Metric testing for scaling on Kubernetes.

This folder contains tools to aid in measuring the scaling capabilities of Kubernetes clusters.

The tools tend to take one of two forms:

Tools to take measurements
Tools to analyse results

For more details, see individual sub-folders. A brief summary of available tools is below:

Tool	Description
lib	General library helper functions for forming and launching workloads, and storing results in a uniform manner to aid later analysis
scaling	Tests to measure scaling, such as linear or parallel launching of pods
report	Rmarkdown based report generator, used to produce a PDF comparison report of 1 or more sets of results

Results storage and analysis

The tools generate JSON formaated results files via the lib/json.bash functions. The metrics_json_save() function in that file has the ability to also curl or socat the JSON results to a database defined by environment variables (see the file source for details). This method has been used to store results in Elasticsearch and InfluxDB databases for instance, but should be adaptable to use with any REST API that accepts JSON input.
