The "Storage Pools Health Score" is calculated in the following way:
This data is a derived metric, so the data is recalculated on the fly whenever new data for a pool is submitted. It works the following way:
1. Starting score: 75%
2. If long term (preferred) or short term predictive data is available, the starting score is reset:
a. < 14 days to full : set to 10%
b. < 28 days to full : set to 35%
c. < 84 days to full : set to 50%
d. > 300 days to full : set to 100%
e. > 200 days to full : set to 85%
f. > 100 days to full: set to 70%
3. From the starting score, we adjust based the percent of free space available:
a. < 10% : score adjusted -30%
b. < 20% : score adjusted -20%
c. < 30% : score adjusted -10%
d. > 90% : score adjusted +30%
e. > 80% : score adjusted +20%
f. > 70% : score adjusted +10%
4. Any computed values over 100 are changed to 100%
5. Any computed values < 0 are changed to 0%
