The Nginx InfluxDB Module is a custom module for Kubernetes Ingress controllers that enables real-time monitoring of incoming requests using InfluxDB as the backend. The module was created to address the lack of observability features in the official Ingress controller, specifically the ability to track down incoming requests and their status codes. The module acts as a filter on each request, sending processed data to an InfluxDB backend using UDP and line protocol. It can be used with either plain usage or Telegraf as a sidecar proxy configuration. The module's API is currently being stabilized and will be released as version 1.0. The author recommends testing the module in a staging environment before deploying it in production, but notes that they are already using it in their own production environment.
