[Orca-users] Displaying Statistics for NetApp SAN disks in Orca

[Ayotunde Itayemi (gmail)]

I went for the second regex which appears to be working fine. Thanks a lot.

Thanks David,

I am testing this right now. Can I assume that if I use any of the 2 regxp
you suggested below, it won't "break" the display of other "regular" disk
devices and SVM meta-devices?


I don't think it will.  The one problem that could come up is that the
letter following the "t\d+" part of the regex is also part of the
hexadecimal set, which introduces ambiguity into the pattern matching
algorithm.  In theory, it should be able to figure it out, and thus not
impact the graphs of your other disks either.

The 2nd regex is more explicit and because it does not include lower-case
'd' in the hex set, it would not have the ambiguity probelm that the first
regex does.

Good luck, and let us know how it works for you.

I have got the line below in my /usr/local/lib/orcallator.cfg file. How do I
modify this to show my external LUNs in addition to internal drives?

In particular the NetApp LUNs. 

disk_runp_((?:c\d+t\d+d\d+)|(?:c\d+d\d+)|(?:[ms]d\d+))

 

       4. c13t500A098387393451d0 <NETAPP-LUN-0.2-1.95TB>



That's a really awesome disk identifier.  The regexp above won't work,
because it's expecting the target to be a number, and in your case it's
hexadecimal.

First, try using \x after the 't':

disk_runp_((?:c\d+t\x+d\d+)|(?:c\d+d\d+)|(?:[ms]d\d+))
                   ^^

If that doesn't work, try the more verbose method:
disk_runp_((?:c\d+t[0-9A-F]+d\d+)|(?:c\d+d\d+)|(?:[ms]d\d+))
