Logstash est installé sur un serveur local. Les logs du serveur local analysés sont envoyés à un serveur Elasticsearch kibana centralisé. Les logs analysés sont affichés par kibana. Pourtant, dans les logs de logstash, on a les erreurs ci-dessous.

```auto
logstash_front | [2019-05-29T11:55:56,637][ERROR][logstash.outputs.elasticsearch] Attempted to send a bulk request to elasticsearch' but Elasticsearch appears to be unreachable or down! {:error_message=>"Elasticsearch Unreachable: [http://<adr_ip>:9200/][Manticore::SocketTimeout] Read timed out", :class=>"LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError", :will_retry_in_seconds=>2}
logstash_front | [2019-05-29T11:55:57,920][WARN][logstash.outputs.elasticsearch] Restored connection to ES instance {:url=>"http://<adr_ip>:9200/"}

```

Avez-vous une idée sur la nature du problème?

> Elasticsearch appears to be unreachable or down!

Il semble qu'au moment de l'envoi de ces messages Elasticsearch n'était pas joignable.  
Ca peut être lié à une surcharge de ES, une panne réseau temporaire, un Old GC un peu long...

Peut-être que les logs ES t'en diront plus ?
