C means Crashing. That's why it goes up just before the crash. (-:
But seriously, folks, here's the code from ps.c that prints it.
/* "Processor utilisation for scheduling." --- we use %cpu w/o fraction */
static int pr_c(char *restrict const outbuf, const proc_t *restrict const pp){
unsigned long long total_time; /* jiffies used by this process */
unsigned pcpu = 0; /* scaled %cpu, 99 means 99% */
unsigned long long seconds; /* seconds of process life */
total_time = pp->utime + pp->stime;
if(include_dead_children) total_time += (pp->cutime + pp->cstime);
seconds = seconds_since_boot - pp->start_time / Hertz;
if(seconds) pcpu = (total_time * 100ULL / Hertz) / seconds;
if (pcpu > 99U) pcpu = 99U;
return snprintf(outbuf, COLWID, "%2u", pcpu);
}
I read that as percent CPU over the process's lifetime.
