What is the Envoyproxybeat
Envoyproxybeat is an Elastic Beat that reads stats from the Envoy Proxy and indexes them into Elasticsearch or Logstash.
Configuration Options
You need to adjust the envoyproxybeat.yml configuration file to your needs. Here is a sample configuration:input:
# Defines how often an event is sent to the output
period: 30
# Defines the http port serviced
# Default to :9901
port: :9901
# Defines the http host serviced
# Default to localhost
host: localhost
Options
period

period: 30
envoyproxybeat collect data from the Envoy Proxy the predefined to localhost: 5984. You should be careful when you change these settings.
port: :9901
host: localhost
Run Envoyproxybeat
First, setup Golang environment (if you don't have it already)
cd $GOPATH
mkdir -p src/github.com/berfinsari
cd src/github.com/berfinsari
git clone https://github.com/berfinsari/envoyproxybeat.git
cd envoyproxybeat
make
To run Envoyproxybeat with debugging output enabled, run:
./envoyproxybeat -c envoyproxybeat.yml -e -d "*"
Envoy Proxy Statistics
Envoy outputs numerous statistics which depend on how the server is configured. They can be seen locally via the /stats admin endpoint. The admin endpoint looks directly into the store to load all of the counters and gauges and print them.
Envoyproxybeat reads data from Envoy admin endpoint. For now, Envoyproxybeat collects non-dynamic statistics.
