Hi Guru, I would like to add vlog_info messages for datapath/actions.c. I see that none of the files in datapath support vlog.
I have added “#include <openvswitch/vlog.h>” and “VLOG_DEFINE_THIS_MODULE(dpactions)” to datapath/actions.c. What other changes do I need to make to perform a vlog/set to info for actions.c (ovs-appctl vlog/set dpactions:any:info) ?

Are you saying that you don't see any messages logged? Or are you saying that the messaged you want logged are not getting logged? And, I changed vlog/set as well.

It is specified that “—log-file” is used when “Regardless of the log levels set for file, logging to a FILE will not take place unless ovs-vswitchd was invoked with the --log-file option”. But, I am only trying to log to the console and not to a file. “—detach” seems to be an option which (as a side effect) disables logging to the console. I still do not understand why my ovs does not log to the console though I have enabled DBG level logging for all modules. Please let me know if I am missing something here. Paste your ovs-vswitchd arguments. Does it have -vconsole set?

But I tried printf, even vlog/set to DBG. Nothing gets printed though my OVS is working perfectly! Am I missing something ? *Side Note: I even tried with a print inside vport-internal_dev.c --> internal_dev_xmit(). That’s not the first function to be called when a packet enters ovs but it is pretty initial. That’s the one that calls ovs_vport_receive(). Any help is greatly appreciated!
