How do I create dashboards for Envoy in Prometheus?

To create dashboards for Envoy in Prometheus, you need to first install and configure Prometheus, then set up Envoy metrics scraping and visualize them using a dashboard tool like Grafana. Here are the key steps involved:

Step 1: Configure Envoy for Prometheus Metrics

Make sure that Envoy is configured to expose metrics in a format that Prometheus can scrape. This can be done by adding the following configuration in your Envoy config file:

static_resources: listeners: - name: listener_0 address: socket_address: { address: 0.0.0.0, port_value: 10000 } filter_chains: - filters: - name: "envoy.filters.network.http_connection_manager" config: codec_type: AUTO stat_prefix: ingress_http route_config: name: local_route virtual_hosts: - name: local_service domains: ["*"] routes: - match: { prefix: "/" } route: { cluster: service_a } http_filters: - name: "envoy.filters.http.router" admin: access_log_path: "/dev/stdout" profile_path: "/dev/stdout" address: socket_address: { address: 127.0.0.1, port_value: 9901 } stats_sinks: - name: "envoy.statsd" config: address: { socket_address: { address: "127.0.0.1", port_value: 8125 }}

Step 2: Configure Prometheus to Scrape Envoy Metrics

Next, you will need to inform Prometheus to scrape the metrics exposed by Envoy. This can be done by adding a scrape configuration to your Prometheus configuration file:

scrape_configs: - job_name: 'envoy' static_configs: - targets: [':9901']

Step 3: Visualizing Metrics in Grafana

Once Prometheus scrapes the metrics, you can create a Grafana dashboard. Connect Grafana to your Prometheus instance and use various charts and panels to visualize Envoy metrics.
