MONITOR DISK Filtering

Jack Trachtman — Wed, 26 Apr 2006 11:06:41 GMT

Is there any way to limit the output from MONITOR DISK to a subset of all of the disks?

For example, when I want to monitor all of our DSA disks, I have no interest in seeing the separate DGA disks that make up the shadow sets. And sometimes there is one or only a few disks in particular I'm interested in watching.

That's an old topic on the wishlist of many system admins...

Jack,

much in the same line as Peter Zeichler's

So, same advise: enter an Advocacy Request.
and maybe enter pointers to each other to mutually strenghten the idea.
One vote in favor promised!

Proost.

Have one on me (maybe in May in Nashua?)

I would love to see this capability.

Currently we see all of the DGA (SAN disks), DSA (Shadows of the disks), and DPA (raid sets of the disks).

Put my vote for AYE on filtering disks.

Thank you for bringing this to our attention
(again...;-)

I'll pass this to the developer of the
MONITOR utility, hopefully we'll be able
to do something for the next version.

This is number on on my VMS system management wish list.

In the mean time you might want to look into using Phil Ottewell's PERF_METER package. I believe you can set it up to do this, although it is Motif-based display so can't run on a dumb terminal display and therefore is slower than MONITOR.

(I was about to say slower than MONITOR's SMG display, but on my Alpha VMS 7.3-2 MONITOR is still a translated Vax image (written in PLI I think) that apparently doesn't even use the "new" (introduced around VMS 4.0 I think) SMG screen management API.

Jess, you will be glad to know that from V8.2 MONITOR was rewritten in another language as part of the port to Itanium and there is now more chance of enhancements.

Jack, add an issue at

and as people to vote. Five votes and there will be a response.

You can configure T4 to collect MONITOR DISK data for your systems and review specific device and combination of devices with TLViz. The default configuration doesn't do this, but a few simple updates provide this info.
