# Process - [Process](#process-attributes) - [Process Deprecated](#process-deprecated-attributes) ## Process Attributes An operating system process. | Attribute | Type | Description | Examples | Stability | | ----------------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------- | ---------------------------------------------------------------- | | `process.command` | string | 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` |  | | `process.command_args` | string[] | 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"]` |  | | `process.command_line` | string | 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"` |  | | `process.context_switch_type` | string | Specifies whether the context switches for this data point were voluntary or involuntary. | `voluntary`; `involuntary` |  | | `process.creation.time` | string | The date and time the process was created, in ISO 8601 format. | `2023-11-21T09:25:34.853Z` |  | | `process.executable.name` | string | 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` |  | | `process.executable.path` | string | 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` |  | | `process.exit.code` | int | The exit code of the process. | `127` |  | | `process.exit.time` | string | The date and time the process exited, in ISO 8601 format. | `2023-11-21T09:26:12.315Z` |  | | `process.group_leader.pid` | int | The PID of the process's group leader. This is also the process group ID (PGID) of the process. | `23` |  | | `process.interactive` | boolean | Whether the process is connected to an interactive shell. | |  | | `process.owner` | string | The username of the user that owns the process. | `root` |  | | `process.paging.fault_type` | string | The type of page fault for this data point. Type `major` is for major/hard page faults, and `minor` is for minor/soft page faults. | `major`; `minor` |  | | `process.parent_pid` | int | Parent Process identifier (PPID). | `111` |  | | `process.pid` | int | Process identifier (PID). | `1234` |  | | `process.real_user.id` | int | The real user ID (RUID) of the process. | `1000` |  | | `process.real_user.name` | string | The username of the real user of the process. | `operator` |  | | `process.runtime.description` | string | An additional description about the runtime of the process, for example a specific vendor customization of the runtime environment. | `Eclipse OpenJ9 Eclipse OpenJ9 VM openj9-0.21.0` |  | | `process.runtime.name` | string | The name of the runtime of this process. For compiled native binaries, this SHOULD be the name of the compiler. | `OpenJDK Runtime Environment` |  | | `process.runtime.version` | string | The version of the runtime of this process, as returned by the runtime without modification. | `14.0.2` |  | | `process.saved_user.id` | int | The saved user ID (SUID) of the process. | `1002` |  | | `process.saved_user.name` | string | The username of the saved user. | `operator` |  | | `process.session_leader.pid` | int | The PID of the process's session leader. This is also the session ID (SID) of the process. | `14` |  | | `process.user.id` | int | The effective user ID (EUID) of the process. | `1001` |  | | `process.user.name` | string | The username of the effective user of the process. | `root` |  | | `process.vpid` | int | Virtual process identifier. [1] | `12` |  | **[1]:** The process ID within a PID namespace. This is not necessarily unique across all processes on the host but it is unique within the process namespace that the process exists within. `process.context_switch_type` 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 | | ------------- | ----------- | ---------------------------------------------------------------- | | `involuntary` | involuntary |  | | `voluntary` | voluntary |  | `process.paging.fault_type` 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 | | ------- | ----------- | ---------------------------------------------------------------- | | `major` | major |  | | `minor` | minor |  | ## Process Deprecated Attributes Deprecated process attributes. | Attribute | Type | Description | Examples | Stability | | ------------------- | ------ | ----------------------------------- | ------------------------ | ------------------------------------------------------------------------------------- | | `process.cpu.state` | string | Deprecated, use `cpu.mode` instead. | `system`; `user`; `wait` | 
Replaced by `cpu.mode` | `process.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 | | -------- | ----------- | ---------------------------------------------------------------- | | `system` | system |  | | `user` | user |  | | `wait` | wait |  |
