Assumptions: a New Relic account and Ubuntu 18. Works on a t2.micro
k6 installation instructions from their docs
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61
echo "deb https://dl.bintray.com/loadimpact/deb stable main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install k6
store our tests in its own directory. organisation is key 🗝
mkdir k6-tests && cd k6-tests
write a sample script and save it as script.js - k6 scripts are written in JavaScript, just like New Relic Synthetics are 😄
echo "import http from 'k6/http'; import { sleep } from 'k6'; export default function() { http.get('http://emea-partners.newrelic-es.com'); sleep(1); }" > script.js
install docker (we need it for running NR StatsD
sudo apt install docker.io -y
run the docker container: include account ID and insert API key
docker run \
-d --restart unless-stopped \
--name newrelic-statsd \
-h $(hostname) \
-e NR_ACCOUNT_ID=<NR ACCOUNT ID> \
-e NR_API_KEY="<YOUR-INSERT-API-KEY>" \
-p 8125:8125/udp \
newrelic/nri-statsd:latest
If your account is in the NR EU region then also add this to the above command: -e NR_EU_REGION=true \
check the container is up and running
sudo docker ps -a
You just include --out statsd to your test run and the metrics will send automatically to NR. You don't need an agent running, that is optional.
k6 run --vus 12 --duration 30s --out statsd script.js
In New Relic you can run NRQL: from Metric select uniques(metricName) where metricName like 'k6%' to view the metrics sent from k6. You can also just discover them in the data explorer.
