In the Foreman UI, Monitoring > Facts shows host fact values reported by Red Hat (mainly physical facts following a reboot), but no recent host facts reported by Puppet. This used to work, but the most recent Puppet facts showing are from 8 days ago, and things like uptime should be reported frequently.
Running puppet agent --test on the hosts completes successfully, but the facts don’t appear in the UI. Also, running facter -p on the hosts completes successfully and shows all the facts, but again they don’t show up in the Foreman UI.
We have had a similar issue when we updated from Puppet 6 to Puppet 7.
The cause on our end was that Puppetserver and the Foreman node.rb (ENC and fact upload script) where differently configured in terms of format for fact storage. Puppet 6 stored fact cache as yaml, while Puppet 7 defaults to storing facts as json. We somehow managed to mess that up and had Puppet configured to continue storing as yaml (in /etc/puppetlabs/puppet/routes.yaml) while the node.rb expected json (configured in /etc/puppetlabs/puppet/foreman.yaml).
Depending on the age of your environment and the installer options you used, it might also be your node.rb script is outdated (compare /etc/puppetlabs/puppet/node.rb with Github).
If both of these are not the issue, do you see any erros in the logs that might be related?
