Hourly statistics... what do they mean ?

[Peter]

Hi,

I am wondering what the hourly stats mean, that bind puts into my
syslog. They have the tendency to look something like this:

Sep  8 13:33:26 tijgert named[14886]: XSTATS 968412806 968340805 RR=78  
RNXD=4 RFwdR=57 RDupR=4 RFail=0 RFErr=0 RErr=1 RAXFR=2 RLame=0 ROpts=0
SSysQ=14 SAns=87 SFwdQ=57 SDupQ=7 SErr=0 RQ=95 RIQ=0 RFwdQ=57 RDupQ=4
RTCP=4 SFwdR=57 SFail=0 SFErr=0 SNaAns=47 SNXD=8 RUQ=0 RURQ=0 RUXFR=0
RUUpd=0

Is there any documentation about what all these things mean, or could
anyone of you give me a list. Some a quite obvious (as RFwdR=57 probably
means that bind forwarded 57 requests to the other nameservers), others
don't make any sence to me?

Anyone have an idea ?

Peter.
