Envoy is a cloud-native high-performance proxy and a recognized CNCF project.

You can send Envoy metrics to Logz.io using Metricbeat.

Please note that the following configuration needs to be performed on all relevant Envoy client nodes.

Metricbeat setup

Before you begin, you’ll need:

Download the Logz.io public certificate to your Filebeat server

For HTTPS shipping, download the Logz.io public certificate to your certificate authority folder.

sudo curl https://raw.githubusercontent.com/logzio/public-certificates/master/AAACertificateServices.crt --create-dirs -o /etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt
Add Prometheus module configuration

Open the Metricbeat configuration file (<<PATH_TO_METRICBEAT>>/metricbeat.yml) with your preferred text editor.

Copy and paste the code block below, overwriting the previous contents, to replace the general configuration with the following settings:

metricbeat.modules:
- module: prometheus 
  period: 10s
  hosts: ["localhost:19000"]
  metrics_path: /stats
  query:
    format: prometheus
Add Logzio fields

Still in the same configuration file, copy and paste the code block below to set Logzio required fields:

# ===== General =====
fields:
  logzio_codec: json
  token: <<METRICS-SHIPPING-TOKEN>>
fields_under_root: true

Replace <<METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to.
Here’s how to look up your Metrics token.

Set Logz.io as the output

Still in the same configuration file, check if Logz.io is already an output. If not, add it now.

# ===== Outputs =====
output.logstash:
  hosts: ["<<LISTENER-HOST>>:5015"]
    ssl.certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']

Replace <<LISTENER-HOST>> with your region’s listener host (for example, listener.logz.io). For more information on finding your account’s region, see Account region.

One last validation - make sure Logz.io is the only output and appears only once. If the file has other outputs, remove them.

The final file should look like this:

metricbeat.modules:
- module: prometheus 
  period: 10s
  hosts: ["localhost:19000"]
  metrics_path: /stats
  query:
    format: prometheus

fields:
  logzio_codec: json
  token: <<METRICS-SHIPPING-TOKEN>>
fields_under_root: true
ignore_older: 3hr
type: metrics
output.logstash:
  hosts: ["<<LISTENER-HOST>>:5015"]
  ssl.certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']
Start Metricbeat

Start or restart Metricbeat for the changes to take effect.

Open your Envoy dashboard in Logz.io

Give your metrics a few minutes to get from your system to ours, and then open Logz.io.

Your metrics should appear in the preconfigured dashboard in your Metrics account. To open it, search your Logz.io Metrics dashboards for Envoy.
