Note: Filebeat, elasticsearch et mapping

Filebeat utilise des template de mapping (pour chaque version de filebeat, un nouveau template est créé)
Donc l'index créé tous les jours par filebeat a un mapping qui provient de ce template
Il y a beaucoup de champs défini qui proviennent de la déclaration de tous les modules filebeat (https://github.com/elastic/beats/blob/master/filebeat/module/nginx/access/_meta/fields.yml)

Si on a besoin de déclarer de nouveaux champs, on peut créer son propre template qui va matcher aussi les index filebeat-* et qui va surcharger les templates de filebeat
Alternative : on peut vérifier que le champs n'existe pas déjà dans les champs prédéfini de filebeat. Par exemple le $status de nginx (code retour http) correspond au champs http.response.status_code
Il suffit que le json écrit par nginx ait une clé qui correspond pour le status pour avoir le bon mapping

elasticsearch filebeat mapping
Note: Repérer les inconsistences de mapping entre différents index

Exemple pour le field 'status' :

for index in $(cat liste_index); do echo $index; curl -s http://elastic/$index/_mapping | jq ".\"$index\".mappings.doc.properties.status"; done

JoliCode - Devez-vous migrer vers Elasticsearch 6 ?

Vous le savez peut-être, Algolia trie les documents lors de l’indexation, et non lors de la recherche. La raison est simple : c’est beaucoup plus rapide lors des recherches si les documents sont déjà triés sur le disque dur ! Cela permet, entre autre, de s’arrêter dès les dix premiers résultats trouvés – plutôt que de récupérer les 4 millions de hits et de les trier en mémoire juste pour remonter le top 10…

GitHub - abutaha/aws-es-proxy: aws-es-proxy is a small web server application sitting between your HTTP client (browser, curl, etc...) and Amazon Elasticsearch service.

Amazon Elasticsearch access control may be based on IAM account with signed request mechanism
One way not to rewrite all applications is using such a proxy
