Monitoring Addons

The monitoring addon provides the ability for clients to add monitoring solutions like Grafana, Prometheus, or Alertmanager. This ensure that concerns are accurately identified, reasons are exposed and mainly, that repairs are implemented in a timely manner which improves overall product quality. For a full accounting of monitoring options and how to enable them.

YAML Specifications

YAML

apiVersion: sunpike.platform9.com/v1alpha2
kind: ClusterAddon
metadata:
  labels:
    sunpike.pf9.io/cluster: '<clsuuid>'
    type: monitoring
  name: <clsuuid>-monitoring
  namespace: default
spec:
  clusterID: '<clsuuid>'
  override:
    params:
    # storageClassName and pvcSize are optional params, if storage backend 
    # is not configured the prometheus pod will remain in Pending state
    - name: storageClassName  
      value: default
    - name: pvcSize
      value: "1Gi"
    - name: retentionTime
      value: "7d"
  type: monitoring
  version: 0.46.0
  watch: true

The corresponding Addon object created on the cluster will look similar to this.

YAML

apiVersion: agent.pf9.io/v1
kind: Addon
metadata:
  name: <clsuuid>-monitoring
  namespace: pf9-addons
spec:
  clusterID: <clsuuid>
  type: monitoring
  version: 0.46.0
  watch: true
  override:
    params:
    - name: storageClassName
      value: default
    - name: pvcSize
      value: "1Gi"
    - name: retentionTime
      value: "7d"

Prometheus YAML

When the Prometheus object is deployed by the addon operator, it introduces the following templatized yaml.

YAML

apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  name: system
  namespace: pf9-monitoring
spec:
  image: {{ .QuayRegistry }}/prometheus/prometheus
  additionalScrapeConfigs:
    key: additional-scrape-config.yaml
    name: scrapeconfig
  alerting:
    alertmanagers:
    - name: sys-alertmanager
      namespace: pf9-monitoring
      port: web
  replicas: 1
  resources:
    requests:
      cpu: 500m
      memory: 512Mi
  retention: {{ .retentionTime }}
  ruleSelector:
    matchLabels:
      prometheus: system
      role: alert-rules
  scrapeInterval: 2m
  serviceAccountName: system-prometheus
{{- if .storageClassName }}  
  storage:
    volumeClaimTemplate:
      spec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: {{ .pvcSize }}
        storageClassName: {{ .storageClassName }}
{{- end }}  
  serviceMonitorSelector:
    matchLabels:
      prometheus: system
      role: service-monitor
