Missing SAN data from agent running on RHEL5 with QLogic HBAs

Hi,

REDHAT 5 does not populate tx_words or rx_words, so the collection for the san data is does not work.

[root@...... /]# cat /sys/class/fc_host/host1/statistics/tx_words
0xffffffffffffffff


https://bugzilla.redhat.com/show_bug.cgi?id=642424 (Mentions RHEL6 but..)


I've created a workaround to define it as 1, which allows me to get tx_frames / rx_frames.

         my $data = <FH>;
         chomp($data);
         close(FH);
-       $data = 1 if ($data eq '0xffffffffffffffff');
         if ( ishexa($data) == 1 ) {
           $tx_words = sprintf( "%d", hex($data) ) * 4;    # convert to Bytes
         }

         my $data = <FH>;
         chomp($data);
         close(FH);
-       $data = 1 if ($data eq '0xffffffffffffffff');
         if ( ishexa($data) == 1 ) {
           $rx_words = sprintf( "%d", hex($data) ) * 4;    # convert to Bytes
         }

Clunky, but so far seems OK

I only get IOPS and not throughput but better than nothing.

Thanks,
