[rhelv6-list] sar

Tue Mar 4 20:12:18 UTC 2014

Hi Bill,

   what I think is happening is that the files /var/log/sa/sadd and
/var/log/sa/sardd are being appended. If you have a fresh system, you
won't have any old files in /var/log/sa/

ll /var/log/sa/sa??

Curiously, I don't find this 'feature' within the 6.5 system I just
created last week. Are there any settings you'd like to compare? My
report shows the hours AM then PM then changes to the next category.

Hi Andy,

  if it's not just our systems I'll log a BugZilla report. In a month I
suspect sar will show data for 3 days!

thanks

Iain, 

I am seeing the same on all of my systems.  There is not a log rotate
issue since the appropriate files are created each day.  However, a sar
report runs through the hours twice.

Dear List,

  since 1st March 2014 sar has been behaving oddly on all our RHEL 6.5
systems

The files /var/log/sa/sad and /var/log/sa/sardd are twice as big as
normal and sar reports on two days' worth of data.

It looks like the sa/sar files are being appended rather than
overwritten. Is anyone else seeing this?

thanks

iain
