@docgyan I’m curious about the need to repost this. I’d noted in your previous post, Ingesting AKS(Azure Kubernetes Services) logs to Graylog - #2 by aaronsachs, that you’re probably going to need some other application (like FluentD) to ship container logs.
Are you running filebeat on the OS itself, or are you running it as a container? Can you provide the full filebeat configuration please?
