From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt) Description of problem: Every sa2 run generates an error like this: Cannot open /var/log/sa/sa22: No such file or directory Touching the file just changes it to an "invalid" error. Could this be related to the goofy crontabbing of sar in /etc/crontab? How reproducible: Always Steps to Reproduce: 1.Install sysstat 2.Wait for it to run 3.Read the fun and exciting errors in roots mail Actual Results: You are emailed errors as in the description. Note that a few of the days seem to collect data. Here is an ls of /var/log/sa/ from a box that has been up for over a month: -rw-r--r-- 1 root root 191449 Jun 16 23:50 sa16 -rw-r--r-- 1 root root 191449 Jun 17 23:50 sa17 -rw-r--r-- 1 root root 191449 Jun 23 23:50 sa23 -rw-r--r-- 1 root root 191449 Jun 24 23:50 sa24 -rw-rw-rw- 1 root root 186807 Jun 16 19:05 sar16 -rw-rw-rw- 1 root root 186807 Jun 17 19:05 sar17 -rw-rw-rw- 1 root root 0 Jun 18 19:05 sar18 -rw-rw-rw- 1 root root 0 Jun 19 19:05 sar19 -rw-rw-rw- 1 root root 0 Jun 20 19:05 sar20 -rw-rw-rw- 1 root root 0 Jun 21 19:05 sar21 -rw-rw-rw- 1 root root 0 Jun 22 19:05 sar22 -rw-rw-rw- 1 root root 186807 Jun 23 19:05 sar23 Expected Results: The sa files should have data, allowing me to use sar to get performance data. Additional info: Seems to work ok in RHL7.1.
We released sysstat errata for RHL 7.0 that fixed this problem. Or upgrade to 7.1.
