Ubuntu Server 22.04 Services dead - dmesg.service

I have set up an Ubutnu server 22.04 and noticed that there are services that are not running (they are dead but status enabled).This also includesdmesg.service

When I check the status, it looks like this:sudo systemctl status dmesg.service

○ dmesg.service - Save initial kernel messages after boot     Loaded: loaded (/lib/systemd/system/dmesg.service; enabled; vendor preset: enabled)     Active: inactive (dead) since Tue 2024-07-09 16:01:17 CEST; 17h ago    Process: 1215 ExecStartPre=/usr/bin/savelog -m640 -q -p -n -c 5 /var/log/dmesg (code=exited, status=0/SUCCESS)    Process: 2026 ExecStart=/bin/journalctl --boot 0 --dmesg --output short-monotonic --quiet --no-pager --no-hostname (code=exited, status=0/SUCCESS)    Process: 2027 ExecStartPost=/bin/chgrp adm /var/log/dmesg (code=exited, status=0/SUCCESS)    Process: 2028 ExecStartPost=/bin/chmod 0640 /var/log/dmesg (code=exited, status=0/SUCCESS)   Main PID: 2026 (code=exited, status=0/SUCCESS)        CPU: 79ms

sudo systemctl start dmesg.service

sudo systemctl status dmesg.service

But I can actually look at dmesg:sudo dmesg

I checked it like this:

$ for i in $(systemctl list-unit-files --state=enabled | grep service | sort | cut -d" " -f1) ; do systemctl -q list-units --all $i --state=dead | column -t | cut -d " " -f1 ; done

• dmesg.service
• e2scrub_reap.service
• grub-common.service
• grub-initrd-fallback.service
• lxd-agent.service
• nginx.service
• open-iscsi.service
• pollinate.service
• secureboot-db.service
• snapd.autoimport.service
• snapd.core-fixup.service
• snapd.recovery-chooser-trigger.service
• snap.lxd.activate.service
• systemd-pstore.service
• thermald.service
• ua-reboot-cmds.service
• ubuntu-advantage.service

My question is: Do the services have to be dead or do I need to take action here?

It is a "normal" ubuntu server on which some services are running. I can deactivate the temperature sensor but what about the snap services?

Is this normal or is there a need for action? Which services should be running but are now dead?
