Disk utilization of "/boot" exceeds 90%

Hello,
You need to purge old kernels
Check which kernel you are using now, if not latest - reboot to switch to it.
Then remove all unused. There are two ways, or manually or with app:

That sounds a good idea.

That depends on your OS. If it's RH alike, so Centos or Almalinux, you can edit the /etc/yum.conf file and change this:
The default in Centos is 5 if I'm correct. So I set this to 3 for the same reason and that's enough. But you can also set it to 2 if you have 3 now.
installonly_limit=3The default in Centos is 5 if I'm correct. So I set this to 3 for the same reason and that's enough. But you can also set it to 2 if you have 3 now.
/boot doesn't really need a lot of disk space anyway. It's not like random stuff is being written there while the server is running. It just stores the kernel. Keeping 4 old kernels is probably a bit of overkill - but that is the default. yum will remove the oldest kernel before it installs a new kernel anyway, so it just keeps rotating them out.
90% usage in /boot is not the same thing as 90% usage in /home or /var - where stuff is being written to all the time.

Yes that is correct, it's a rather fairly static usage.
Only the kernels and additional files have become a bit bigger over the years.
Several years ago it was enough to have a 500 MB boot partition. Nowadays we create a boot partition of 1 GB.
But if one shortens the amount of kernels being kept, 500 MB is still enough.
