Process and process runtime resources

Status: Experimental

Process

type: process

Description: An operating system process.

AttributeTypeDescriptionExamplesRequired
process.pidintProcess identifier (PID).1234No
process.executable.namestringThe name of the process executable. On Linux based systems, can be set to the Name in proc/[pid]/status. On Windows, can be set to the base name of GetProcessImageFileNameW.otelcolSee below
process.executable.pathstringThe full path to the process executable. On Linux based systems, can be set to the target of proc/[pid]/exe. On Windows, can be set to the result of GetProcessImageFileNameW./usr/bin/cmd/otelcolSee below
process.commandstringThe command used to launch the process (i.e. the command name). On Linux based systems, can be set to the zeroth string in proc/[pid]/cmdline. On Windows, can be set to the first parameter extracted from GetCommandLineW.cmd/otelcolSee below
process.command_linestringThe full command used to launch the process as a single string representing the full command. On Windows, can be set to the result of GetCommandLineW. Do not set this if you have to assemble it just for monitoring; use process.command_args instead.C:\cmd\otecol --config="my directory\config.yaml"See below
process.command_argsstring[]All the command arguments (including the command/executable itself) as received by the process. On Linux-based systems (and some other Unixoid systems supporting procfs), can be set according to the list of null-delimited strings extracted from proc/[pid]/cmdline. For libc-based executables, this would be the full argv vector passed to main.[cmd/otecol, --config=config.yaml]See below
process.ownerstringThe username of the user that owns the process.rootNo

Between process.command_args and process.command_line, usually process.command_args should be preferred. On Windows and other systems where the native format of process commands is a single string, process.command_line can additionally (or instead) be used.

For backwards compatibility with older versions of this semantic convention, it is possible but deprecated to use an array as type for process.command_line. In that case it MUST be interpreted as if it was process.command_args.

At least one of process.executable.name, process.executable.path, process.command, process.command_line or process.command_args is required to allow back ends to identify the executable.

Process runtimes

type: process.runtime

Description: The single (language) runtime instance which is monitored.

AttributeTypeDescriptionExamplesRequired
process.runtime.namestringThe name of the runtime of this process. For compiled native binaries, this SHOULD be the name of the compiler.OpenJDK Runtime EnvironmentNo
process.runtime.versionstringThe version of the runtime of this process, as returned by the runtime without modification.14.0.2No
process.runtime.descriptionstringAn additional description about the runtime of the process, for example a specific vendor customization of the runtime environment.Eclipse OpenJ9 Eclipse OpenJ9 VM openj9-0.21.0No

How to set these attributes for particular runtime kinds is described in the following subsections.

In addition to these attributes, telemetry.sdk.language can be used to determine the general kind of runtime used.

Erlang Runtimes

  • process.runtime.name - The name of the Erlang VM being used, i.e., erlang:system_info(machine).
  • process.runtime.version - The version of the runtime (ERTS - Erlang Runtime System), i.e., erlang:system_info(version).
  • process.runtime.description - string | An additional description about the runtime made by combining the OTP version, i.e., erlang:system_info(otp_release), and ERTS version.

Example:

process.runtime.nameprocess.runtime.versionprocess.runtime.description
BEAM11.1Erlang/OTP 23 erts-11.1

Go Runtimes

Go Runtimes should fill in the as follows:

  • process.runtime.name - Fill in an interpretation of Go’s runtime.Compiler constant, according to the following rule: If the value is gc, fill in go. Otherwise, fill in the exact value of runtime.Compiler.

    This can be implemented with the following Go snippet:

    import "runtime"
    
    func getRuntimeName() string {
      if runtime.Compiler == "gc" {
        return "go"
      }
      return runtime.Compiler
    }
    
  • process.runtime.version - Fill in the exact value returned by runtime.Version(), i.e. go1.17.

  • process.runtime.description - Use of this field is not recommended.

Examples for some Go compilers/runtimes:

process.runtime.nameDescription
goOfficial Go compiler. Also known as cmd/compile.
gccgogccgo is a Go front end for GCC.
tinygoTinyGo compiler.

Java runtimes

Java instrumentation should fill in the values by copying from system properties.

  • process.runtime.name - Fill in the value of java.runtime.name as is
  • process.runtime.version - Fill in the value of java.runtime.version as is
  • process.runtime.description - Fill in the values of java.vm.vendor, java.vm.name, java.vm.version in that order, separated by spaces.

JavaScript runtimes

JavaScript instrumentation should fill in the values by copying from built-in runtime constants.

  • process.runtime.name:
    • When the runtime is Node.js, fill in the constant value nodejs.
    • When the runtime is Web Browser, fill in the constant value browser.
  • process.runtime.version:
    • When the runtime is Node.js, fill in the value of process.versions.node.
    • When the runtime is Web Browser, fill in the value of navigator.userAgent.

Examples for some JavaScript runtimes

.NET Runtimes

Python Runtimes

Python instrumentation should fill in the values as follows:

  • process.runtime.name - Fill in the value of sys.implementation.name

  • process.runtime.version - Fill in the sys.implementation.version values separated by dots. Leave out the release level and serial if the release level equals final and the serial equals zero (leave out either both or none).

    This can be implemented with the following Python snippet:

    vinfo = sys.implementation.version
    result =  ".".join(map(
        str,
        vinfo[:3]
        if vinfo.releaselevel == "final" and not vinfo.serial
        else vinfo
    ))
    
  • process.runtime.description - Fill in the value of sys.version as-is.

Examples for some Python runtimes:

Nameprocess.runtime.nameprocess.runtime.versionprocess.runtime.description
CPython 3.7.3 on Windowscpython3.7.33.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD64)]
CPython 3.8.6 on Linuxcpython3.8.63.8.6 (default, Sep 30 2020, 04:00:38)

PyPy 3 7.3.2 on Linuxpypy3.7.43.7.4 (?, Sep 27 2020, 15:12:26)
[PyPy 7.3.2-alpha0 with GCC 10.2.0]

Note that on Linux, there is an actual newline in the sys.version string, and the CPython string had a trailing space in the first line.

Pypy provided a CPython-compatible version in sys.implementation.version instead of the actual implementation version which is available in sys.version.

Ruby Runtimes

Ruby instrumentation should fill in the values by copying from built-in runtime constants.

  • process.runtime.name - Fill in the value of RUBY_ENGINE as is
  • process.runtime.version - Fill in the value of RUBY_VERSION as is
  • process.runtime.description - Fill in the value of RUBY_DESCRIPTION as is
