LXC Bandwidth Cap

[Wojciech Szpunar]

Hi,

Can anybody point me into some documents for traffic limiting per VM?

Say I want to assign 1TB of traffic to VM and if VM will use that traffic then speed of connection goes down to say 1Mb/s.

Is there a way to do it in Proxmox?

there is no built in way to do this, but you could do the following:

log the traffic with the api from:
"/nodes/<nodename>/lxc/<ctid>/status/current"
(the netout and netin values)

and then script the traffic limiting
see the "rate" parameter of the netX devices

Hi,
Thanks a lot for that info

Hello,
when we create an LXC container in proxmox 4.3 and set the rate limit in the nettwork wizzard it doesn't work for outgoing network traffic .
any suggestion to solve this problem ?

this works here, how did you test?

 

[Medvenda]

for example if i create a new LXC with 2 MB/s rate limit and i test the download/upload, with download i can't exceeds the limit of 2 MB/s instead of upload

for example if i create a new LXC with 2 MB/s rate limit and i test the download/upload, with download i can't exceeds the limit of 2 MB/s instead of upload

The limiting rate is in both directions, so download and upload gets throttled

12TB per node? Will this perform will for hbase type stuff? or is that for purely an analytics point of view in that nothing is slamming the system like in the case of cassandra which is only about 1TB per node?

But in my case it's not limites just for the netin
