There are several built in metricbeat modules you can use. To enable the system module, run the following:

metricbeat modules list
metricbeat modules enable system

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the system module.

/etc/metricbeat/modules.d/system.yml

By default the following metrics are enabled. To enable or disable a metric simply comment or uncomment the line out.

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

Start or restart to apply the configuration changes.

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.

The System module comes with predefined Kibana dashboards. To view your dashboards for any of your Logit.io stacks, launch Kibana and choose Dashboards.
