[ adding Song ] Song, I'm adding you to this thread for an opinion on what makes hardware monitoring tooling easier to consume in a production environment. QI is writing a daemon to catch alarms and notifications from the kernel's nvdimm sub-system.
QI, Song presented on extending SCSI uevents for storage device event logging at the last Linux Storage Summit.
