**Table 1** Scoring rules of TaurusDB instances
Deduction Item	Description	Sub-item	Condition	Calculation Rule
Memory usage	Average memory usage per day	Major event	Memory usage > 90%	min[3 + (Memory usage-0.9) x 50, 10]
Memory usage	Average memory usage per day	Warning	80% ≤ Memory usage ≤ 90%	1 + (Memory usage – 0.8) × 20
CPU usage	Average CPU usage per day NOTE: Multi-core CPUs need to be converted to single-core CPUs.	Major event	CPU usage ≥ 80%	min[3 + (CPU usage – 0.8) × 30, 10]
CPU usage		Warning	70% ≤ CPU usage ≤ 80%	1 + (CPU usage – 0.7) × 20
Connection rate	Average connections per day/Maximum of connections allowed in a day	Major event	Connection rate > 80%	3
Connection rate		Warning	70% ≤ Connection rate ≤ 80%	1
Active sessions	Active sessions generated in a day	Major event	Active sessions > min(4 × CPU cores + 8, 96)	9
Active sessions	Active sessions generated in a day	Warning	Active sessions > min(2 × CPU cores + 8, 64)	3
Slow SQL statements	Slow SQL statements executed per day	Major event	Slow SQL statements ≥ 500	18 + (Slow SQL statements – 10)/30
		Warning	100 ≤ Slow SQL statements < 500	4 + (Slow SQL statements - 100)/30
		Optimization	0 < Slow SQL statements < 100	1 + (Slow SQL statements – 10)/30
