Data tiering monitoring

MemoryDB offers metrics designed specifically to monitor the performance clusters that use data tiering. To monitor the ratio of items in DRAM compared to SSD, you can use the CurrItems metric at Metrics for MemoryDB.. You can calculate the percentage as: (CurrItems with Dimension: Tier = Memory * 100) / (CurrItems with no dimension filter). When the percentage of items in memory decreases below 5 percent, we recommend that you consider Scaling MemoryDB clusters.
