| Attribute | Description | Example | Required |
|---|---|---|--|
| process.pid | Process identifier (PID). | `1234` | Yes |
| process.pid | Process identifier (PID). | `1234` | No |
| process.executable.name | The 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`. | `otelcol` | See below |
| process.executable.path | The 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/otelcol` | See below |
| process.command | The 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/otelcol` | See below |
| process.command_line | The full command used to launch the process. The value can be either a list of strings representing the ordered list of arguments, or a single string representing the full command. On Linux based systems, can be set to the list of null-delimited strings extracted from `proc/[pid]/cmdline`. On Windows, can be set to the result of `GetCommandLineW`. | Linux: `[ cmd/otecol, --config=config.yaml ]`, Windows: `cmd/otecol --config=config.yaml` | See below |
| process.command_line | The 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_args | 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.owner | The username of the user that owns the process. | `root` | No |
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.
| Attribute | Description | Example | Required |
|---|---|---|--|
| process.runtime.name | The name of the runtime of this process. For compiled native binaries, this SHOULD be the name of the compiler. | `OpenJDK Runtime Environment` | No |
| process.runtime.version | The version of the runtime of this process, as returned by the runtime without modification. | `14.0.2` | No |
| process.runtime.description | An additional description about the runtime of the process, for example a specific vendor customization of the runtime environment. | `Eclipse OpenJ9 openj9-0.21.0` | No |
At least one of `process.executable.name`, `process.executable.path`, `process.command`, or `process.command_line` is required.
`process.runtime.name` SHOULD be set to one of the values listed below, unless more detailed instructions are provided.
If none of the listed values apply, a custom value best describing the runtime MAY be used.
