swell

A service for projecting the health of a system onto something where change is easily recognised: art.

Usage

The environment variable PICTURES_URL will have to be set to a URL containing a list of pictures that can be used.

export PICTURES_URL=https://gist.githubusercontent.com/tgk/9562a094037361978c6382bd06d405e1/raw/3ec3872618685a5f1bcd6b07b9ef7b0fe5f91767/gistfile1.txt

We also need to configure a backend by setting MONITOR_MODE to either cloudwatch or http-endpoint. The two modes work as follows:

• http-endpoint mode periodically requests a given HTTP endpoint and inspects the raw text. If the text changes, a different picture is viewed.
• cloudwatch collects all alarms from Cloudwatch and extracts alarm ARN, name, and current state. If any of this information changes a different picture is viewed.

For http-endpoint we also need to specify the endpoint:

export MONITOR_MODE=http-endpoint
export HTTP_ENDPOINT=http://localhost:1234/

For cloudwatch we also need to specify a region

export MONITOR_MODE=cloudwatch
export CLOUDWATCH_AWS_REGION=eu-central-1

lein-env comes with default options which can get you started when in development mode.

That server can be run using the lein plugin

lein ring server 

by building a war and dropping it into a container

lein ring uberwar 

or by calling (user/reset) (in dev environments).
