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 } };
