Grafana Loki, but it's for logs

Grafana, Prometheus, Loki and Promtail

Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate, as it does not index the contents of the logs, but rather a set of labels for each log stream.

Promtail is an agent which ships the contents of local logs to a private Grafana Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.

I am assuming you are already familiar with Grafana and Prometheus

Prerequisites

• Kubernetes Cluster >= v1.23
• Familiarity with Grafana, Prometheus, Loki and Promtail
• ...
• Profit?

Deployment

kubectl apply -k ./deployment

This will deploy the following services in monitoring namespace:

• Grafana - preconfigured with Prometheus and Loki as data sources
• Prometheus
• Loki
• Promtail - preconfigured to push data to Loki

Configuration

Once deployed, access Grafana UI via:

kubectl port-forward -n monitoring svc/grafana 3000:3000

Here is how to guide from Grafana / Loki

Why make or use this?

This is an attempt to demystify the different components of Loki Stack, deploying the full stack can seem overwhelming, breaking it down to smaller composable pieces will hopefully help you better understand each service and its configuration.
