I want to enable builtin profiler for lock overhead
to get mutex statistics for BIND9.3.1 on HPUX.
I tried by modifying the following in ..bind-9.3.1/bin/named/main.c
if (want_stats) {
FILE *fp=NULL;
isc_mem_stats(ns_g_mctx, stdout);
fp = fopen("/home/mutex_stats", "w");
isc_mutex_stats(fp);
}
and also changed #define ISC_MUTEX_PROFILE 0 to #define ISC_MUTEX_PROFILE
1 in bind-9.3.1\lib\isc\pthreads\include\isc\mutex.h file.
after this I run the named process using #named -f -s -n 2
But i am unable to get the statistics in the file pointed by fp.
What more things i have to do to get statistics.
