Alexander,

Thanks for your reply.

ltop also lets you sort by OSS, so that the OSTs sharing an OSS are all next to 
each other.  Do you find tagging more helpful than that?

It may have sense to keep tagging.

I marked OSS dslustre15 and then switched to OST view.  I have all OSTs on 
marked OSS highlighted:

I was about to say 'we do not use it' yesterday; tracking some issue today.
Thanks, ALex.

Hello,

I am working on updating ltop, the text client within LMT 
(https://github.com/chaos/lmt/wiki).  I am adding support for DNE (multiple 
active MDT's within a single filesystem).

In the interesting of keeping the tool free of cruft, I am asking the community 
about their usage.

Currently, ltop allows for the user to "tag" an OST or an OSS, which causes the 
row(s) for that OSS (or OST's on that OSS) to be underlined so that they stand 
out visually.  Presumably this is so that one can follow an OST as it bounces 
around the table, when the table is sorted by something that changes 
dynamically like CPU usage or lock count.

Does anyone use this feature?  The first few people I polled do not use it, but 
if others use it I will extend it to the MDT's.  If no one uses it, then I'll 
remove it entirely.

Thanks,
