If i unsubscribe how am i going to query via loadbalancer? I tried : [[influxdb]] # Turn off all subscriptions disable-subscriptions = true but i still see in /var/log/kapacitor/kapacitor.log following messages that tells me the subscription is still happening: [noauth] 2016/11/04 15:18:20 W! using noauth auth backend.
