Actually "sa1" binary is part os "sar" toolkit (sysstat package). It gathers system performance statistics and saves them to binary files /var/log/sa<day number>. Another binary from sar toolkit "sa2" which is run once per day generates (based on /var/log/sa<day number> file) daily system performance report which is then saved in /var/log/sa/sar<day number> file. They're not neccessary for normal system operation and can be disabled (whole sysstat package can be removed) but given the fact that sa1 and sa2 programs are not resource consuming and the fact that sar reports can be quite useful (i suggest storing them) - i would suggest not to disable them. bartek -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
