Log Statement: How to log offered Lease Time?

[iftech at skynet.be]

Hello,

I can see Discover,Offer,Request,Ack in my log
What i am referring to is the detailed logging options that you can collect by using log statement
ex: log ( info, concat( "MSGTYPE", binary-to-ascii (16,8,"^", option dhcp-message-type)));

those seems only to work on Incoming DHCP messages (Discover, Request)
but not on Outgoing Offer and Ack

thanks
yves
