sysstat for Debian
|
|
==================
|
|
|
|
The sar(1) command can display both current statistics (when sar
|
|
is called with interval and count parameters, e.g. `sar 1 10')
|
|
or all-day statistics (when is called without those parameters,
|
|
e.g. just `sar').
|
|
|
|
To display all-day statistics with the sar(1) command, the data must
|
|
have been collected first with sadc(8) or sa1(8) and saved in a file
|
|
in /var/log/sysstat directory.
|
|
This Debian package provides a system crontab file, which runs sa1 script,
|
|
but it is by default DISABLED and the statistics are not collected. Thus when
|
|
you try to run sar without any parameters, you most probably get error like
|
|
`Cannot open /var/log/sysstat/saXX: No such file or directory'.
|
|
|
|
To avoid the error, please enable collecting data by the crontab by running
|
|
dpkg-reconfigure sysstat
|
|
and answering `yes' to the question
|
|
`Do you want to activate sysstat's cron job?'
|
|
|
|
|

|
|
|
|
As it was said above, the package installs system crontab files, namely
|
|
/etc/cron.d/sysstat and /etc/cron.daily/sysstat. There's no need to follow
|
|
the `Examples' section of sa1(8) and sa2(8) man pages and create entries
|
|
in your root crontab file by hand. Creating such entries can lead to a
|
|
situation, where e.g. two copies of sa2(8) script will be run simultaneously,
|
|
which can cause errors.
