Sensu Go Memory Checks

Bonsai Asset Badge TravisCI Build Status

This plugin provides checks for system memory for Sensu Go.

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-memory-checks repository:

sensu-go-memory-checks

go build -o /usr/local/bin/sensu-go-memory-checks 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:

---
type: Asset
api_version: core/v2
metadata:
  name: sensu-go-memory-checks
  namespace: CHANGEME
  labels: {}
  annotations: {}
spec:
  url: https://github.com/asachs01/sensu-go-memory-checks/releases/download/0.0.1/sensu-go-memory-checks_0.0.1_linux_amd64.tar.gz
  sha512: 
  filters:
  - 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)
