Description:

The collectd package has not been complied with the IPMI plugin. This results in the following error reported in journalctl when the plugin is used:

plugin_load: Could not find plugin "ipmi" in /usr/lib/collectd

The plugin does appear in /etc/collectd.conf.

According to https://collectd.org/wiki/index.php/Plugin:IPMI this plugin requires the Open IPMI library, which is packaged in AUR as https://aur.archlinux.org/packages/openipmi/.

I operate several Arch Linux-based servers and IPMI provides a highly convenient mechanism to capture many sensors (fans, temperature, voltages, PSU status etc). I would therefore like the collectd package to enable the IPMI plugin, as many of these sensor values are simply unavailable via other collectd plugins.

https://wiki.archlinux.org/index.php/Arch_packaging_standards states "The submitted PKGBUILDs must not build applications already in any of the official binary repositories under any circumstances. Exception to this strict rule may only be packages having extra features enabled and/or patches in comparison to the official ones. In such an occasion, the pkgname array should be different".

I am happy to maintain a dedicated AUR package that includes the IPMI plugin if this is desired. I'd suggest it be named "collectd-extras" so it may include other AUR library dependencies that emerge in the future, although "collectd-ipmi" or similar is fine too. Or of course I'd be even happier if the community package added IPMI given it's so useful for server deployments.

Steps to reproduce:

1. Edit /etc/collectd.conf
2. Uncomment the "#LoadPlugin ipmi" line
3. Uncomment the "#<Plugin ipmi>" section
4. systemctl restart collectd.service
5. journalctl _SYSTEMD_UNIT=collectd.service -f, noting the plugin_load error line
