connecting an existing new relic account to a heroku rails app to monitor memory

Question

I have an existing New Relic account and an existing rails app on Heroku. I am successfully sending data from the Heroku app to New Relic. However I want to see the memory footprint per dyno in New Relic.

All the documentation I could find says to install the add-on via Heroku. I do not want it to provision a new account for me, I just want it to link to my current account. How can I do this? If I already have New Relic installed and working and I add the add-on, will it just link to the account it is already configured for?

Answer 1

I work for New Relic. Unfortunately, what you are asking for is not possible. When you install the New Relic add-on for Heroku, it automatically generates a new account with a unique license key and account ID. One of the bonuses of this is that you get Standard subscription for free if you use the add-on.

If you have further account-related questions, however, you're welcome to write to New Relic support to see if you can work something out with your account manager.

Hi lauradiane, do you have any update on this issue as of now ? – Fibro

It's nearly a year later now and I am also wondering whether it's possible to hook an existing heroku app into an existing new relic account? – Darby

if you're still a NR employee, can you update this to say whether @Hefty is correct, or whether this is still not possible with NR? – Secretariat

Answer 2

There is actually a workaround for this issue now. You can simply change NEW_RELIC_LICENSE_KEY env var:

$ heroku config:set NEW_RELIC_LICENSE_KEY='<key_of_your_existing_account>'

You find <key_of_your_existing_account> under Account settings > Summary (right bar with title Account information).

After restarting your app, it will show up on your existing account.

You can even customize additional things like:

$ heroku config:set NEW_RELIC_APP_NAME='<nice_name>' NEW_RELIC_LICENSE_KEY='<key>'

Answer 3

From my testing of Heroku provisioned New Relic accounts and direct ones is that the 'Instances' tab only appears when you are accessing via a Heroku provisioned New Relic - I'm imagine this is because it's a specific setting for the Heroku New Relic account that your application will be in.

Yeah, that is my understanding as well. My question is basically: Is it possible to hook an existing heroku into an existing new relic in the same way? – Whitelaw
