Priorities
The tDie/tWarn components organize a Jobs exit using Priority Levels, an integer value, which are programmatically available in the DIE_PRIORITY and WARN_PRIORITY global variables, respectively. At lease one Priority Level must be selected.
These Priorities, which are industry standard, include:
| TRACE | Fine-grained informational events that track Job execution line by line |
| DEBUG | Medium-grained informational events that are most useful when debugging |
| INFO | Coarse-grained informational events to highlight execution process |
| WARNING | Potentially harmful events where execution process continues |
| ERROR | Problematic events where execution process may or may not continue |
| FATAL | Critical events where execution process aborts |
As TRACE and DEBUG Priority Levels can generate a huge amount of detail, the recommended best practice is to limit their use to actual debugging scenarios and rarely or never use them in a production environment.
For the remaining Priorities, the recommend best practice is to adopt programming conventions to be widely used across Jobs and projects within the enterprise.
