Aws network loadblancer metrics not captured

I am using metricbeat 7.8, elasticsearch 7.8 and kibana 7.8.

  • module: aws
    period: 1m
    regions:
    • eu-central-1
      metricsets:
    • elb

With the above configuration, only application load balancers are getting captured. Network load balancer data and metrics are not captured. Please suggest.

changing to 5m works.
