You wake up one morning to find your home server unresponsive, after some investigation you discover a failed NVMe drive taking your self-hosted services and data with it. Perhaps you’re a system administrator and a workstation’s SSD has been silently accumulating errors for months, and now a user is reporting corrupted files.
Drive failures are rarely instant, they give subtle warnings (through rising temperatures, increasing error counts, and wear indicators) but only if you’re watching. Most people will only check on disk health after problems start, by then it may be too late.
Performance Co-Pilot (PCP) is an open source framework for collecting, monitoring, and analyzing system performance metrics. Recent updates have expanded its drive monitoring capabilities with:
SMART metric collection for HDDs, SSDs, and NVMe drives
NVMe error log decoding with human-readable error messages
