You can tailor the log messages to output the subnet type.
Add the two "subnet_type"s (below in your config) and this to
dhcpd.conf:
on commit {
log ( info,
concat (
"Subnet-type", subnet_type,
.
.
)
);
}
Then in rsyslog.conf (just after the #### RULES #### line):
if $programname == 'dhcpd' then {
if $msg contains 'Faculty' then {
action(type="omfile"
file="/var/log/dhcpd/dhcp-faculty.log")
# if $syslogseverity >= 4 then stop #
warning
# if $syslogseverity >= 5 then stop # notice
if $syslogseverity >= 6 then stop # info
}
if $msg contains 'Student' then {
action(type="omfile"
file="/var/log/dhcpd/dhcp-student.log")
# if $syslogseverity >= 4 then stop #
warning
# if $syslogseverity >= 5 then stop # notice
if $syslogseverity >= 6 then stop # info
}
}
This should split out the log messages. Syslog facility 'notice'
and above still go to
the regular log file. Don't forget to restart or reload rsyslogd.

Can someone point me to a resource or
provide a configuration example of how to log dhcp transaction
(request/release/renew…) for each of the defined subnet/pools
to separate files?
For example:
Shared-network “Faculty”
Subnet 10.10.10.0 netmask
255.255.255.0 {
set subnet_type = "Faculty";
Option x
Option y
Range…
}
Shared-network “Student”
Subnet 10.10.20.0 netmask
255.255.255.0 {
set subnet_type = "Student";
Option x
Option y
Range …
}
Ideally it would be nice to log these
transaction to:
/var/log/dhcp/dhcp-faculty.log
/var/log/dhcp/dhcp-student.log
…
Any pointers are much appreciated!
Thank you.
