Red Hat Bugzilla – Bug 835487
sar -y prints an error message on ppc64

Version-Release number of selected component (if applicable):
Steps to Reproduce:
* get a ppc64 machine with RHEL-7.0 installed
* run following automated test on the machine:
# sar -y
Requested activities not available in file /var/log/sa/sa25
* sar -y produces the same output on all architectures
Sorry, here is the URL where you can see the problem:
please, what's the content of the /proc/tty/driver/serial file?
And what's the output of this command? (needs to be run as root):
# sar -y 1 1
Was that a virtual machine? There may be a problem with some virtual machines, see bug #715300
I've tried RHEL-7.0-20120711.2, ppc64 on ibm-p730-02-lp1.rhts.eng.bos.redhat.com machine.
Content of /proc/tty/driver/serial file is following:
# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:unknown port:00000000 irq:0
1: uart:unknown port:00000000 irq:0
2: uart:unknown port:00000000 irq:0
3: uart:unknown port:00000000 irq:0
what means, that there are no statistics available for sar.
So.. this is not a sysstat bug. But I can't tell whether it is notabug or bug for kernel or something..
I haven't seen the error message for a long time. Maybe it's fixed. Because it seems not to be a sysstat bug we can close it as NOTABUG. If I encounter the error message again, I will report it against kernel and I will add you to CC list.
I agree. Closing as NOTABUG. Thanks.
