Diagnostic
A diagnostic in Omniscol is a consistency check run continuously by the system, which points out timetable configuration problems before they make the generation fail or produce an incorrect result.
Severity levels
- Critical (red, blocking) — prevents the generation from succeeding: structurally impossible alignment, insufficient total capacity, teacher without any free time slot…
- Warning (orange) — can be left as is but signals a risk or an inconsistency to review: imbalance in the aligned hour volumes, slightly undersized classroom, very restrictive availability.
- Information (blue) — non-blocking note: "some classrooms are never used", "a teacher has service hours well below those of their peers".
Where to see diagnostics
- In the top banner on the hours distribution screen and the timetable view.
- Next to the name of the class or teacher concerned in the lists.
- Detailed in the Generation tab (or checking depending on the timetable mode) with a contextual explanation for each diagnostic.
Frequent diagnostics
| Diagnostic | Typical cause | How to resolve |
|---|---|---|
| No compatible classroom | Required specialisation with no matching classroom | Create the classroom or remove the specialisation |
| Inconsistent hour volume in an alignment | One class has 2h, the other 3h on the same aligned group | Align the volumes, or unalign |
| Insufficient capacity | Headcount > classroom capacity | Assign a larger classroom, or several classrooms (multi-room) |
| Availability with no possible time slot | All time slots are marked impossible for this teacher | Relax the availability or redistribute the lessons |
| Lesson during an absence period | Lesson placed in a range where the teacher is absent | Move the lesson or remove the absence |
