In this article, I’ll show you how to set up monitoring of a Rust web application. The application will expose Prometheus metrics that will be visualized using Grafana. The monitored application is mongodb-redis demo described in detail here. Finally, the following architecture will be obtained:

The project is implemented with MongoDB Rust driver and redis-rs crate.

Prometheus text exposition format is de-facto standard used in monitoring. It would be great building an official observability standard on top it. This format is much easier to debug and understand than OpenTelemetry for metrics. It is also more efficient, e.g. it requires less network bandwidth and less CPU for transfer than Otel for metrics.

I've set up prometheus to monitor kubernetes metrics by following the prometheus documentation.

It was added back to Prometheus.

Exporters are third-party tools that send metrics to the Prometheus server. When Prometheus cannot access metrics, it uses exporters. These exporters export metrics from systems and send the metrics to the Prometheus server. There are official and non-official exporters in Prometheus' GitHub organization.

Now I'm looking for another energy monitor and I'm really struggling to find one! https://github.com/prometheus/docs/blob/main/content/docs/instrumenting/exporters.md

Metrics are exposed in a simple text-based format.
