Need to know if fluentd can be setup to filter logs from azure kubernetes service before sending it

Hi,

I have a Kubernetes service setup in azure and have enabled insights for the same. I have created a log analytics workspace and a diagnostic setting to send all the logs to the log analytics workspace. In order for me to reduce the cost of data ingestion and implement log rotation i'm thinking of using fluentd.

So my approach would be to install the fluentd agent/docker image in the kubernetes service and filter it out before sending the logs to the log analytics workspace.

Is this approach even possible? If so please help me with few sources/reference links.
