Observability Configuration Guide

This document serves as a guide to help you properly set up observability for the Kvrocks in kubernetes.

Prerequisites

Before you proceed, ensure that the Kvrocks operator and kvrocks instances are deployed.

The kvrocks_exporter is set as a sidecar for each pod, as a result, the following should be displayed:

kubectl get pods -n kvrocks
NAME                        READY   STATUS    RESTARTS   AGE
kvrocks-standard-1-demo-0   2/2     Running   0          33s
kvrocks-standard-1-demo-1   2/2     Running   0          33s
kvrocks-standard-1-demo-2   2/2     Running   0          33s

Configuring Prometheus

To scrape the metrics of Kvrocks, you can utilize the configuration below:

 - job_name: 'kvrocks'
      kubernetes_sd_configs:
      - role: pod
      relabel_configs:
      - source_labels: [__meta_kubernetes_pod_name]
        action: keep
        regex: kvrocks-standard-1-demo-.*
      - source_labels: [__meta_kubernetes_pod_container_name]
        action: keep
        regex: kvrocks-exporter
      - source_labels: [__meta_kubernetes_pod_ip]
        regex: (.*)
        target_label: __address__
        replacement: $1:9121
