Check_MK Werk 6735: cpu_util_unix: Fixed calculation of CPU usage on UNIX

ID: 6735 Title: cpu_util_unix: Fixed calculation of CPU usage on UNIX Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 The result of the cpu_usage is wrong. The cpu_time_guest is included in cpu_time_user: See https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/kerne… for more information: <code> /* * Account guest CPU time to a process. * @p: the process that the CPU time gets accounted to * @cputime: the CPU time spent in virtual machine since the last update */ void account_guest_time(struct task_struct *p, u64 cputime) { u64 *cpustat = kcpustat_this_cpu->cpustat; /* Add guest time to process. */ p->utime += cputime; account_group_user_time(p, cputime); p->gtime += cputime; /* Add guest time to cpustat. */ if (task_nice(p) > 0) { cpustat[CPUTIME_NICE] += cputime; cpustat[CPUTIME_GUEST_NICE] += cputime; } else { cpustat[CPUTIME_USER] += cputime; cpustat[CPUTIME_GUEST] += cputime; } } </code>
