New Relic data dictionary

This data dictionary lists and defines the attributes attached to New Relic events and other data objects (like Metric and Span data).

This dictionary does not contain data reported by Infrastructure integrations. To learn about that data, see the integration documentation.

This event is reported by the New Relic Infrastructure agent. It collects data from all the Docker containers on the host (which may or may not be running). It includes the container's ID, name, image, image name, and metrics about CPU, memory and networking. We take a snapshot of this data every 15 seconds for each container and package it into this event, which is then sent to New Relic. This data appears on the Containers UI page.

Total attributes in this event: 39

Attribute name Summary
commandLine The command line used in the container.
containerId The unique Docker container ID.
cpuKernelPercent CPU time percentage used in kernel space.
