Mwan3 uptime and online time

I have multiwan3 installed and working perfectly, if i check on luci it tells me uptime of wan interfaces and ONLINE uptime. Now i need to know where does luci gets wans ONLINE UPTIME information.. In all files I check the only stored information i found is interface uptime (how USELESS) not ONLINE Time which can apparently only be found on luci website.. Is there a SECRET command line or file how I can get this info?

On luci is
Status>load balancing>details and a page appears MWAN STATUS with all detailed information I need (and even more) it looks like it is reading from a file..

o i finally found what i need...
from terminal
mwan3 interfaces

i hope someone else find this useful
