No problem.

The only reason i know this is because systemd throws degraded warnings because fwupd keeps failing. On several machines. (Because DNS, proxies, VPN, etc.)

In xfce there’s a panel tool called genmon I use.

I have 2 specifically for monitoring systemd status

First is just the status

systemctl is-system-running

The other lists the failed units using a script

#!/bin/sh
failedd (){ systemctl --failed | grep -o -E "●.{0,35}\<failed" 2>/dev/null }
echo $(failedd)

Mint cinnamon has a similar “spice” (panel plugin) that I also use.
