2.x upgrade - network monitoring graphs are missing

nomax · Jul 5th 2015

All,

I've updated recently from 1.9 to 2.x but it seems currently there is no possibility to monitor the network load now for the pre-defined timeframes. Under system performance/monitoring i can see only 'sad smilies' but no display of the network traffic.

Anybody in here familiar with this?

Thanknyou.

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

Just tried these commands - but the grey bars with those sad smilies are still in place (although i refreshed several times).

Look in /var/lib/rrdcached/db/localhost/interface-ethx (x is whatever interfacec you are using)

Do you see a recent time on the files in that folder??? We are checking to see if the files are being written to recently.

Are the other graphs working normally???

Will look later that day for the timestamp in the directory that you were requesting.

The other graphs are working properly - only the network interface is currently causing problems.

Are you using a static ip or dhcp???

nomax · Jul 6th 2015

the ip is static - i did not change this after the upgrade.

Just had a look - the files in the folder you specified have a brand new stamp, so it seems the logging itself still going to happen.

Your graphs should be working for network if you are seeing new time stamps..

Did you clear your browser cache??? Did you try another browser?

nomax · Jul 6th 2015

yes, cleared the cache and also changed the browser, still:

Hmm... we wait and see if Volker finds something.

I can replicate the issue. Problem appeared at the upgrade to 2.x, and it's only limited to the ETH0 graphs. Data is still being collected:

Code

root@openmediavault:/var/lib/rrdcached/db/localhost/interface-eth0# ls -lsa
total 884
  4 drwxr-xr-x  2 root root   4096 Sep 18  2014 .
  4 drwxr-xr-x 24 root root   4096 Jul  3 00:05 ..
292 -rw-r--r--  1 root root 295232 Jul  7 00:11 if_errors.rrd
292 -rw-r--r--  1 root root 295232 Jul  7 00:11 if_octets.rrd
292 -rw-r--r--  1 root root 295232 Jul  7 00:11 if_packets.rrd

It's just the graphs not being propery displayed.

For instance, the memory hourly graph works:

Code

<img src="rrd.php?name=memory-hour.png&amp;time=1436217329828" alt="RRD graph - by hour">

But the ETH0 doesn't:

Code

<img src="rrd.php?name=interface-eth0-hour.png&amp;time=1436217250759" alt="RRD graph - by hour">

I was plying with the idea to change eth0 to eth1 - but as my nas is currently placed just behind the desk and not that easy to get to, I wouldn't do experiments like that where I would obviously have to connect a monitor in case the device is not reachable on the net.

puterfixer · Jul 7th 2015

Why'd you bother with that, when obviously it's an issue of the graph generating script not referencing existing data correctly You could even disable the NIC and the script should still produce relevant graphs based on already collected history.

nomax · Jul 9th 2015

Is there any solution to solve this? the information on the network interface load is quite useful

pitas · Jul 13th 2015

Same here, no network graphs!!!

After upgrading to omv 2.1 my eth0 graphs don't work.

PS: I have a raspberry pi 2 box.

Mine is now fixed -> Disabling and re-enabling the monitor feature fixed it for me!!!

C0mmanda · Jul 13th 2015

Same here!
After upgrading to OMV 2.x no Network-Graphs!

nomax · Jul 15th 2015

After upgrading to 2.1.1 everything works back again - hooray!!

tekkb · Jul 15th 2015

A lot of times I see people where their graphs data is corrupted. These are best instructions I give to reset graphs with corrupted database.

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

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:

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:

Code

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

This fixed the issue!
