Vector: A high-performance observability data pipeline
Datadog bought Timber Technologies (creators of Vector) two years ago. https://www.datadoghq.com/blog/datadog-acquires-timber-techn...
Timber definitely intended to just rock out & demolish everything else out there with their agent/forwarder/aggregator tech. But it wasn't a competitive play against OTel, in my humble opinion. Timber's whole shtick is that it integrates with everything, with really flexible/good glue logic in-between. A competent multi-system (logging, metrics, eventually traces) fluentd++. OTel - I want to believe - would have been part of that original vision.
It's just taking a really really long time. One can speculate how direction & velocity might have changed since the Datadog acquisition. The lack of tracing (anywhere except Datadog, so far) materializing has been a hard hard hard & sad thing to see. OG https://github.com/vectordotdev/vector/issues/1444 and newer https://github.com/vectordotdev/vector/issues/17307
Vector is fantastic software. Currently running a multi-GB/s log pipeline with it. Vector agents as DaemonSets collecting pod and journald logs then forwarding w/ vector's protobuf protocol to a central vector aggregator Deployment with various sinks - s3, gcs/bigquery, loki, prom.
The documentation is great but it can be hard to find examples of common patterns, although it's getting better with time and a growing audience.
My pro-tip has been to prefix your searches with "vector dev A recent contribution added an alternative to prometheus pushgateway that handles counters better: https://github.com/vectordotdev/vector/issues/10304#issuecom...

About reading logs
We don't pull logs, we forward logs to a centralized logging service.
-
Self hosted log paraer
opensearch - amazon fork of Elasticsearch https://opensearch.org/docs/latestif you do this an have distributed log sources you'd use logstash for, bin off logstash and use vector (https://vector.dev/) its better out of the box for SaaS stuff.

Show HN: Homelab Monitoring Setup with Grafana
I think there's nothing currently that combines both logging and metrics into one easy package and visualizes it, but it's also something I would love to have.
Vector[1] would work as the agent, being able to collect both logs and metrics. But the issue would then be storing it. I'm assuming the Elastic Stack might now be able to do both, but it's just to heavy to deal with in a small setup.
A couple of months ago I took a brief look at that when setting up logging for my own homelab (https://pv.wtf/posts/logging-and-the-homelab). Mostly looking at the memory usage to fit it on my synology. Quickwit[2] and Log-Store[3] both come with built in web interfaces that reduce the need for grafana, but neither of them do metrics.

Lightweight logging on RPi?
I would recommend that you run vector as a systems service so you don't have to worry about managing it. Here is a basic config to do that - https://github.com/vectordotdev/vector/blob/master/distribution/systemd/vector.service .

Monitoring traefik access logs easily
You could have a look at Grafana Loki, it's easy to run (single binary for a small setup). Shipping your logs can be done by Promtail or something like Vector. They're both lightweight log shippers with support for Loki.

Kubernetes Ingress Visibility
For the request following, something like jeager https://www.jaegertracing.io/, because you are talking more about tracing than necessarily logging. For just monitoring, https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack would be the starting point, then it depends. Nginx gives metrics out of the box, then you can pull in the dashboard like https://grafana.com/grafana/dashboards/14314-kubernetes-nginx-ingress-controller-nextgen-devops-nirvana/ , or full metal with something like service mesh monitoring which would provably fulfil most of the requirements

Smart-Cash project -Adding monitoring to EKS using Prometheus operator
kube-prometheus-stack is a Helm chart that contains several components to monitor the Kubernetes cluster, along with Grafana dashboards Grafana Dashboards to visualize the data. This option will be used in this article.
- Is Prometheus the right tool for my use case here?
-
Do we have any Prometheus metric to get the kubernetes cluster-level CPU/Memory requests/limits?
We use kube-prometheus-stack for metrics and have added the K8s views dashboards from grafana-dashboards-kubernetes. You should check out the k8s-views-global dashboard. I believe it's just what you are looking for.

Good luck! It's a lot.

How do you set up Grafana alert for your cluster? Which mixins library?
The 2 most common approaches I have seen are kube-prometheus-stack and kube-prometheus..

What are good options for observability for tiny startup?
A basic Prometheus setup is only a helm chart or ansible role away.

Looking for projects ideas for experienced devops engineers
There are integration repos for configuration management like Ansible and Helm Charts that need maintainers/contributors.
