-====== Installer l'agent Telegraf via Docker ======
-  * Se connecter en tant qu'admin : ''ssh admin@db-<region>-sinp''
-  * Se placer dans le dossier : ''cd ~/docker/telegraf''
-    * Lancer le container afin d'afficher les logs : '' docker-compose up ''
-    * Corriger les éventuels problèmes de configuration de Telegraf s'affichant dans les logs
-    * Lorsque tout fonctionne correctement, lancer le container en tant que service (option ''-d'') : ''docker-compose up -d''
-===== Monitorer différents services spécifiques =====
-  * Nginx:
-    * status
-    * access log
-  * Postgresql :
-  * Gunicorn : [[serveurs:installation:web-srv:monitorer-gunicorn|Doc monitorer Gunicorn GeoNature]]
-===== Exemple de fichier telegraf.conf complet =====
-Exemple avec :
-  * le support d'InfluxDB v2 accessible sur le port 8086 de l'ip privée 10.0.1.10
-  * le statut de Nginx sur http://172.18.5.1:9090/nginx_status (voir config Nginx),
-  * l'analyse des logs de Nginx via Tail et Grok,
-  * la surveillance de Postgresql
-  * la surveillance des service du système à l'aide du script //srvstatus//
-  * la surveillance de Gunicorn pour GeoNature à l'aide de Statsd
