So at the moment, the IP set here should be the IP of the InfluxDB instance on the same node. Then the Monasca API talks to InfluxDB via HAProxy, eg it has this in all instances of the Monasca API config file:\n\n```\n[influxdb]\ndatabase_name \u003d monasca\nip_address \u003d 192.0.2.10\nport \u003d 8086\n```\n\nThen HAProxy load balances over the replicas, eg:\n\n```\nbind 192.0.2.10:8086\n    server secondary1 192.0.2.2:8086 check inter 2000 rise 2 fall 5 \n    server secondary2 192.0.2.3:8086 check inter 2000 rise 2 fall 5 \n    server primary 192.0.2.1:8086 check inter 2000 rise 2 fall 5 \n```\n\nDoes that make sense, or did I miss something?","commit_id":"75c15e95656aff02df7f2923a628617dfeb66447"}]}
