Cannot open /var/log/sysstat/sa20: No such file or directory

  • 772

I have:

mona@pascal:~$ cat /etc/default/sysstat
#
# Default settings for /etc/init.d/sysstat, /etc/cron.d/sysstat
# and /etc/cron.daily/sysstat files
#

# Should sadc collect system activity informations? Valid values
# are "true" and "false". Please do not put other values, they
# will be overwritten by debconf!
ENABLED="true"

and then:

mona@pascal:~$ sudo sar -d
Cannot open /var/log/sysstat/sa20: No such file or directory
Please check if data collecting is enabled in /etc/default/sysstat

Can you please suggest a fix?

  1. Open /etc/default/sysstat using your favorite file editor and change ENABLED="false" to ENABLED="true"

    vi /etc/default/sysstat
----
# Should sadc collect system activity informations? Valid values
# are "true" and "false". Please do not put other values, they
# will be overwritten by debconf!
ENABLED="true"
----

    Restart sysstat: sudo service sysstat restart

    and now here you are!
