Meet Elephantshark, the tool to monitor PostgreSQL network traffic. It offers a live view of what’s happening on the wire, built on top of simple Postgres proxy scripts in Ruby [1].
What Elephantshark is Elephantshark monitors Postgres network traffic. It builds on top of some simple Postgres proxy scripts in Ruby the author has used for a while [1]. The project’s GitHub page and its AMA signal a hands-on, self-service approach with a README that aims to be self-explanatory [2].
What the AMA signals OP and tool author here: AMA (though I hope the README is pretty self-explanatory) [2].
Why observability matters for operators • Network visibility helps you understand traffic patterns and bottlenecks on Postgres [1]. • A Ruby-based proxy-script foundation suggests a lightweight, DIY approach to monitoring at the edge [1]. • The AMA indicates ongoing community discussion around how to use the tool and what it means for PostgreSQL observability practices [2].
Closing thought Observability tools like Elephantshark push operators to think about what data to surface, how to balance overhead with insight, and how network visibility fits into PostgreSQL tuning and security considerations.
