exploring-rust-ecosystem VS cadvisor

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.

gRPC server

cAdvisor

https://github.com/google/cadvisor exports Prometheus metrics, but also offers a simple web-ui for container metrics.

For CPU and memory metrics, you can use cAdvisor to collect container level data.

Perhaps https://github.com/google/cadvisor + prometheus (or influx or whatever else) + grafana?

We could have used a much more focussed tool like Prometheus or Cadvisor to gather system stats, but that is not the main objective of this article.

Result: Interestingly, the GitHub Issue that talks about cAdvisor and Docker Desktop for Mac for running cAdvisor is still open and not fixed.

If you're running things under systemd, you can enable process accounting and use cAdvisor.
