Michael,
I believe the system is aware of what it's running, here's some
additional information. Nmon reports it incorrectly as being a Power4.
[EMAIL PROTECTED]:/ # odmget -q name=proc0 CuAt
CuAt:
name = "proc0"
attribute = "type"
value = "PowerPC_POWER5"
type = "R"
generic = "D"
rep = "sl"
nls_index = 49
CuAt:
name = "proc0"
attribute = "frequency"
value = "1902096000"
type = "R"
generic = "D"
rep = "s"
nls_index = 69
CuAt:
name = "proc0"
attribute = "smt_threads"
value = "2"
type = "R"
generic = "D"
rep = ""
nls_index = 82
CuAt:
name = "proc0"
attribute = "smt_enabled"
value = "true"
type = "R"
generic = "D"
rep = ""
nls_index = 83

Subject: Re: [Ganglia-general] cpu_in_lpar Metric Calculation
Hi Bernard,
the code to determie machine_type is actually
g_val_t
machine_type_func( void )
{
g_val_t val;
perfstat_cpu_total_t c;
if (perfstat_cpu_total( NULL, &c, sizeof( perfstat_cpu_total_t ), 1 ) == -1)
strcpy( val.str, "Unknown type" );
else
strncpy( val.str, c.description, MAX_G_STRING_SIZE );
return( val );
}
and that should be read every time. From the man page of perfstat_cpu_total:
The perfstat_cpu_total subroutine retrieves information from the ODM database.
This information is
automatically cached into a dictionary which is assumed to be frozen once
loaded. The perfstat_reset
subroutine must be called to flush the dictionary whenever the machine
configuration has changed.
What does nmon say, does it produce the correct value ?
What is the output of "odmget -q "name=proc0" CuAt" ?
Regards,
Michael

Incorrect fields:
machine_type (still lists PowerPC_POWER4 on a P5 system)
I vaguely remember something about Ganglia reporting the arch of the
system which it was built on -- is it possible that the binaries were
built on a PowerPC_POWER4 system and not P5 system?
Cheers,
Bernard
