What is the Wavefront proxy, and why use it? [Advanced]
Answer
The Wavefront proxy is an ingestion gateway that receives metrics locally and forwards them to Wavefront/DX OpenExplore. I use it to centralize egress, buffer traffic, apply preprocessing rules, normalize tags, and improve reliability.
Technical explanation
A proxy reduces the need for every app or agent to connect directly to the SaaS endpoint.
It can apply point filtering and point alteration rules before data is sent.
In production, multiple proxies behind a load balancer avoid a single point of failure and increase throughput.
Hands-on example
Example: deploy three proxies in Kubernetes, expose them through an internal Service, and point Telegraf and app SDKs to wavefront-proxy.monitoring.svc:2878. Add preprocessor rules to drop dev debug metrics and normalize env tags to prod, stage, or dev.
