtime.

By default, health checks are run every 60 seconds. However, you can set a different interval via elastic.SetHealthcheckInterval(...) when creating a new client.

client, err := elastic.NewClient(elastic.SetHealthcheckInterval(5 * time.Second))

You can also disable health checks altogether, although this might not be a good idea in production.

client, err := elastic.NewClient(elastic.SetHealthcheck(false))

Health checks play together with sniffing and requests.
