GoKawiilCategorica open-sources Prometheus exporter module built into NGINX
Categorica has released an open-source NGINX module that exports Prometheus metrics natively, rather than through a separate exporter process. The module can be compiled directly into NGINX using a supplied Makefile, which also handles fetching the NGINX source code needed for the build.
GoKawiil's interpretation of the reporting above, not reported fact.
The existing standard tool, NGINX Prometheus Exporter, runs as its own web server, often deployed as a sidecar container, which Categorica says adds unnecessary complexity and means the metrics collector itself isn't monitored. A native module could simplify deployments for teams running NGINX and Prometheus together, though adoption will depend on whether it matches the feature coverage of the existing exporter.
- Categorica has open-sourced a Prometheus statistics exporter built as a native NGINX module.
- It aims to replace the standalone NGINX Prometheus Exporter, avoiding sidecar containers and separate web servers for metrics.
- Setup requires compiling NGINX from source with the module, using a provided Makefile and basic command-line familiarity.
