This plugin provides native CPU instrumentation for monitoring and metrics collection, including CPU usage and metrics for user, nice, system, idle, iowait, irq, softirq, steal, and guest.

metrics-user-pct-usage.rb
check-cpu
Checks CPU usage.
metrics-cpu-interrupts
Provides metrics for CPU interrupts.
metrics-cpu-mpstat
Provides metrics for individual CPU and overall CPU usage.
metrics-cpu-pcnt-usage
Provides metrics for CPU percent usage.
metrics-cpu-softirqs
Provides metrics for CPU softirqs.
metrics-cpu
Provides CPU metrics.
metrics-numastat
Provides a simple wrapper around numastat
for getting per-NUMA-node memory stats.
metrics-softnet-stat
Provides softnet stats.
metrics-user-pct-usage
Produces Graphite output of sum of %CPU over all processes by user. For example, if user Joe is running two processes, each using 10% CPU, and user Jane is running one process using 50% CPU, output will be:
check-cpu.rb
Usage: check-cpu.rb (options)
--cache-file CACHEFILE
-c CRIT
--guest Check cpu guest instead of total cpu usage
--guest_nice Check cpu guest_nice instead of total cpu usage
--idle Check cpu idle instead of total cpu usage
--idle-metrics METRICS Treat the specified metrics as idle. Defaults to idle,iowait,steal,guest,guest_nice
--iowait Check cpu iowait instead of total cpu usage
--irq Check cpu irq instead of total cpu usage
-l, --less_than Change whether value is less than check
--nice Check cpu nice instead of total cpu usage
--proc-path /proc
--sleep SLEEP This sleep controls the interval between the initial poll for cpu utilization and the next data point, the longer the interval is the more accurate your data will be
--softirq Check cpu softirq instead of total cpu usage
--steal Check cpu steal instead of total cpu usage
--system Check cpu system instead of total cpu usage
--user Check cpu user instead of total cpu usage
-w WARN
metrics-numastat.rb
Usage: metrics-numastat.rb (options)
-s, --scheme SCHEME Metric naming scheme, text to prepend to metric
Assets are the best way to make use of this plugin. If you're not using an asset, please consider doing so! If you're using sensuctl 5.13 or later, you can use the following command to add the asset:
sensuctl asset add sensu-plugins/sensu-plugins-cpu-checks
If you're using an earlier version of sensuctl, you can download the asset definition from this project's Bonsai asset index page.
