kern.cp_time
kern.cp_time
Plugin: freebsd.plugin Module: kern.cp_time
Overview
Total CPU utilization
The plugin calls sysctl function to collect necessary data.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
Default Behavior
Auto-Detection
This integration doesn’t support auto-detection.
Limits
The default configuration for this integration does not impose any limits on data collection.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
No action required.
Configuration
File
The configuration file name for this integration is netdata.conf.
The file format is a modified INI syntax. The general structure is:
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf
Options
The netdata main configuration file.
| Name | Description | Default | Required |
|---|---|---|---|
| kern.cp_time | Enable or disable Total CPU usage. | yes | no |
Examples
There are no configuration examples.
Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per kern.cp_time instance
These metrics show CPU usage statistics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| system.cpu | nice, system, user, interrupt, idle | percentage |
Per core
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| cpu.cpu | nice, system, user, interrupt, idle | percentage |
Alerts
The following alerts are available:
| Alert name | On metric | Description |
|---|---|---|
| 10min_cpu_usage | system.cpu | average CPU utilization over the last 10 minutes (excluding iowait, nice and steal) |
| 10min_cpu_iowait | system.cpu | average CPU iowait time over the last 10 minutes |
| 20min_steal_cpu | system.cpu | average CPU steal time over the last 20 minutes |
| 10min_cpu_usage | system.cpu | average CPU utilization over the last 10 minutes (excluding nice) |
