|
|
|
- **totalcpu** boolean: If true, include `cpu-total` data
|
|
|
|
|
- **percpu** boolean: If true, include data on a per-cpu basis `cpu0, cpu1, etc.`

|
|
|
The CPU plugin collects standard CPU metrics as defined in `man proc`. All
|
|
|
|
|
architectures do not support all of these metrics.

```
|
|
|
|
|
cpu 3357 0 4313 1362393
|
|
|
|
|
The amount of time, measured in units of USER_HZ (1/100ths of a second on
|
|
|
|
|
most architectures, use sysconf(_SC_CLK_TCK) to obtain the right value),
|
|
|
|
|
that the system spent in various states:
|
|
|
|
|
|
|
|
|
|
user (1) Time spent in user mode.
|
|
|
|
|
|
|
|
|
|
nice (2) Time spent in user mode with low priority (nice).
|
|
|
|
|
|
|
|
|
|
system (3) Time spent in system mode.
|
|
|
|
|
|
|
|
|
|
idle (4) Time spent in the idle task. This value should be USER_HZ times
|
|
|
|
|
the second entry in the /proc/uptime pseudo-file.
|
|
|
|
|
|
|
|
|
|
iowait (since Linux 2.5.41)
|
|
|
|
|
(5) Time waiting for I/O to complete.
|
|
|
|
|
|
|
|
|
|
irq (since Linux 2.6.0-test4)
|
|
|
|
|
(6) Time servicing interrupts.
|
|
|
|
|
|
|
|
|
|
softirq (since Linux 2.6.0-test4)
|
|
|
|
|
(7) Time servicing softirqs.
|
|
|
|
|
|
|
|
|
|
steal (since Linux 2.6.11)
|
|
|
|
|
(8) Stolen time, which is the time spent in other operating systems
|
|
|
|
|
when running in a virtualized environment
|
|
|
|
|
|
|
|
|
|
guest (since Linux 2.6.24)
|
|
|
|
|
(9) Time spent running a virtual CPU for guest operating systems
|
|
|
|
|
under the control of the Linux kernel.
|
|
|
|
|
|
|
|
|
|
guest_nice (since Linux 2.6.33)
|
|
|
|
|
(10) Time spent running a niced guest (virtual CPU for guest operating systems under the control of the Linux kernel).
