OMV 5.2.3-2 (Usul) - GRAPHS not working after reboot/while

Hello all, may seem as "duplicated" question, but little different behavior (searched this problem before, tried every found solution).

- OMV 5.2.3-2 (Usul)
- Debian 10 (using netiso image)
- installed on harddrive (/home folder on separate partition)

At first there was clean installation of DEBIAN10 (I need secureboot for proper booting from my MoBo), then I used script to install OMV5. Everything is working fine, but graphs.
Several days I had no graphs shown, then I found some solution fo Raspberry etc. so I tried them.

I tried "omv-firstaid" and "Checked RRD database" - all fine without error. Then I tried "ovm-mkrrdgraph" and now I'm at situation, that graphs are working till next reboot (I'm not sure, it may be also "time related"). After that all graphs are ending and no new data displayed. If I want to fix this I have to do:

rm -r /var/lib/rrdcached/db/localhost
rm /var/lib/rrdcached/journal/*
service collectd restart
service rrdcached restart

After this, graphs are working again and logging (till next restart).

I may try to just restart those 2 services (collectd and rrdcached) - just momentary idea - to check whats going on. Any other clue what to check?

EDIT: I tried several things. It seems that after restart I have to run

service collectd restart

So there is probably some problem with collectd not starting automatically (confirmed using ps aufx | grep collectd). Looked at /etc/default/collectd, but not found anything suspicious (DISABLED = 0). What to check next?

Thanks!

OMG! In my language it say "statistics", not monitoring so I overwatched this. Thank you! And shame on me!
