A collector wrapped around smartctl for exporting SMART metrics to
Prometheus. The output of this collector is consumed by the Node
Exporter's textfile collector. No exporting functionality is provided
by this collector, the Node Exporter must be used.
Administrative permissions (root or admin capabilities) are required for
smartctl to query basic metrics. The benefit of the approach of this
collector is the exporter, which takes requests from clients, does not
need to run with administrative permissions. Only a small Python script
for the collector needs to run with these permissions. The Node Exporter
can continue to run as an unprivileged user, reading the file written by
the collector.
A Copr repo is provided for Fedora:
$ dnf copr enable jgeboski/prometheus-smart-collector
