The context or the "label" of the event is a specification to narrow the scope of the event. When someone specifies 'job' they don't normally mean all jobs, so a context is required to determine which job they are describing. A context can be specified in 3 different forms:
- pre-defined label
- process group label (see: Job Labels)
- job ID
Pre-defined labels
| label | description |
|---|---|
| self | This job |
| parent | The job referred to by pid |
