Имя (Name)
sa1 - Collect and store binary data in the system activity daily
data file.
Синопсис (Synopsis)
/usr/local/lib64/sa/sa1 [ --boot | --rotate [ iso ] | --sleep |
interval count ]
Описание (Description)
The sa1 command is a shell procedure variant of the sadc command
and handles all of the flags and parameters of that command. The
sa1 command collects and stores binary data in the current
standard system activity daily data file.
The standard system activity daily data file is named saDD unless
sadc's option -D is used, in which case its name is saYYYYMMDD,
where YYYY stands for the current year, MM for the current month
and DD for the current day. By default it is located in the
/var/log/sa directory.
The interval and count parameters specify that the record should
be written count times at interval seconds. If no arguments are
given to sa1 then a single record is written.
The sa1 command is designed to be started automatically by the
cron command.
Параметры (Options)
--boot This option tells sa1 that the sadc command should be
called without specifying the interval and count
parameters in order to insert a dummy record, marking the
time when the counters restart from 0.
--rotate [ iso ]
Use this option to tell sa1 to insert a record of
statistics to the standard saDD system activity daily data
file of the previous day. This should be done shortly
after midnight (on day DD+1) in order to make sure that
the data file covers the whole day, including the last
interval of time just before midnight. Adding the iso
keyword tells sa1 to use saYYYYMMDD instead of saDD as the
standard system activity daily data file name.
--sleep
This option tells sa1 that the sadc command should insert
a comment indicating that the system is entering or
leaving sleep mode (i.e. system suspend or hibernation).
