Performance Statistics are not Working OMV 4.1.23-1

SirACEair · 16. September 2019

Hi Community,
I started complete fresh with OMV and I think it is great.
But now I see a little Problem, wich is only cosmetic I think.
At the beginning the Performance Statistics were working fine. I can See all the Data (CPU, Network, Disk, and so on) in the Graphs. But after some time the Graphs are empty, also if i Click on Refresh.
As I saw that I search Google and the Forum and Found some Thing:
rm -r /var/lib/rrdcached/db/localhost
rm /var/lib/rrdcached/journal/*
service collectd restart
service rrdcached restart
That solved the Problem only for a few Hours, then the Graphs are still empty.
I tried omv-firstaid and the Point with RRD, there comes the Message everything is OK.

My System:
ASRock J3455-ITX
8GB RAM
4x 2TB Samsung Disk RAID5
1x 120GB SSD on USB Adapter (OMV System)

Has someone an Idea what could be the Problem?
Thank you all in advance
Andreas

Hello SirACEair,
I had a similar issue using OMV5 on a raspberry pi 4. I noticed the service collectd is not running and is disabled:
$ sudo service collectd status
● collectd.service - Statistics collection and monitoring daemon
Loaded: loaded (/lib/systemd/system/collectd.service; disabled; vendor preset: enabled)
Drop-In: /etc/systemd/system/collectd.service.d
└─openmediavault.conf
Active: inactive (dead)
Docs: man:collectd(1)
man:collectd.conf(5)
https://collectd.org
I started it and enabled it, the graphs are now working (for now 2 hours):
$ sudo service collectd start

$ sudo systemctl enable collectd
Synchronizing state of collectd.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable collectd
Created symlink /etc/systemd/system/multi-user.target.wants/collectd.service → /lib/systemd/system/collectd.service.

Jetzt mitmachen!
