This is just a space for me to share some notes and thoughts. I hope someone finds something useful here.

I've spent plenty of time configuring it in the past, but lately it just felt like too much work to maintain. Since I try to keep my homelab as low-maintenance as possible, I started looking for something simpler that wouldn't sacrifice the alerting I actually need.</p> <p>I ended up picking <a rel="external" href="https://github.com/robusta-dev/robusta">Robusta</a>. It has a much smaller resource footprint, which is great if you are running on limited hardware. What I like most is that it comes with sensible defaults for things like pod crashes, CrashLoopBackOff, and job failures right out of the box. Email notifications are also a first-class citizen, so I didn't have to spend hours fighting with Alertmanager templates just to get a readable message.</p> <p>Everything is configured as code using Helm values and manifests, so I don't have to touch a UI to keep things running. I am really happy with the switch. If you are looking for a monitoring solution that is easy to set up for a smaller Kubernetes cluster, I definitely recommend giving it a try.</p>
