I've been playing with this off and on for a while in our test environment.

(Yes, I've read the wiki article).

I remember you said we should not need to strip the period out of the value returned from vmstat, because the rrd is storing values in floating point notation.

But -- in do_vmstat.c, you're populating the rrd update vector with this statement : p += sprintf(p, ":%d", values[layout[defidx].index]);

Now I'm NOT a C programmer - but won't that ":%d" format explicitly truncate the value to an integer?

The values I'm talking about are the rightmost two here:

nile:-:/home/kauffmant > vmstat 10 1

System configuration: lcpu=2 mem=8192MB ent=0.10

kthr memory page faults cpu

r b avm fre re pi po fr sr cy in sy cs us sy id wa pc ec 0 0 1080720 394462 0 0 0 0 0 0 28 260 147 2 7 91 0 0.01 10.2

Cpu_pc is 0.01 and cpu_ec is 10.2 -- which means I'm using 10.2 percent of my 0.1 cpu entitlement, for a real cpu count of 0.01.

So, should I plug in the code to strip the decimal point and modify the grapher definitions to divide by 100 and 10, or is there a simpler way out?

TIA
