The *sensors* plugin for collectd reads temperature information from the
I²C/SMBus using *lm_sensors*. Naturally, it is only useful on physical
machines, so it is not installed or enabled by default.
The groups in `hosts.offline` need to match those in `hosts`.
Specifically, the *collectd* group needs to be a child of the
*collectd-prometheus* group so that the *write_prometheus* plugin is
installed and configured on hosts defined in this inventory file.
Using *systemd-networkd* to configure network interfaces on *vmhost0* is
working really well. It is decidedly more stable than *dhcpcd* was, and
certainly easier to work with than NetworkManager. Let's go ahead and
switch *vmhost1* as well.
*vmhost0.pyrocufflink.blue* no longer uses `dhcpcd` for network
configuration, but *systemd-networkd*.
The host-specific network settings for a VM host include the
configuration for the management interface, as well as the configuration
of the physical ports that make up the bonded interfaces.
*systemd-networkd* is (currently) my preferred way to manage network
interfaces on machines running Fedora. The *systemd-networkd* role
provides a generic way to configure network links, devices, and
interfaces, using Ansible variables to generate network unit
configuration files.
I doubt I will be using Koji much if at all any more. In preparation
for decommissioning it, I am moving the Koji inventory to hosts.offline,
to prevent Jenkins jobs from failing.
*vmhost0.pyrocufflink.blue* is currently offline for maintenance. To
avoid the unending stream of failed continuous enforcement Jenkins jobs,
it has been removed from the main inventory file and moved to "offline"
inventory.
Because *vmhost1.pyrocufflink.blue* is usually sleeping, continuous
enforcement jobs always fail. By keeping it in a separate inventory
file, configuration policy can still be applied to it manually, but it
will be ignored by continuous enforcement.
