Network RRDs are gone

Here the same problem. But also my tun adapter (vpn connection) is missing in the network interfaces tab. But i'm connected with my VPN provider.

You can try this to reset your graphs. It will take some time to create new data points. You can click on refresh to see that it is working.

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

I was going to write a new thread because I had the same problem.
My solution was to edit /usr/sbin/omv-mkgrap (thir line of the file: # WARNING: Do not edit this file, your changes will be lost.)

I know change working directory may be not the best solution but it works for now. It's just a patch if you can wait and are so perfectionist as me.
Sorry, I don't know too much about shell script.

The solution I mentioned resolved this exact problem on 2 of my vms.

I already tried the reset rrdcached trick but it did not help. The only thing i'm missing is the network rrd. The rest is/was there.

I think you should try to get the tun adapter showing first. You should file a bug report to Volker on that. It may be why your network graphs are not working.

How i can open or see the Graph of the other Sensors?

Under /var/lib/rrdcached/db/localhost i can see a lot of folders with actually sensors.
Example "/var/lib/rrdcached/db/localhostsensors-coretemp-isa-0000/temperature-temp1.rrd". But how can i add or open it for a graph?

Same as Dropkick Murphy I tried this

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

It didn't resolve the network graphs for me, but its not the end of the world.

I've moved from nas4free, omv is a lot easier to setup and run. Thanks for the all the work.

I put what I did to solve the problem, it worked for me.

I saw that I'll try it tomorrow. thanks

How and where do I file a bug report?

(Have never done it before)...

Network RRD's fixed.
But still no TUN adapter.

Same as this one: 2.x upgrade - network monitoring graphs are missing

Just to let you know: after upgrading from 1.9 to 2.1 (without any incident) I had the same incident with the network interface statistics.
No statictics were displayed anymore for my network adapter. The other indicators were fine (CPU, disk, load, memory)

After some investigation I found /usr/sbin/omv-mkgraph, which had an 'error' in the code:

# Plugin: interface
...
for devicename in ; do

After adding a fake VLAN and deleting the VLAN the file omv-mkgraph was modified with this code:

# Plugin: interface
...
for devicename in eth0 ; do

This fixed the issue!

This fixed the issue!

Fixed it for me too (upgrade 1.8 -> 2.1.4, same problem, no eth0 devicename in /usr/sbin/omv-mkgraph)

Thanks

Hi,
Fixed it for me too (upgrade 1.19 -> 2.1.8, same problem, no eth0 devicename in /usr/sbin/omv-mkgraph)

Thanks
