APM agents automatically pick up basic host-level metrics, including system and process-level CPU and memory metrics. Agent specific metrics are also available, like JVM metrics in the Java Agent, and Go runtime metrics in the Go Agent.
Infrastructure and application metrics are important sources of information when debugging production systems, which is why we’ve made it easy to filter metrics for specific hosts or containers in the Kibana metrics overview.
Metrics have the
processor.event property set to
Most agents limit keyword fields (e.g.
processor.event) to 1024 characters,
non-keyword fields (e.g.
system.memory.total) to 10,000 characters.
Metrics are stored in metric indices.
