Container

Container Attributes

Attribute	Type	Description	Examples	Stability
container.command	string	The command used to run the container (i.e. the command name). [1]	otelcontribcol
container.command_args	string[]	All the command arguments (including the command/executable itself) run by the container. [2]	[otelcontribcol, --config, config.yaml]
container.command_line	string	The full command run by the container as a single string representing the full command. [2]	otelcontribcol --config config.yaml
container.cpu.state	string	The CPU state for this data point.	user; kernel
container.id	string	Container ID. Usually a UUID, as for example used to identify Docker containers. The UUID might be abbreviated.	a3bf90e006b2
container.image.id	string	Runtime specific image identifier. Usually a hash algorithm followed by a UUID. [2]	sha256:19c92d0a00d1b66d897bceaa7319bee0dd38a10a851c60bcec9474aa3f01e50f
container.image.name	string	Name of the image the container was built on.	gcr.io/opentelemetry/operator
container.image.repo_digests	string[]	Repo digests of the container image as provided by the container runtime. [3]	[example@sha256:afcc7f1ac1b49db317a7196c902e61c6c3c4607d63599ee1a82d702d249a0ccb, internal.registry.example.com:5000/example@sha256:b69959407d21e8a062e0416bf13405bb2b71ed7a84dde4158ebafacfa06f5578]
container.image.tags	string[]	Container image tags. An example can be found in Docker Image Inspect. Should be only the <tag> section of the full name for example from registry.example.com/my-org/my-image:<tag>.	[v1.27.1, 3.5.7-0]
container.label.<key>	string	Container labels, <key> being the label name, the value being the label value.	container.label.app=nginx
container.name	string	Container name used by container runtime.	opentelemetry-autoconf
container.runtime	string	The container runtime managing this container.	docker; containerd; rkt

[1]: If using embedded credentials or sensitive data, it is recommended to remove them to prevent potential leakage.

[2]: Docker defines a sha256 of the image id; container.image.id corresponds to the Image field from the Docker container inspect API endpoint. K8s defines a link to the container registry repository with digest "imageID": "registry.azurecr.io /namespace/service/dockerfile@sha256:bdeabd40c3a8a492eaf9e8e44d0ebbb84bac7ee25ac0cf8a7159d25f62555625". The ID is assinged by the container runtime and can vary in different environments. Consider using oci.manifest.digest if it is important to identify the same image in different environments/runtimes.

[3]: Docker and CRI report those under the RepoDigests field.

container.cpu.state has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value	Description	Stability
user	When tasks of the cgroup are in user mode (Linux). When all container processes are in user mode (Windows).
system	When CPU is used by the system (host OS)
kernel	When tasks of the cgroup are in kernel mode (Linux). When all container processes are in kernel mode (Windows).
