# HDDtemp Input Plugin

This plugin reads data from a [hddtemp][hddtemp] daemon.

> [!IMPORTANT]
> This plugin requires `hddtemp` to be installed and running as a daemon.

As the upstream project is not activly maintained anymore and various
distributions (e.g. Debian Bookwork and later) don't ship packages for `hddtemp`
anymore, the binary might not be available (e.g. in Ubuntu 22.04 or later).

> [!TIP]
> As an alternative consider using the [smartctl][smartctl] relying on
> SMART information or [sensors][sensors] plugins to retrieve temperature data
> of your hard-drive.
