How to set InfluxDB custom measurement name When I use Fluent-bit Tail plugin with Kubernetes filter

Question

When I use InfluxDB output plugins with Fluent-bit, I would like to set custom InfluxDB measurement name like the kubernetes. but, current measurement name that kubernetes logs stored is each log file name : kube.var.log.containers.apache-logs-annotated_default_apache-aeeccc7a9f00f6e4e066aeff0434cf80621215071f1b20a51e8340aa7c35eac6.log

This is my config file :

What should I do?

Answer 1

I solved this problem using rewrite_tag Filter.

 [FILTER]
        Name                rewrite_tag
        Match               kube.*
        Rule                $kubernetes_pod_name ^.*$ kubernetes_logs false

I used the image : fluent/fluent-bit:1.5
