Stream Logs from Heroku

You can stream your Heroku logs to New Relic using Heroku's built-in Logplex router. Here we explain how to stream logs to New Relic using Heroku syslog drains.

Requirements

Ensure the following before configuring log forwarding from Heroku:

1. Your New Relic user account has the Admin role assigned to it.
2. The account you wish to send logs to has at least one Insights Insert API Key associated with it.

Create a Heroku syslog drain

1. Download and install the Heroku CLI.

2. Use the Heroku CLI to create a syslog drain and attach it to the application you want to stream logs from, replacing YOUR_APP_NAME with the name of your Heroku application.

   $ heroku drains:add syslog+tls://newrelic.syslog.nr-data.net:6515 -a YOUR_APP_NAME

   コピー

3. Run the following command and copy the Heroku syslog drain token from the token attribute:

   $ heroku drains -a YOUR_APP_NAME--json

   コピー

   {
   "addon": null,
   "created_at": "2018-12-04T00:59:46Z",
   "id": "906262a4-e151-45d2-b35a-a2dc0ea9e688",
   "token": "d.f14da5dc-106b-468d-b1bd-bed0ed9fa1e7",
   "updated_at": "2018-12-04T00:59:47Z",
   "url": "syslog://logs.example.com"
   }

   コピー

Register a Heroku syslog drain

Next, you'll need to register your newly created Heroku syslog drain in New Relic:

1. Login to New Relic Logs and click Add more data sources.

   

2. Click the Heroku tile under Log ingestion.

   

3. Choose the New Relic account to stream your Heroku application logs to and click Continue.

4. Paste your newly created Heroku drain token in the Heroku drain token field.

5. Select an Insights insert API key from the drop-down.

6. Click Add Heroku drain log to complete registration.

View log data

Once logs are streaming you can view them using:

• New Relic Logs

• New Relic tools for running NRQL queries. For example, you can execute a query like this:

  SELECT * FROM Log

  コピー

What's next?

Now that you've enabled Logs, here are some potential next steps:

• Explore your data using the Logs UI.
• Configure your agent to see contextual log data, such as distributed tracing, stack traces, application logs, and more.
• Query your data and create custom dashboards or alerts.

If no data appears after you enable log management, follow the troubleshooting procedures.
