* Logging is, as everything in collectd, provided by plugins. The following
plugins keep up informed about what's going on:
Used by the `smart' plugin.

+ * libcap (optional)
+ The `turbostat' plugin can optionally build Linux Capabilities support,
+ which avoids full privileges requirement (aka. running as root) to read
+ values.
