Host Attributes

host.archstringThe CPU architecture the host system is running on.amd64
host.cpu.cache.l2.sizeintThe amount of level 2 memory cache available to the processor (in Bytes).12288000
host.cpu.familystringFamily or generation of the CPU.6; PA-RISC 1.1e
host.cpu.model.idstringModel identifier. It provides more granular information about the CPU, distinguishing it from other CPUs within the same family.6; 9000/778/B180L
host.cpu.model.namestringModel designation of the processor.11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz
host.cpu.steppingintStepping or core revisions.1
host.cpu.vendor.idstringProcessor manufacturer identifier. A maximum 12-character string. [1]GenuineIntel
host.idstringUnique host ID. For Cloud, this must be the instance_id assigned by the cloud provider. For non-containerized systems, this should be the machine-id. See the table below for the sources to use to determine the machine-id based on operating system.fdbf79e8af94cb7f9e8df36789187052
host.image.idstringVM image ID or host OS image ID. For Cloud, this value is from the provider.ami-07b06b442921831e5
host.image.namestringName of the VM image or OS install the host was instantiated from.infra-ami-eks-worker-node-7d4ec78312; CentOS-8-x86_64-1905
host.image.versionstringThe version string of the VM image or host OS as defined in Version Attributes.0.1
host.ipstring[]Available IP addresses of the host, excluding loopback interfaces. [2][, fe80::abc2:4a28:737a:609e]
host.macstring[]Available MAC addresses of the host, excluding loopback interfaces. [3][AC-DE-48-23-45-67, AC-DE-48-23-45-67-01-9F]
host.namestringName of the host. On Unix systems, it may contain what the hostname command returns, or the fully qualified hostname, or another name specified by the user.opentelemetry-test
host.typestringType of host. For Cloud, this must be the machine type.n1-standard-1

[1]: CPUID command returns the vendor ID string in EBX, EDX and ECX registers. Writing these to memory in this order results in a 12-character string.

[2]: IPv4 Addresses MUST be specified in dotted-quad notation. IPv6 addresses MUST be specified in the RFC 5952 format.

[3]: MAC Addresses MUST be represented in IEEE RA hexadecimal form: as hyphen-separated octets in uppercase hexadecimal form from most to least significant.

host.arch 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.
