named mesgs in syslog

[Phua Cheng Ching]

There are some "named" statistics messages in syslog . Is there some document which describe the following/parameters

The only 'official' documentation I've seen is the source code (but I haven't really looked for anything else :) Here's what they mean:

>>Aug 30 08:54:25 bb-dns2 named[447]: USAGE 999132865 996638066 CPU=75.74u/128.95s CHILDCPU=0.06u/0.04s

The first two are the current time and named process start time respectively. Then you have the user and system mode CPU usage.

>>Aug 30 08:54:25 bb-dns2 named[447]: NSTATS 999132865 996638066 A=24006 SOA=8326 PTR=4967 MX=2 AXFR=2 ANY=3

The number of queries the name server has responded to, by type.

These are the BIND transaction statistics. Straight out of the code:

static const char *statNames[nssLast] = {
"RR", /* sent us an answer */
"RNXD", /* sent us a negative response */
"RFwdR", /* sent us a response we had to fwd */
"RDupR", /* sent us an extra answer */
"RFail", /* sent us a SERVFAIL */
"RFErr", /* sent us a FORMERR */
"RErr", /* sent us some other error */
"RAXFR", /* sent us an AXFR */
"RLame", /* sent us a lame delegation */
"ROpts", /* sent us some IP options */
"SSysQ", /* sent them a sysquery */
"SAns", /* sent them an answer */
"SFwdQ", /* fwdd a query to them */
"SDupQ", /* sent them a retry */
"SErr", /* sent failed (in sendto) */
"RQ", /* sent us a query */
"RIQ", /* sent us an inverse query */
"RFwdQ", /* sent us a query we had to fwd */
"RDupQ", /* sent us a retry */
"RTCP", /* sent us a query using TCP */
"SFwdR", /* fwdd a response to them */
"SFail", /* sent them a SERVFAIL */
"SFErr", /* sent them a FORMERR */
"SNaAns", /* sent them a non autoritative answer */
"SNXD", /* sent them a negative response */
};
