{beatname_uc} collects system metrics for interfaces you didn’t configure

The System module specifies several metricsets that are enabled by default unless you explicitly disable them. To disable a default metricset, comment it out in the modules.d/system.yml configuration file. If all metricsets are commented out and the System module is enabled, {beatname_uc} uses the default metricsets.

For example, to disable the network metricset, comment it out:

  - module: system
    period: 10s
    metricsets:
      - cpu
      - load
      - memory
      #- network
      - process
      - process_summary
      - socket_summary
      #- entropy
      #- core
      #- diskio
      #- socket

You cannot override the default configuration by adding another module definition to the configuration. There is no concept of inheritance. {beatname_uc} combines all module configurations at runtime. This enables you to specify module definitions that use different combinations of metricsets, periods, and hosts.
