Envoy Proxy


Collecting traffic from real environments is in Beta.

Join the Beta and help chart the course for how Optic works in real environments. We'll work closely with your team to set up Optic to monitor your APIs as they are running in staging, development, or even production environments.

Optic integrates with Envoy as a HTTP filter.

  1. We'll provide you the latest beta plugin release to download.

  2. Add Optic as a HTTP filter in your envoy.yaml and update the lines setting the Optic Token, Source ID and Source Tags.

    http_filters:- name: envoy.filters.http.lua  typed_config:    "@type":    inline_code: |      local optic = require("optic-envoy")
          optic.set_optic_token("Your Optic Token")      optic.set_source_id("A unique identifier for this source of data")      optic.set_optic_token("A comma separated list of other labels to send to Optic")
          function envoy_on_request(request_handle)        optic.process_request(request_handle)      end
          function envoy_on_response(response_handle)        optic.process_response(response_handle)      end
  3. Add the Optic API in a clusters config:

    clusters:  - name: optic-api  connect_timeout: 0.25s  type: logical_dns  http2_protocol_options: {}  lb_policy: round_robin  load_assignment:    cluster_name: optic-api    endpoints:    - lb_endpoints:    - endpoint:      address:        socket_address:        address:        port_value: 443  transport_socket:    name: envoy.transport_sockets.tls    typed_config:    "@type":    sni:    common_tls_context:       validation_context:      match_subject_alt_names:      - exact: ""      trusted_ca:        filename: /etc/ssl/certs/ca-certificates.crt
  4. Restart Envoy.
