[Orca-users] Problem getting Orca to show disk stats with HP RAID adaptor

[Paul Woodward]

Hi all.

Using procallator/orca to gather stats on a database server running SuSE =
Linux (SLESx86-64).  It all looks good, except I'm not seeing any disk =
stats.  No such problems on my desktop PC running opensuse.

The database server has a hardware RAID controller, so we don't have the =
usual /dev/sda or /dev/hda style names (except for the CDROM - /dev/hda).  =
I think this is the issue, but I'm struggling to fix it.

I already found a 'bug' in procallator on line 438:      =20
        while ( $line =3D <F_DSKSTAT> ) {
            if ( $line =3D~ /sd|hd/ ) {    # just IDE or SCSI disks
                chomp $line;
                $line =3D " 0 " . $line

Now I'm no perl expert, but I think this basically says "if it doesn't =
contain sd or hd then don't capture it".

I've changed this to read:            =20
        if ( $line =3D~ /cciss/ ) {    # just RAID controller disks


The headers in the capture files in /usr/local/var/orca/procallator/
used to look like this:

timestamp locltime uptime 1runq 5runq 15runq #proc_oncpu #proc #proc/s =
#proc_blckd ncpus usr% nice% sys% wait% idle% usr_%_1 nice_%_1 sys_%_1 =

They now look like this:

...so I guess I'm grabbing the right stats now - But I still don't see =
anthing in the orca pages.

Anyone got any pointers?
