Heroku 🔗
The Splunk OpenTelemetry Connector for Heroku is a buildpack for the Splunk Distribution of the OpenTelemetry Collector. The buildpack installs and runs the Splunk OpenTelemetry Connector on a Dyno to receive, process and export metric and trace data for Splunk Observability Cloud:
Splunk APM through the
otlphttpexporter.Splunk Infrastructure Monitoring through the
signalfxexporter.
See Get started with the Splunk Distribution of the OpenTelemetry Collector to learn more.
Prerequisites 🔗
Before you can install the Heroku buildpack to collect metrics, you need to have a Heroku app. To learn how to install the Heroku CLI and create an app, see the Heroku documentation for developers.
Installation steps 🔗

In the command-line interface, navigate to the Heroku project directory.
cd <HEROKU_APP_DIRECTORY>
Note: Running
herokucommand outside of project directories results in unexpected behavior.Configure the Heroku app to expose Dyno metadata, which is required by Splunk OpenTelemetry Connector to set global dimensions such as
app_name,app_idanddyno_id. See here for more information.heroku labs:enable runtime-dyno-metadata
Run both of the following commands together to add the Heroku buildpack.
heroku buildpacks:add https://github.com/signalfx/splunk-otel-collector-heroku.git#\ $(curl -s https://api.github.com/repos/signalfx/splunk-otel-collector-heroku/releases | grep '"tag_name"' | head -n 1 | cut -d'"' -f4)
Note: If you want to use an explict version number for production environment, replace the first command with the following command:
heroku buildpacks:add https://github.com/signalfx/splunk-otel-collector-heroku.git#<TAG_NAME>
Set the required environment variables.
heroku config:set SPLUNK_ACCESS_TOKEN=<YOUR_ACCESS_TOKEN> heroku config:set SPLUNK_REALM=<YOUR_REALM>
