Show HN: StatLite – Lightweight dashboard for application monitoring (pvrlabs.xyz)

1 points by ejboy ↗ HN
Single Go binary (~15 MB RAM), compact SQLite-based storage with configurable retention. Ideal for self-hosted app monitoring. No Prometheus/Grafana stack required.

Shows app and DB health, charts for latency, http status codes, native support for Micrometer-based frameworks like Spring Boot/Micronaut/Quarkus. Simple app integration recipes for Django, Express, FastAPI, Go/Gin and others.

Live demo: https://pvrlabs.xyz/statlite/demo.html

Hey man, This thing is legit and will definitely be giving it a go but just out of curiosity have you tried running it on a Raspberry Pi to see how well it performs?

Great question. Low resource usage is one of my primary goals. https://github.com/PVRLabs/statlite/blob/main/docs/low-resou...

Let me know what kind of config you are interested in and I will try to run an experiment on it. I stress test StatLite in different environments, including 256MiB Alpine VPS with a Spring Boot Java app. No OOM crashes there.

Oh very dope because StatLite was the exact one I was interested in! I also figured out some dets, so I have 3 Pi's 4 Model B - 8 GB and then another Pi that is 1st gen so its ehh. Anyways, I figured with your project I could probably merge them into a cluster/database and am considering the weak link Pi serve as just a FastAPI only and the other 3 handle these - Automation: Flux CD, OpenTofu, Ansible, Cloud-init | Certs & Secrets: Cert-Manager, External Secrets, Vault | Auth: Keycloak | Storage: Longhorn

I was thinking about using StatLite to monitor just how poorly the weak Pi affects the overall workflow of the other ones to try and figure out an optimal position for it.

Yeah, that's a great test case. I am planning my own follow-up to emulate Pi using virtualization and maybe use it for CI. Feel free to follow up on GitHub discussions if you run into issues with StatLite on Pi. I would be glad to help.
