The line 33 34 /usr/lib/sa/sadc /var/adm/sa/sa`date +%d` 35 36 is executed by the start method for the system/sar:default service, 37 if enabled 38 39 sadc is executed once, such that a special record is written to 40 the daily data file when UNIX restarts. 41 422. The execution of shell script 43 sa1 [t n] 44 causes data collection program to write system activity 45 counters n times at every t-second interval on data file. 46 If t and n are not specified, it writes data once. 47 According to your installation's requirement, enter 48 entries of executing sa1 [t n] in /var/spool/cron/crontabs/sys 49 to collect system activity data. 50 For example, entries 51 52 0 8-17 * * 1-5 su sys -c "/usr/lib/sa/sa1 1200 3 &" and 53 0 18-23 * * 1-5 su sys -c "/usr/lib/sa/sa1 &" 54 55 cause data collection program to be activated at every hour 56 on the hour from 8:00 to 23:00 on weekdays. 57 Moreover, It writes data on data file 3 times at every 20 58 minutes interval from 8:00 to 17:00 and once at other times. 59 603. Shell procedure sa2 will invoke sar command to generate 61 the daily report from the data file. Its usage is 62 63 sa2 [-options] [-s hh:mm] [-e hh:mm] [-i ss] 64 65 where -s and -e specify the report starting and ending times 66 respectively, -i specifies the report data interval in seconds. 67 If they are not specified, all data from the data file are to 68 be reported. -options are report options, see manual page 69 sar.1 for description. 70 71 Make an entry to execute sa2 in /var/spool/cron/crontabs. 72 For instance, entry 73 74 5 18 * * 1-5 su adm -c "/usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 3600 75 -ubd &" 76 77 causes the invocation of sar command at 18:05. It generates 78 the daily report that includes the hourly cpu utilization, 79 buffer usage and disk and tape activities from 8:00 to 18:01. 80
