High Disk Space Utilization

Hi, I have an alarm saying high disk space utilization on my secondary MNT node, but after checking it , I can see there is enough space.

disk repository: 14% used (1926708 of 14987616)

Internal filesystems:
/ : 45% used ( 6305272 of 14987616)
/dev : 0% used ( 0 of 8123160)
/dev/shm : 0% used ( 0 of 8133172)
/run : 1% used ( 776 of 8133172)
/sys/fs/cgroup : 0% used ( 0 of 8133172)
/storedconfig : 2% used ( 1582 of 95054)
/tmp : 1% used ( 6536 of 1983056)
/boot : 23% used ( 103788 of 487634)
/opt : 17% used ( 187699620 of 1212603984)
/run/user/440 : 0% used ( 0 of 1626636)
/run/user/301 : 0% used ( 0 of 1626636)
/run/user/321 : 0% used ( 0 of 1626636)
/run/user/0 : 0% used ( 0 of 1626636)
/run/user/304 : 0% used ( 0 of 1626636)
/run/user/303 : 0% used ( 0 of 1626636)
all internal filesystems have sufficient free space

as well as

Everyone else with this problem has 100% or close to 100% utilization on some directory , for me everything seems ok, but I still get the alarm raised.

I am on version 2.2 patch 17

Any ideas? or different commands to check space?

Hi, the output above is from show disk, as for the logging show, it seems I have quite a bit some logs, but not very old ones, most of them from 2021 and 2020, but how can I see the amount of space utilized ? the biggest ones being 15 MB so I don't think they use the space.

The earlier technical-thread I referred too offer options to examine the disks and or linux file system(s) more closely. If not possible then you have to coordinate that with TAC , which can offer a root-patch, to do the same local on the system.
