Hello community. We have one Graylog node so far. But now want to scale up to 2 and put load balancer before them. One node has 1 input GELF on 12201 UDP port, how we should send logs after load balancer has been placed before 2 graylog nodes? Just send logs to load balancer, which in turn send them across all nodes behind?
And one question more. How we can check us is we actually need a load balancer and our nodes under load? Maybe some specific graylog metrics are? Because CPU not so much loaded according to Zabbix metrics.
