We use Graylog with logging tool. In my Rancher cluster, I set up for sending all logs for Graylog. I’m using Rsyslog protocol.
But I have some questions about it. When I configure my logging inside Rancher to use Rsyslog the message example doesn’t show “log message” (Error, actually state).
I hope that this feauture to be add soon!! But for the time I have used other way for… I’ve disabled log trought Rancher Admin Interface for all my clusters before I did deployed GELF with a daemonset inside my Kubernetes Cluster. By the way You’ll need deploy this solution for all your clusters. In my environment We have three cluster, so I needed to make three demonset deploy, one for each environment. I configured a port for each one.
