As you said in earlier mail, when I sort by IO rate, locks, etc., selected OST are jumping around or just in different rows as seen below. Anyway, this is not strong desire in the long term: I may feed cerebro output to the web page. Best regards, Alex.

Do you find tagging more helpful than that? Olaf P.

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, Olaf P.
