DESCRIPTION

16       The  sa1  command  is a shell procedure variant of the sadc command and
17       handles all of the flags and parameters of that command. The  sa1  com‐
18       mand collects and stores binary data in the current standard system ac‐
19       tivity daily data file.
20
21       The standard system activity daily  data  file  is  named  saDD  unless
22       sadc's  option  -D is used, in which case its name is saYYYYMMDD, where
23       YYYY stands for the current year, MM for the current month and  DD  for
24       the current day. By default it is located in the /var/log/sa directory.
25
26       The  interval  and  count  parameters specify that the record should be
27       written count times at interval seconds. If no arguments are  given  to
28       sa1 then a single record is written.
29
30       The  sa1  command  is  designed to be started automatically by the cron
31       command.

OPTIONS

35       --boot This option tells sa1 that the sadc  command  should  be  called
36              without specifying the interval and count parameters in order to
37              insert a dummy  record,  marking  the  time  when  the  counters
38              restart from 0.
39
40       --rotate [ iso ]
41              Use  this option to tell sa1 to insert a record of statistics to
42              the standard saDD system activity daily data file of the  previ‐
43              ous  day.   This  should  be done shortly after midnight (on day
44              DD+1) in order to make sure that the data file covers the  whole
45              day,  including  the last interval of time just before midnight.
46              Adding the iso keyword tells sa1 to use  saYYYYMMDD  instead  of
47              saDD as the standard system activity daily data file name.
48
49       --sleep
50              This option tells sa1 that the sadc command should insert a com‐
51              ment indicating that the system is  entering  or  leaving  sleep
52              mode (i.e. system suspend or hibernation).

EXAMPLE

56       To  collect  data  (including those from disks) every 10 minutes, place
57       the following entry in your root crontab file:
58
59       0,10,20,30,40,50 * * * * /usr/lib64/sa/sa1 1 1 -S DISK
60
61       To rotate current system activity daily data file, ensuring it is  com‐
62       plete, place the following entry in your root crontab file:
63
64       0 0 * * * /usr/lib64/sa/sa1 --rotate

68       /var/log/sa/saDD
69       /var/log/sa/saYYYYMMDD
70              The  standard system activity daily data files and their default
71              location.  YYYY stands for the current year, MM for the  current
