This summary provides an overview of how Envoy Proxy's PostgreSQL & TCP filters can be used to collect Yugabyte SQL statistics. The process involves installing Docker, creating a configuration file for Envoy, building the containers, and running them in a docker-compose stack. The PostgreSQL filter captures runtime statistics from the database server while remaining transparent to it, providing features such as decoding session information, capturing transaction information, and exposing counters for different types of statements. The TCP filter provides network-level statistics relevant to YSQL, including bytes transmitted and received. The setup allows developers and operations engineers to collect SQL statistics without deploying or managing additional software, making it a convenient integration for YugabyteDB deployments.
