Option to Show VM Bandwith in Kbps / Mbps

[Proxmox India]

Bandwith is usually measured in Kbps / Mbps vs MBps
Why not give an option to do this as data transfer is measured in bytes and bandwidth is measured in bits

 

[Alwin]

Where do you observe this?

 

[Proxmox India]

Hi Alwin,
In the Network Traffic, VM Summary area where we see the CPU, Memory, Disk and bandwidth graphs

 

[nojah]

I would also very much like to see this.

@Alwin I would also like to see the same option. Proxmox 6 also seems to have messed up the bandwidth graphs, and they're no longer accurate. This wasn't the case in 5.5 before I migrated to 6 - pve-manager/6.0-11/2140ef37 (running kernel: 5.0.21-4-pve). What's accurate is the node search list, as far as totals, but the vm summary no longer shows the traffic correctly (far less than in actuality).

 

[Alwin]

@Andrei ZeeGiant, how do you measure the traffic to see a difference?

 

[Andrei ZeeGiant]

The easiest way to see the difference is going to the Datacenter >> Node: Search view, and enabling netin/out columns. Those values are correct. However, when I go to Datacenter >> Node >> Container >> Summary, or Datacenter >> Node >> Summary, the "Network Traffic" section doesn't show the traffic to justify the numbers in the "Search" view. This was most visible to me when I just moved all my containers over to a new node. Should be easy to reproduce by starting up a new container, and looping downloads of 100MB test files. Most of my container traffic was around 5mbit at the time (not sure if that matters for how the graphs are drawn).

 

[Alwin]

The graph on each CT/VM is not the total netin/netout. The total is the traffic since startup of the CT/VM.

 

[Andrei ZeeGiant]

Yes, I already know that. It doesn't change a thing. You can easily test by restarting a VM, running 1-5Mbit traffic for an hour, then compare the average/maximum speeds listed in the VM summary to the netin/netout values. They don't match, no matter how you do the math or compare plotting. netin/out will show high values, while the vm network summary will show close to no traffic recorded. You get what I'm saying?

 

[Alwin]

The interval on the graph is one minute and data points are taken every 10 sec. And the graph is in MB, the total is in MiB.

#client
iperf -t 120 -b 200M <ip>
 
# server
iperf -s

Try with iperf, the two minute run should show a constant bandwidth. The total should account for the amount passed through by iperf (show stats).

To add, the totals are reset on every change of the interface (eg. firewall on/off).

Would be nice to find abusers if you offering VPS Services to customers.

But until its implemented or thought of as an option to implement note you guys can use something like:

Virtualizor
Modulesgarden Proxmox Addon(If using WHMCS)

We using Virtualizor currently and not sure how they calculate it but it seems to work well. They probably dump the traffic between start and stops and just keeping adding them up for total between a certain period.

Thanks for explaining the bandwidth measurements. I was off due to that seems like.

Do you prefer Virtualizor over Modulesgarden? I was thinking of grabbing the Modulesgarden WHMCS addon to resell easier but Virtualizor seems cheaper.

Seriously, the solution is to download and pay for another control panel to run on top of Proxmox? Why am I paying a Proxmox subscription then? It's 8 months since this was posted how is it not fixed?

 

[Alwin]

Why am I paying a Proxmox subscription then?

The subscription is for updates through the enterprise repository and if the subscription includes it, then also enterprise support through our support portal. This subscription does not include any performance monitoring tooling. This is usually done with a separate software (eg. icinga, zabbix, ...).

It's 8 months since this was posted how is it not fixed?

What should be fixed? In any case, feature requests can be added to our bugzilla.
