Sensu Go CPU Check

This plugin provides a check for system uptime for Sensu Go. The sensu-go-cpu-check check takes the flags -w (warning) and -c (critical) and a desired duration utilization percentage after each flag. By default, these are a warning value of 75% and a critical value of 90%.

Installation

While it's generally recommended to use an asset, you can download a copy of the handler plugin from releases,
or create an executable script from this source.

From the local path of the sensu-go-cpu-check repository:

sensu-go-cpu-check

go build -o /usr/local/bin/sensu-go-cpu-check main.go

Configuration

Asset Registration

Assets are the best way to make use of this check. If you're not using an asset, please consider doing so! You can find this asset on the Bonsai Asset Index.

You can download the asset definition there, or you can do a little bit of copy/pasta and use the one below:

  - entity.system.os == 'linux'
  - entity.system.arch == 'amd64'

NOTE: PLEASE ENSURE YOU UPDATE YOUR URL AND SHA512 BEFORE USING THE ASSET. If you don't, you might just be stuck on a super old version. Don't say I didn't warn you ¯\(ツ)/¯
