Too bad. Do you know if it is so messed up that the apparent order of "uses more" vs. "uses less" would be wrong when the difference in reported figures is fairly large? (I'd avoid assuming an order for sufficiently small differences [which still might be fairly large].) Do you know if the system-wide figures from the summary line: Swap: 61G Total, 61G Free (could also display an in-use figure) are also broken as far as in-use would go? Should top just be avoided for most swap-in-use information? More overall, if anyone knows of such: Is there a place to get reasonable swap-in-use information, per process and/or system-wide? One thing I've wished for is what would be a low bound on the overall maximum-in-use figure (system wide), say by checking periodically a reasonable in-use figure and keeping track of (and reporting) the maximum-observed-so-far figure. This kind of background information could be used in choosing/adjusting a couple of poudriere-devel parameters that control how much parallel activity there can be. (My local top implementation has an adjustment to also display such a system-wide maximum-observed-swap-used figure.) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)Received on Sat Mar 17 2018 - 18:44:32 UTC
