Hi,
i'm using a Samsung 1725b NVMe on ESXi 7.0 and wonder what are people using to
- monitor the health (tbw, errrors, temperature)
- predict failures based on these (few) data
For a normal SSD, i get a lot of information when using
# esxcli storage core device smart get -d ID
| Parameter | Value Threshold Worst Raw |
| Health Status | OK | N/A | N/A | N/A |
| Media Wearout Indicator | 99 | 5 | 99 | 172 |
| Write Error Count | 100 | 10 | 100 | 0 |
| Power-on Hours | 92 | 0 | 92 | 151 |
| Power Cycle Count | 99 | 0 | 99 | 14 |
| Reallocated Sector Count | 100 | 10 | 100 | 0 |
| Drive Temperature | 69 | 0 | 63 | 31 |
| Write Sectors TOT Count | 99 | 0 | 99 | 39 |
| Read Sectors TOT Count | 99 | 0 | 99 | 40 |
| Initial Bad Block Count | 100 | 10 | 100 | 0 |
| Program Fail Count | 100 | 10 | 100 | 0 |
| Erase Fail Count | 100 | 10 | 100 | 0 |
| Uncorrectable Error Count | 100 | 0 | 100 | 0 |
| Pending Sector Reallocation Count 100 | 0 | 100 | 0 |
For the NVMe i only have this:
| Parameter | Value Threshold Worst Raw |
| Health Status | OK | N/A | N/A | N/A |
| Power-on Hours | 1677 | N/A | N/A | N/A |
| Power Cycle Count | 3 | N/A | N/A | N/A |
| Reallocated Sector Count 0 | 90 | N/A | N/A | |
| Drive Temperature | 36 | 79 | N/A | N/A |
There were some efforts to get smartctl up and running, but everything unofficial.

Thanks for info.
