| # FTL: Wear Count |
| # |
| # A counter representing the highest wear count of the FTL driver. |
| # |
| # A NAND block has an expected lifetime in erase cycles. An erase must occur |
| # before anything can be written (updating data). |
| # |
| # This count is the highest number of erase cycles per block, across all |
| # erase blocks in the NAND device. |
| # |
| # This metric allows observing how the FTL wear leveling algorithm is performing, |
| # such that the device lifetime is maximized, because the higher the wear the |
| # more probable the block is expected to fail. |
| # |
| # Sampling Frequency: Once per FTL Driver initialization, usually once per boot. |
| # |
| # + |measured_at|: refers to the moment the metric was sampled during |
| # device's lifecycle. |
