The sar command here includes two new metrics (pgprom/s et pgdem/s) so that we can now track the number of pages promoted or demoted by the system per second (that is to say, the number of pages migrated from slow to fast, or from fast to slow, memory types). Another metric (%vmeff) has also been removed from sar, as it was more a kernel metric than a system one and it was wrongly calculated with recent kernels. You will also find various small fixes and improvements in this version.
Previous 12.7.3 version (released two days ago) was a Brown Paper Bag release! Current one only fixes a problem that prevented sysstat from being installed. Sorry for that.
This version adds extended reports support to sar. Extended reports,
available using option -x with sar, display minimum and maximum values
in addition to average ones at the end of each report.
This version also includes a lot of fixes and small other improvements.
