// REF: https://medium.com/codeinsights/how-to-load-test-your-node-js-app-using-k6-74d7339bc787
//
//      brew tap loadimpact/k6
//      brew install k6 grafana influxdb
//      k6 run load_test.js
//      k6 run --out influxdb=http://localhost:8086/resultsdb load_test.js
//
// To have launchd start grafana now and restart at login:
//      brew services start grafana
// Or, if you don't want/need a background service you can just run:
//      grafana-server --config=/usr/local/etc/grafana/grafana.ini --homepath /usr/local/share/grafana cfg:default.paths.logs=/usr/local/var/log/grafana cfg:default.paths.data=/usr/local/var/lib/grafana cfg:default.paths.plugins=/usr/local/var/lib/grafana/plugins
//
// To have launchd start influxdb now and restart at login:
//      brew services start influxdb
// Or, if you don't want/need a background service you can just run:
//      influxd -config /usr/local/etc/influxdb.conf
