Elasticsearch 9.3 ping endpoint (Ruby example)

Use client.ping to check whether the Elasticsearch server is reachable. Returns true if the server responds, false otherwise.

if client.ping
  puts 'Elasticsearch is available'
else
  puts 'Elasticsearch is not reachable'
end

Startup health check

Use ping at application startup to fail fast if Elasticsearch is unavailable:

unless client.ping
  warn 'Cannot connect to Elasticsearch — exiting'
  exit 1
end
