Some of the values at the bottom of putty seem pretty clear to me.

Is there a legend some place that shows what each of these values means?

I suspect this is a feature of bash rather than putty, but I'm not positive.

Update 1: This may be an ubuntu only feature

Update 2: This is byobu

Is there a legend available, or some place that explains this various color coded regions for byobu?

This is neither putty or standard bash. This appears to be a custom bash prompt, possibly a default in Ubuntu. –  Arrowmaster Nov 23 '11 at 18:50
    
Thanks. Updated question to be a bit more relevant –  George W Bush Nov 23 '11 at 19:07

This is Byobu/GNU Screen not a default in Ubuntu. It's a terminal multi-plexor. –  Marco Ceppi Nov 23 '11 at 19:09
    
This is byobu - an interface for screen that gives you various system information around a terminal. –  Oli Nov 23 '11 at 19:10
    
@marco I fired up the default ubuntu AMI for EC2 and my initial connection via putty showed this info. I only mention this, because it may now be a default –  George W Bush Nov 23 '11 at 19:22

From the byobu documentation:

See: Status Notifications

Here's a few samples from the documentation:

cpu_count - the number of cpu's or cores on the system; displayed in the lower bar toward the right in the default text color on the default background, followed by a trailing 'x'

cpu_freq - the current frequency of the cpu in GHz; displayed in the lower bar toward the right in white text on a light blue background

disk_io - instantaneous read/write througput in kB/s or MB/s over the last 3 seconds; displayed in the lower bar toward the right in white text on a light purple background with a leading '<' sign indicating 'read speed' and '>' sign indicating 'write speed'; override the default monitored disk by specifying an alternate device with MONITORED_DISK=/dev/sdb, and override the default DISK_IO_THRESHOLD=50 (kB/s) in $BYOBU_CONFIG_DIR/statusrc

As the maintainer of Byobu and the author of the documentation quoted above, I would VERY much prefer if StackExchange LINKED to the manpage, rather than snapshotting and duplicating it here. I have licensed the documentation you quote above with the GPLv3, and NOT the CC-WIKI license that StackExchange operates under. –  Dustin Kirkland Feb 18 '12 at 22:50
    
@DustinKirkland Technically it did both, which seems ideal -- we encourage users to not just link to other pages in their answers, in case those pages go down and the answer becomes useless. In any case, I removed the duplicated text –  Michael Mrozek Feb 18 '12 at 23:12
    
That kinda works, but your man page will 404 eventually. Links are not future proof. It is necessary to snapshot bits and pieces. I can see your point that I snapshotted too much, but Michael's edit took out WAY too much. –  George W Bush Feb 19 '12 at 2:24
    
The better link to use, from my perspective, is manpg.es/byobu.1, which is a shortened url and always will point to the latest version. –  Dustin Kirkland Feb 19 '12 at 2:39

@hamlin11, your answer is a good one, and I +1'd it. I'm sorry if my comment came down too hard, but I really hope to avoid duplicating the content of manpages in StackExchange. I am asking more and more Byobu user to ask their questions here. But so many of them are clearly answered in the manpages :-( –  Dustin Kirkland Feb 19 '12 at 2:42
