Extension Attribute for Displays/Monitors

[#1]

Hi Casper list, I was wondering if anybody is currently using an extension attribute to retrieve Display/Monitor info from your JSS clients. Basically I will like to get Model Name/Screen size based on the extension attribute. I'm trying to find the best approach for this task, any ideas/comments?

Thanks Guys!!

There might be an easier way to do this, but you might look at using

system_profiler and some combination of grep and awk to pull what you need. Just playing around quickly I came up with this to pull the displays:

system_profiler | grep -i -B 1 resolution:

Of course, this pulls back a bit more info than you need, but it is a
starting point.

system_profiler can take ages to run depending on the machine/environment

I'd always suggest pulling the section of the profile that you want

system_profiler SPDisplaysDataType | grep -i -B 1 resolution

$ system_profiler SPDisplaysDataType | grep -B 1 Resolution | xargs echo -n | sed -e 's/: Resolution://'

Thanks to all of you for your suggestions,

[sean]

You are assuming only one monitor!

sed -e 's/: Resolution://g'

Would be wiser. At which point you might want to put the newlines back in!!!

sed 's/-- /'$' ''/'

Oops, same problem, that should have read

sed 's/-- /'$' ''/g'

Having just written a script to do a similar job, the main thing I found once finished was that querying SPDisplaysDataType while the machine is at LoginWindow returns nothing!
Just a heads up on that ;-)

I found ScreenUtil met my needs better: http://www.mowlem-enterprises.co.uk/

It's true, depends on how important this EA is.

For items of this nature, you could use launchd to compile a list of items that you want and place them into your own plist and ensure this only runs when someone is logged in.

Your EA then just needs to list the items from your plist.
