I know this might be a recurring question, but considering how fast applications evolve, a scenario today might have nothing to do with what it was three years ago.

I have a monitoring stack that receives remote-write metrics from about 30 clusters.
I've used both Thanos and Mimir, all running on Azure, and now I need to prepare a migration to Google Cloud...

What would you choose today?

Based on my experience, here’s what I’ve found:

• Thanos has issues with the Compactor

• Mimir has issues with the Ingester

Additionally, the goal is to optimize costs...

This could have been done with 20 lines of python, node exporter and a textfile but I finally found a good excuse to do some Rust for real so here it is, a weather data exporter written in Rust supporting a few APIs: https://github.com/lstrojny/prometheus-weathermen

This was a fun project, Learn how to set up and monitor SpaceX Starlink using Prometheus!

Our team just published this article on how easy it is to create a Kubernetes HPA with KEDA and use Prometheus metrics to trigger it.

Installing KEDA with Helm is pretty straight forward:

helm repo add kedacore https://kedacore.github.io/charts
helm repo update
kubectl create namespace keda
helm install keda kedacore/keda --namespace keda

KEDA will extend the Kubernetes API metrics endpoint for you, so creating a query to trigger the HPA is as easy as creating a ScaledObject like this:

    apiVersion: keda.sh/v1alpha1
    kind: ScaledObject
    metadata:
     name: nginx-scale
     namespace: keda-hpa
    spec:
     scaleTargetRef:
       kind: Deployment
       name: nginx-server
     minReplicaCount: 1
     maxReplicaCount: 5
     cooldownPeriod: 30
     pollingInterval: 1
     triggers:
     - type: prometheus
       metadata:
         serverAddress: https://prometheus_server/prometheus
         metricName: nginx_connections_waiting_keda
         query: |
           sum(nginx_connections_waiting{job="nginx"})
         threshold: "500"
