Summary: 0005047: no network activity reported
Description: Ganglia reports a constant 0 bytes/sec in/out network traffic for any server running Solaris 11.0 and above.
Steps To Reproduce:
Additional Information: libmetrics.so uses kstat to measure resource usage under Solaris. Solaris 11 changed the way network interfaces are named and how they appear in the kstat chain, thus breaking part of the code in libmetrics/solaris/metrics.c. Specifically, the following section of code in update_if_data() which loops over all interfaces:

      if (strcmp(info->ks_class, "net") == 0) {
         sprintf(buff, "%s%d", info->ks_module, info->ks_instance);
         if (strcmp(info->ks_name, buff) == 0) {
            extract_if_data(info);
         }
      }

should be changed to

     if ( (strcmp(info->ks_class, "net") == 0) && \
          (strcmp(info->ks_module, "link") == 0) ) {
         extract_if_data(info);
     }

to work under Solaris 11. The char array 'buff' is no longer needed.
