Are the vmstat patches you created ready for beta testing? Care to
share them so I can test them out?
I plan on putting out a "release candidate" tomorrow.
There is a beta6-vmstat.patch file on http://www.hswn.dk/beta/
which has the vmstat changes; applies on top of beta-6.
Thanks for providing the patch. I applied it and it built without any errors, but I'm still having problems getting it to work. I did copy over the new hobbitgraph.cfg file after installing & deleted the vmstat.rrd for the linux system in question before restarting.
So, my first question: I was looking at the patch and wasn't sure the array order is correct. (I'm not a programmer by any means, so if I'm wrong just say so).
on RHEL3, vmstat's CPU info columns are in this order:
user -12th
system - 13th
IO wait - 14th
idle - 15th
For example (pardon the line wrap):
-bash-2.05b$ vmstat 2
procs memory swap io system cpu
r b swpd free buff cache si so bi bo in cs us sy wa id
0 1 0 19036 27412 4370032 0 0 214 0 622 649 0 1 50 48
in the patch, you have cpu_idl =14 & cpu_wait=15. Is that backwards? Or am I out of my league (disclaimer: I hardly know anything about C programming).
static vmstat_layout_t vmstat_linux_layout[] = {
{ 0, "cpu_r" },
{ 1, "cpu_b" },
{ -1, "cpu_w" }, /* Not present for 2.4+ kernels, so log as "Undefined" */
{ 2, "mem_swpd" },
{ 3, "mem_free" },
{ 4, "mem_buff" },
{ 5, "mem_cach" },
{ 6, "mem_si" },
{ 7, "mem_so" },
{ 8, "dsk_bi" },
{ 9, "dsk_bo" },
{ 10, "cpu_int" },
{ 11, "cpu_csw" },
{ 12, "cpu_usr" },
{ 13, "cpu_sys" },
{ 14, "cpu_idl" },
{ 15, "cpu_wait" }, /* Requires kernel 2.6, but may not be present */
{ -1, NULL }
};
