Envoy integration for Grafana Cloud
Envoy is an L7 proxy and communication bus designed for large modern service oriented architectures.
This integration includes 1 pre-built dashboard to help monitor and visualize Envoy metrics.
Before you begin
To enable the Prometheus metrics endpoint, you need to activate (Envoy’s admin interface)[https://www.envoyproxy.io/docs/envoy/latest/start/quick-start/admin#admin].
To do so, add the following snippet to your node configuration file:
admin:
address:
socket_address:
address: 0.0.0.0
port_value: 9901
Install Envoy integration for Grafana Cloud
- In your Grafana Cloud stack, click Connections in the left-hand menu.
- Find Envoy and click its tile to open the integration.
- Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Envoy metrics to your Grafana Cloud instance.
- Click Install to add this integration’s pre-built dashboard to your Grafana Cloud instance, and you can start monitoring your Envoy setup.
Post-install configuration for the Envoy integration
Instruct Grafana Agent to scrape your Envoy nodes.
Envoy exposes a /stats/prometheus
endpoint. To scrape it, add the provided snippet to your agent configuration file.
Make sure to change targets
in the snippet according to your environment.
Configuration snippets for Grafana Agent
Below metrics.configs.scrape_configs
, insert the following lines and change the URLs according to your environment:
- job_name: integrations/envoy
metrics_path: /stats/prometheus
static_configs:
- targets: ['localhost:9901']
