NodeHog

A simple resource hog utility.

Installation

Local use

npm i -g nodehog

Project use

npm i nodehog

Usage

This program can be used to create scheduled stress tests on a given target. Use cases include testing program performance under max CPU or Memory load, testing recovery from max load, and testing virtual autoscaling features such as the Kubernetes horizontal pod autoscaler.

Parameters

• Type: The type of resource to stress (memory | cpu)
• Lifespan: The length of the stress period in milliseconds
• Deathspan: The length of the relief period in milliseconds
• Iterations: The number of cycles to complete before NodeHog exits (1 cycle = 1 lifespan + 1 deathspan)

CLI

$ nodehog cpu 30000 30000 3
