circuit-id may not be there (if no line appears at
all in the logs), or if it only logs a partial line
then the circuit-id is likely binary instead of
ASCII. I'm not sure how to log if it is binary -
some use of binary-to-ascii will be necessary.<br>

would like my dhcpd logs to include circuit-id.<br>
I have tried to use log() directives in my conf
file, but nothing I have <br>
tried works.<br>
<br>
Here is an example of a configuration I have
included in a subnet:<br>
<br>
log(info, concat(<br>
" Mac: ",binary-to-ascii(16, 8, ":",
substring(hardware,1, 6))<br>
," IP: ",binary-to-ascii (10, 8, ".",
leased-address)<br>
,"Circuit: ",option agent.circuit-id<br>
));<br>
<br>
<br>
Standard logging is working fine to record
DHCPDISCOVER, DHCPOFFER, etc. <br>
I just can't get custom entries to show up in
the log.<br>
