/etc/cron.d/sysstat中

# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib64/sa/sa1 1 1

改为：

# run system activity accounting tool every 10 minutes
*/1 * * * * root /usr/lib64/sa/sa1 1 1

保存就可以了。



查询某天的sar信息可以使用命令


sar -f 文件名
如:sar -f /var/log/sa/sa21


AIX下设置sar作业

# Collect measurements at 10-minute intervals
0,10,20,30,40,50   * * * *   /usr/lib/sa/sa1
# Create daily reports and purge old files
0                  0 * * *   /usr/lib/sa/sa2 -A

备份crontab
crontab -l > /home/oracle/crontab_bak


HP UX

mkdir /var/adm/sa

0,10,20,30,40,50   * * * *   /usr/lib/sa/sa1
