Dev Builds IPSEC VPN Logging

I installed the latest development build, 999.201711232137, and put a basic config on it along with both IKEv1 and IKEv2 site VPNs in the configuration. I then checked the logs to see what is getting logged but it is showing absolutely nothing:

vyos@vyos:~$ show log vpn ipsec


I’m not quite sure what I’m missing to get logging enabled for the IPSEC VPNs. Any pointers on what to look for? I tried setting levels and enabling options in vpn ipsec logging but nothing appears to make a difference. I tested a previous build from October and had the same issue, but thought that maybe it was just that specific build. Now I’m wondering if I’m doing something wrong.
