Re: rndc stats command
Hi, Thanks for your kind response. sorry for the delay. Currently i make a logic with shell scripts is that i run my statistics.sh by cron via every 1 minute and collect INCOMING QUERY AND CACHE HIT RATIO. CACHE HIT RATIO = (IN COMING QUERY - RECURSION ) / INCOMING QUERY. Let say i run first time : 10.00 AM First i clean named_Stat file and then run rndc stats command so it will write statistics to named_stat file and then i collect incoming query numbers and cache hit ratio. Second time run same logic : 10.01 AM so this time i again get incoming query numbers and hit ratio value and while plotting these by rrdtool, i remove old value ( 10.00 AM ) from current value ( 10.01 AM) and get actual value. same fashion, i run above logic for time frame. Kindly correct me , if i am running wrong logic. when i run rndc stats , it gives me full outpur.can i get only certain output from it by any command or something? My concern is that to find QPS / no. of queries per RR / hit ratio.

I think you are missing at least the following: rndc stats *appends* to the statistics file. It doesn't overwrite any previous contents. rndc stats does not reset the internal statistics counters (I take it that was what you meant by flush). They are always accumulative from when named was last started. From two successive set of ststistics written by rndc stats, you can deduce what happened during the interval by taking the difference in the values of corresponding counters, and to deduce rates you divide by the length of the interval which you can deduce from the difference in their timestamps +++ Statistics Dump +++ (1342566900) ... --- Statistics Dump --- (1342566900) ^^ which are in time_t format (seconds since the Unix epoch). [What's annoyingly missing, by the way, is the time when named was in fact started. That's present in the XML on the statistics channel, but not in the file written by rndc stats.] ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
