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
