Bandwidth Graph on Fog 1.4.4 for Ubuntu Server 16.04.3 doesn't seem to function

[Sebastian Roth]

@n406c The only place I can think of is /var/www/fog/lib/pages/dashboardpage.class.php (line 133).

[n406c]

My apologies, I actually caused that error to appear in the log. I just remembered I tried to load that non existent page when troubleshooting through some old threads.

So we are back to square one. That’s OK. Let’s start with the basics. Can you give us screenshots of:

• Your bandwidth graph so we can see what it’s doing.
• The Node’s configuration in Web GUI -> Storage Management -> Node name
• The output of this command on your FOG Server: ip addr show

[n406c]

@wayne-workman Here you go.

@developers ideas?

[Tom Elliott]

@wayne-workman The fact that it’s missing the interface in the graph seems to be an indicator at least to me.

I have seen this from time to time in my development environment (because of switching things in and out).

You could try to ensure a link to the html fog folder exists in the fog folder. (I know that makes no sense, but it’s what works for me). NOTE: This is typically because the webroot is / instead of /fog

Please try running the command:

ln -s /var/www/html/fog{,/}

[n406c]

@tom-elliott I tried running that command but I get this response:

“ln: failed to create symbolic link ‘/var/www/html/fog/fog’: File exists”

[Sebastian Roth]

@n406c Wanna bring this back on screen. Do you know how to use the Firefox or Chrome Developer tools? Playing with those you should be able to if AJAX requests are working in general, plus you can take a look at the response.

[n406c]

@sebastian-roth Unfortunately, I do not have much experience with those tools. I also just upgraded to 1.5.0 and the bandwidth graph still does not show traffic while deploying an image.

[Tom Elliott]

@n406c From chrome type:

CTRL+SHIFT+C and you will be presented with a side bar (as default).

From there you have a tab list of options. Choose Console. Is there anything printing there?

[n406c]

@tom-elliott This is all that is shown in the console during an image deployment.

[Tom Elliott]

@n406c then im not quite sure of the problem as I cannot seem to replicate it. Do you using hostnames to access the fog server, or ip?

[n406c]

@tom-elliott Host name.

[Tom Elliott]

One thing I do notice is ens0p18 appears to not be up, though that would be extremely strange ad you can access the server gui just fine.

[Tom Elliott]

What if you access it using ip address?

[n406c]

@tom-elliott Strange indeed considering my image deployment is just about to complete. I just accessed the gui by IP while the deployment was at 90% and it still doesn’t work. One thing to note, I do believe “ens0p18” was displaying on the graph before I renamed the storage node name.

@n406c said in Bandwidth Graph on Fog 1.4.4 for Ubuntu Server 16.04.3 doesn't seem to function:

Can you set it back to the old name and see what happens?

[n406c]

@wayne-workman I set the storage node back to “DefaultMember”. The graph name now shows “DefaultMember ()” but chart still stays flat lined.

[n406c]

I finally had a chance to get a new gigabit network card on this machine and am happy to report the graph now functions properly. Thank you for your troubleshooting efforts.
