How to turn off gostats log

[ShyunnY]

I use ratelimit in kubernetes, and when I checked the logs, I found a lot of log output about gostats.

pod.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: "ratelimit-pod"
  namespace: default
  labels:
    app: "ratelimit"
spec:
  containers:
    - name: ratelimit-container
      image: envoyproxy/ratelimit:master
      command:
        - /bin/ratelimit
      env:
        - name: LOG_FORMAT
          value: json
        - name: LOG_LEVEL
          value: error
        - name: REDIS_SOCKET_TYPE
          value: tcp
        - name: REDIS_URL
          value: redis-service.default.svc.cluster.local:6379
        - name: RUNTIME_ROOT
          value: /data
        - name: RUNTIME_SUBDIRECTORY
          value: ratelimit
        - name: RUNTIME_WATCH_ROOT
          value: "false"
        - name: USE_STATSD
          value: "false"
        - name: MERGE_DOMAIN_CONFIG
          value: "true"
        - name: TRACING_ENABLED
          value: "true"
        - name: TRACING_EXPORTER_PROTOCOL
          value: "http"
        - name: TRACING_SERVICE_NAMESPACE
          value: "production"
        - name: TRACING_SERVICE_INSTANCE_ID
          value: "ratelimit-envoy"
        - name: OTEL_EXPORTER_OTLP_ENDPOINT
          value: "xxx"
      ports:
        - containerPort: 8080
        - containerPort: 8081
        - containerPort: 6070
      volumeMounts:
        - name: ratelimit-config
          mountPath: /data/ratelimit/config
          subPath: config
  volumes:
    - name: ratelimit-config
      configMap:
        name: ratelimit-config
        items:
          - key: demo.yaml
            path: config/demo.yaml
          - key: demo1.yaml
            path: config/demo1.yaml

k logs ratelimit-pod:

I tried configuring the environment variable with USE_STATSD=false but it doesn't seem to help me How can I prevent these gostats log output?
