named.memstats file question

[Todd Herr]

Greetings,

I have a question on named.memstats output from BIND version 8.3.1.

Maybe it's me, but I just can't seem to lay hands on a good source of
documentation for the named.memstats file, with an emphasis on how to
parse it to get a feeling for how well one's nameserver is performing,
if in fact such information can be gleaned from this file.  Lines
such as the following:

    142:           2 gets,           0 rem
    144:         746 gets,           1 rem (1 bl, 27 ff)
    168:         943 gets,           1 rem (1 bl, 23 ff)
    169:           2 gets,           0 rem
    192:         552 gets,           1 rem (1 bl, 20 ff)
    196:           2 gets,           1 rem (1 bl, 19 ff)
    216:         939 gets,           0 rem (1 bl, 18 ff)
    240:        1558 gets,           0 rem (1 bl, 17 ff)
    256:           3 gets,           3 rem (1 bl, 13 ff)
    264:         811 gets,           0 rem (1 bl, 15 ff)
    288:         162 gets,           0 rem (1 bl, 14 ff)
    312:         120 gets,           0 rem (1 bl, 13 ff)
    336:         227 gets,           0 rem (1 bl, 12 ff)
    360:         189 gets,           0 rem (1 bl, 11 ff)
    384:          58 gets,           0 rem (1 bl, 10 ff)
    388:           6 gets,           0 rem (1 bl, 10 ff)
    408:          26 gets,           0 rem (1 bl, 10 ff)
    432:          58 gets,           0 rem (1 bl, 9 ff)
    456:          67 gets,           0 rem (1 bl, 8 ff)
    460:           9 gets,           9 rem (2 bl, 7 ff)
    480:          72 gets,           0 rem (1 bl, 8 ff)
    499:           5 gets,           0 rem

sure do look interesting as all get out, but I can't find anything
anywhere to tell me how to read them.  The 4th edition of DNS and BIND
makes reference to some neat tools at

    http://www.dns.net/dnsrd/tools.html

but, sadly, that site appears to be not accepting connections this
afternoon from my location.  :-(

Anyone got any pointers on how I might make use of these stats?

Thanks.
