Does Grafana provide a Heroku buildpack to send metrics and possibly also logs to Grafana Cloud? If not, has anyone done this before some other way?
Hey @andreas45b1 –
While Grafana Cloud does not currently provide a package or Integration to ship Heroku metrics to Grafana Cloud there are a few different ways to do so yourself (cron job, promtail with Go, HTTP API push…) which others have suggested and are discussed here:

Also a recent Stack Overflow post here might be useful: javascript - How to send logs from a heroku app to grafana cloud? - Stack Overflow
We appreciate the feedback and will keep the interest and feedback on our radar as we work on growing our Integrations library.
- For the logs, you can use Loki: How to easily configure Grafana Loki and Promtail to receive logs from Heroku | Grafana Labs
- And for the metrics, you will need to expose them from your app (e.g.
myapp.com/metrics) and scrap them yourself.
Note: for both of those you will need an extra instance (Promtail to get the logs out and Prometheus Agent to scrap the metrics). I believe Grafana Agent can do both at the same time.
By an extra instance, I mean a Docker Container running somewhere to take the metrics and logs from your Heroku and pass them to Grafana Cloud. They don’t need a database, it’s all handled by Grafana Cloud.
I’m still figuring this out so this may not be the best alternative, but I have made it work for myself.
I use Strapi and conveniently there is a community plugin for exposing the metrics, maybe you can get some inspiration from it: GitHub - XanderD99/strapi-prometheus: Strapi prometheus plugin
