  • 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

    https://www.elastic.co/guide/en/beats/filebeat/master/configuration-template.html

    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…

    Le système de plugin d'elasticsearch est vraiment bien foutu.

    Quelques plugins sympa pour avoir un aperçu de la santé de son cluster :
    https://github.com/karmi/elasticsearch-paramedic
    https://github.com/mobz/elasticsearch-head
    https://github.com/lukas-vlcek/bigdesk

    Pour les installer, c'est à chaque fois pareil, en une ligne :
    /usr/share/elasticsearch/bin/plugin -install lukas-vlcek/bigdesk
    /usr/share/elasticsearch/bin/plugin -install karmi/elasticsearch-paramedic
    /usr/share/elasticsearch/bin/plugin -install mobz/elasticsearch-head

    Pour savoir quels plugins sont installés et par quelle urls y accéder :
    curl -s -XGET 'http://localhost:9200/_nodes?pretty' | grep plugin

  • Why We Built Marvel | Blog | Elasticsearch

    Marvel, nouveau produit elasticsearch, pour résumer :

    The dashboard displays the essentials metrics you need to know that your cluster is healthy. The dashboard also provides an overview of your nodes and indices, displayed in two clean tables along with the relevant key metrics. These tables serve as an entry point to more details on the Node Statistics and Index Statistics dashboards, where you can see more than 90 different metrics plotted over time. Simply click on a table cell or select multiple nodes/indices to compare and you’ll be transferred to the relevant place in the detailed dashboard.

  • logstash - open source log management

    Logstash c'est bien.

    En fait c'est mieux avec ses deux copains : elasticsearch et kibana !

    Logstash permet de :
    1) récupérer "des choses" (parmi des input, comme par exemple des logs),
    2) de les traiter (par exemple, appliquer des regex pour récupérer des champs),
    3) de balancer la structure obtenue après traitement "quelquepart" (il existe des tas d'output, par exemple : elasticsearch)

    Une fois que vous avez ça en place, vous pouvez visualiser vos données stockées dans elasticsearch avec kibana! (et ça donne ça : http://www.elasticsearch.org/overview/kibana/)

    Sympa pour exploiter des access.log par exemple :)
