Symptom
Cortex Data Lake Storage Used value in Panorama UI sometimes displays over 100%.
PANORAMA > Cloud Services > Status > Status > Cortex Data Lake
In the following picture, it shows 102%.
Environment
Cortex Data Lake
Prisma Access (Panorama managed)
Cause
In Cortex Data Lake, STORAGE USED(TiB) is calculated by dividing actual used storage (GB) with 1024.
In the following example, 6144.19(GB) / 1024 = 6.00 (TiB).
The value is TiB(TebiByte), not TB(TeraByte)
On the other hand, STORAGE USED(TB) is calculated by dividing actual used storage (GB) with 1000.
6144.19(GB) / 1000 = 6.14 (TB).
The value is TB, not TiB.
However, the percentage is calculated based on 6.00TB. Hence the percentage will be over 100%.
6.14(TB) / 6.00(TB) *100 = 102%
Resolution
As of the end of July 2023, This is expected behavior.
