The .NET agent tracks certain system and application metrics. Some of them have built-in visualizations and some can only be visualized with custom Kibana dashboards.
These metrics will be sent regularly to the APM Server and from there to Elasticsearch.
You can adjust the interval with the setting MetricsInterval.
The metrics will be stored in the apm-* index and have the processor.event property set to metric.
"Platform: all" means that the metric is available on every platform where .NET Core is supported.
As of APM version 6.6, these metrics will be visualized in the APM app.
For more system metrics, consider installing {metricbeat-ref}/index.html[metricbeat] on your hosts.
