This appears to be an issue with Mr. Perzl's updated libperfstat code
borrowed from IBM's perfstat_cpu_total example.
ftp://www.oss4aix.org/ganglia/RPMs-3.3.7/src/ganglia-3.3.7-aix.patch
http://publib.boulder.ibm.com/infocenter/aix/v6r1/topic/com.ibm.aix.prftools
Environment:
AIX 6.1 TL7 SP7
gmond 3.6.0 (from http://www.perzl.org/ganglia/)
I noticed that a particular node would send insanely high negative values
for cpu_idle and cpu_wait metrics when cpu_user + cpu_system were near 100%,
i.e. the node is completely CPU bound. The result is major
Here is another example from gstat:
CPUs (Procs/Total) [ 1, 5, 15min] [ User, Nice, System, Idle,
Wio]
8 (8/ 122) [ 4.59, 2.04, 1.35] [ 99.8, 0.0,
0.2,-67062349824.0,-67062349824.0] OFF
Looking at the source code for AIX metrics
