Yep, it would not be temporary for troubleshooting. And even for troubleshooting, I don't know if prod guys would easily accept to load a module. > Can you explain what you like to do? I would like to be notified on vif updates for monitoring purposes. I would like to enable this monitoring as close as possible from the vrouter agent. But more generally, I think it could be useful to be able to monitor vrouter operations without having to load modules. For instance, when there are some performance issues regarding vif creation, it could really help to get vrouter operations in realtime. > Édouard. > > On Wed, Dec 7, 2016 at 4:49 PM, <l...@abesis.fr> wrote: > >> Édouard Thuleau <edouard.thul...@gmail.com> writes: >> >> > Hi Antoine, >> > >> > Did you had a look to the tools developed by Sylvain >> > https://github.com/safchain/vr_nldump ? >> >> Hi Édouard, >> >> Thanks for your link.
