Subject: sa1: Add --rotate option
X-Git-Tag: v12.5.1~7
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a3ff4079d4cc92f7fc6f7921319d34f3017e6a26;p=sysstat

sa1: Add --rotate option

This option tells sa1 to add a statistics record to the system activity
daily data file of the previous day. This should be done shortly after
midnight in order to make sure that the data file covers the whole day,
including the last interval of time just before midnight.
