Are you aware of?:

# sar -d -f sa30

Also, you should give a look to collectl:

>>> Requested activities not available in file

This error message means that you are trying to extract non-existent activities from the data file. Usually sadc reads all the available activities from the system and stores them in the data file. However, to prevent data files from taking too much space on disk, some activities must be explicitly set on the command line to be read by sadc. One example is -I option which must be used together with sadc to be able to extract statistics for individual interrupts from the data file. Another example is -d option for disks statistics.


Plese check the man pages for sadc to see if the -d option should be enabled. If so, then verify the sa1 script or you sysstat cron job. You can check the location of the scripts using:

rpm -ql sysstat

then Is there any way to check last week disk utilisation?

[Ivan Ferreira]

Not right now, untill you modify your script and log disk activities.

>>> Please let me know any other way can I get the same details

As I said in a previous post, collectl can provide you that information.

>>> Please let me know what need to be changed in the script also.

Please attach in a file the content of:

/etc/cron.d/sysstat
/etc/sysconfig/sysstat
/usr/lib/sa/sa1
/usr/lib/sa/sa2
/usr/lib/sa/sadc -h
