But I don't got any log from DPDK, ether INFO or DEBUG, I use ovs2.8.0 like
this
[gangyewei@yf-mos-test-net07 gyw_ovs]$ git diff
[gangyewei@yf-mos-test-net07 gyw_ovs]$ git branch
* (detached from v2.8.0)
I use dpdk-17.05, and enable debugging like the mail defore
[gangyewei@yf-mos-test-net07 gyw_dpdk]$ git branch
* (detached from v17.05-rc1)
I set log level like you said:
[root@yf-mos-test-net07 vms]# sudo /usr/local/bin/ovs-appctl vlog/set
file:netdev_dpdk:dbg
[root@yf-mos-test-net07 vms]# sudo /usr/local/bin/ovs-appctl vlog/set
file:dpdk:dbg
[root@yf-mos-test-net07 vms]# sudo /usr/local/bin/ovs-appctl vlog/list |
grep dpdk
dpdk OFF ERR DBG
netdev_dpdk OFF ERR DBG
But I can't get DPDK log:
tailf /usr/local/var/log/openvswitch/ovs-vswitchd.log
BTW, I use this path to dump dpdk log before, this way could also NOT work
FILE *fp = fopen("/usr/local/var/log/openvswitch/dpdk.log", "a+b");
if (fp) {
rte_openlog_stream(fp);
}
BTW, I use gdb to debug ovs-vswitchd, and I set break point in rte_log(),
then I add port or something,
but I found I can't step into this function !!!
I don't know if there are any one who dump DPDK log in ovs2.8.0+dpdk17.05.1
