Hmm, browsing through the code I found the following
void
update_ifdata( void )
{
...
static double last_time = 0.0; <-- (1)
double now, delta_t;
struct timeval timeValue;
struct timezone timeZone;
gettimeofday( &timeValue, &timeZone );
now = (double) (timeValue.tv_sec - boottime) + (timeValue.tv_usec /
1000000.0);
delta_t = now - last_time; <-- will delta_t not always be equal to now
since last_time is reset everytime (1) ??
...
last_time = now;
}
Met vriendelijke groet
Best regards
Bien à vous

Onderwerp: [Ganglia-general] POWER5 Network Throughput
Hi all
I am using Michael's POWER5/6 aware Ganglia but I do have a question regarding
the network throughput.
For a certain LPARS, topas states peaks up to 210K KBPS,meaning at about 200
Mbytes per sec.
Nevertheless, the bytes_out chart of the LPAR shows only a maximum of 100
Mbytes per sec for that moment.
Is this a bug in libperfstat? (I am using 5300-05-05 on that LPAR).
Tia once again
Met vriendelijke groet
Best regards
Bien à vous
