[mrtg] Re: Using an external program as a target

[Cam Bowman]

thanks..you suggestion does return a number, however the dhcpd.leases file seems to keep records for expired leases.  

I need some method to check if the "ends" field is less than or equal to the current time.
I'm not a programmer .. do you know how to do this?



dhcpd.leases example file.

lease 192.168.5.2 {
        starts 1 2000/03/06 14:15:32;
        ends 1 2000/03/06 18:15:32;
        hardware ethernet 00:10:a4:fa:b2:00;
        uid 01:00:10:a4:fa:b2:00;
        client-hostname "A0369";
}
lease 192.168.5.1 {
        starts 3 2000/03/01 21:45:54;
        ends 3 2000/03/01 21:47:13;
        hardware ethernet 00:60:97:91:a6:c2;
        uid 01:00:60:97:91:a6:c2;
        client-hostname "A0335";
}

man dhcpd.leases:

FORMAT
       Lease descriptions are stored in a format  that  is  parsed  by  the
same
       recursive   descent   parser   used   to   read   the   dhcpd.conf(5)
and
       dhclient.conf(5) files.   Currently, the only declaration that is
used  in
       the dhcpd.leases file is the lease declaration.

        lease ip-address { statements... }

grep lease /var/state/dhcpd.leases|wc -l

I dont have a populated dhcpd.leases to check that on, but itll get you a
number..
