Setup with New Relic

This demo is meant to show how to connect your New Relic Observability Platform to a Varnish Enterprise Server.

Set-up a New Relic account

If you don’t already have a New Relic account, sign up for a free account. You will need a license key from your New Relic account, which will be required in later steps.

Configure a Service File and systemd Drop-In

The following step ensures that data is sent to New Relic via the varnish-otel service.

mkdir -p /etc/systemd/system/varnish-otel.service.d
cat << EOF > /etc/systemd/system/varnish-otel.service.d/newrelic.conf
[Service]
Environment=OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.nr-data.net
Environment=OTEL_EXPORTER_OTLP_HEADERS=api-key=<license-key-value>
EOF

Replace <license-key-value> with your INGEST - LICENSE value from New Relic UI > Account > Administration > API Keys.

Make sure to restart the service after applying the configurations:

systemctl daemon-reload
systemctl restart varnish-otel.service

Testing

To test if everything is working, you can send some curl requests to localhost, and the results should appear in the New Relic UI as expected:

# this is only for testing so you can expect a 503 from Varnish

curl localhost:6081/this-is-a-test
