Requirements

  1. Kubernetes cluster with deployed Prometheus and Grafana.
  2. Memcached Exporter deployed alongside with Memcached Pod.

Your Prometheus configuration should contain the following scrape_config:

  1. scrape_configs:
  2.   - job_name: kubernetes-pods
  3.     kubernetes_sd_configs:
  4.       - role: pod
  5.     relabel_configs:
  6.       - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
  7.         action: keep
  8.         regex: true
  9.       - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
  10.         action: replace
  11.         target_label: __metrics_path__
  12.         regex: (.+)
  13.       - source_labels: [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
  14.         action: replace
  15.         regex: ([^:]+)(?::\d+)?;(\d+)
  16.         replacement: $1:$2
  17.         target_label: __address__
  18.       - action: labelmap
  19.         regex: __meta_kubernetes_pod_label_(.+)
  20.       - source_labels: [__meta_kubernetes_namespace]
  21.         action: replace
  22.         target_label: kubernetes_namespace
  23.       - source_labels: [__meta_kubernetes_pod_name]
  24.         action: replace
  25.         target_label: kubernetes_pod_name

Your Memcached Pod should contain prometheus.io/* annotations:

  1. kind: StatefulSet
  2. apiVersion: apps/v1beta1
  3. metadata:
  4.   name: my-memcached
  5. spec:
  6.   serviceName: my-memcached
  7.   replicas: 1
  8.   template:
  9.     metadata:
  10.       annotations:
  11.         prometheus.io/scrape: 'true'
  12.         prometheus.io/port: '9150'
  13.     spec:
  14.       containers:
  15.         - name: memcached
  16.           image: memcached:alpine
  17.           ports:
  18.             - name: memcache
  19.               containerPort: 11211
  20.         - name: metrics
  21.           image: quay.io/prometheus/memcached-exporter:v0.3.0
  22.           ports:
  23.             - name: metrics
  24.               containerPort: 9150
