@christianhorn, could you post the output of "lsblk" along the outputs from "smartctl -Hi" and "smarctl -A" from one of the systems that you are seeing issues with? |

Add support in the S.M.A.R.T PMDA for health attributes from NVME disks using smartctl output and following the attributes listed in the NVME Express 1.4a Specification. It turns out that SATA SSD and NVM Express SSD have completely different S.M.A.R.T listing in both attributes and format. This patch add the support along with new "smart.nvme_attributes.*" metrics. Included is an updated and expanded QA test 1379 that covers testing an NVME disk input and Valgrind testing. This update satisfies github issue #901 "pmda-smart read almost no metrics..."

For nvme SSD's on multiple systems (Fedora 31, 32), I just get these metrics from pmda-smart:
smart.health
smart.info.device_model
smart.info.serial_number
smart.info.capacity_bytes
smart.info.sector_size
smart.info.rotation_rate
From looking at qa/smart/smart-root*, it seems like the output of "smartctl -a" has changed since the pmda was written. The QA suite was simply always using the data from the older versions, and did not catch this.
The text was updated successfully, but these errors were encountered:
