Envoy integration

Install the infrastructure agent

To use the Envoy integration, you need to also install the infrastructure agent on the same host. The infrastructure agent monitors the host itself, while the integration you'll install in the next step extends your monitoring with Envoy-specific data.

Enable the Envoy integration with nri-prometheus

To set up the Envoy integration, follow these steps:

1. Create a file named nri-prometheus-config.yml in the integrations directory:

   bash

   카피

   $
   touch /etc/newrelic-infra/integrations.d/nri-prometheus-config.yml

2. Add the following snippet to your nri-prometheus-config.yml file to enable the agent to capture Envoy data:

   integrations:
     - name: nri-prometheus
       config:
         # When standalone is set to false nri-prometheus requires an infrastructure agent to work and send data. Defaults to true 
         standalone: false
   
         # When running with infrastructure agent emitters will have to include infra-sdk 
         emitters: infra-sdk
   
         # The name of your cluster. It's important to match other New Relic products to relate the data.
         cluster_name: "YOUR_DESIRED_CLUSTER_NAME"
   
         targets:
           - description: Envoy metrics list
             urls: ["http://<ip-address>:9901/stats/prometheus"]
   
         #     tls_config:
         #     ca_file_path: "/etc/etcd/etcd-client-ca.crt"
         #     cert_file_path: "/etc/etcd/etcd-client.crt"
         #      key_file_path: "/etc/etcd/etcd-client.key"
   
         # Whether the integration should run in verbose mode or not. Defaults to false
         verbose: false
   
         # Whether the integration should run in audit mode or not. Defaults to false.
         # Audit mode logs the uncompressed data sent to New Relic. Use this to log all data sent.
         # It does not include verbose mode. This can lead to a high log volume, use with care
         audit: false
   
         # The HTTP client timeout when fetching data from endpoints. Defaults to 30s.
         # scrape_timeout: "30s"
   
         # Length in time to distribute the scraping from the endpoints
         scrape_duration: "5s"
   
         # Number of worker threads used for scraping targets.
         # For large clusters with many (&gt;400) endpoints, slowly increase until scrape
         # time falls between the desired `scrape_duration`.
         # Increasing this value too much will result in huge memory consumption if too
         # many metrics are being scraped.
         # Default: 4
         # worker_threads: 4
   
         # Whether the integration should skip TLS verification or not. Defaults to false
         insecure_skip_verify: true
       timeout: 10s

Forward Envoy logs

Follow these steps to forward Envoy logs to New Relic:

1. Edit the log file named logging.yml located at the following path:

   bash

   카피

   $
   cd /etc/newrelic-infra/logging.d

2. Add the following script to the logging.yml file. Replace file with your Envoy log filepath if needed:

   logs:
     - name: envoy.log
       file: /tmp/envoy.log
       attributes:
         logtype: envoy_logs
     - name: envoy-admin.log
       file: /tmp/admin_access.log
       attributes:
         logtype: envoy_admin_logs

Restart the New Relic infrastructure agent

Restart your infrastructure agent.

$
sudo systemctl restart newrelic-infra.service

In a couple of minutes, your application will send metrics to one.newrelic.com.

Find your data

You can choose our pre-built dashboard template named Envoy to monitor your Envoy application metrics. Follow these steps to use our pre-built dashboard template:

1. From one.newrelic.com, go to the + Integrations & Agents page

2. Click on Dashboards

3. In the search bar, type Envoy

4. The Envoy dashboard should appear. Click on it to install it

   Your Envoy dashboard is considered a custom dashboard and can be found in the Dashboards UI. For docs on using and editing dashboards, see our dashboard docs.

   Here is a NRQL query to check the Envoy downstream total connections:

   SELECT latest(envoy_http_downstream_cx_total) as 'Downstream total connections' from Metric
