Te aro turuki i nga pou i roto i te Openhift

Tena ra, e nga tangata o Habr!

I tenei ra e hiahia ana ahau ki te korero ki a koe me pehea ta matou hiahia ki te aro turuki i nga pou me etahi atu hinonga e rua i roto i te roopu OpenShift me pehea ta matou mahi.

I te tomokanga i a ratou:

• Huringa tuwhera
• Helm
• Prometheus

Hei mahi me te tono java, he maamaa noa nga mea katoa, he maamaa, he tika ake ranei:

1) Te taapiri ki te build.gradle

 implementation "io.micrometer:micrometer-registry-prometheus"

2) Whakahaerehia te prometheus me te whirihoranga

 - job_name: 'job-name'
    metrics_path: '/actuator/prometheus'
    scrape_interval: 5s
    kubernetes_sd_configs:
    - role: pod
      namespaces:
        names: 
          - 'name'

3) Te taapiri whakaatu ki a Grafana

Ko nga mea katoa he maamaa noa, he ngawari hoki tae noa ki te waa ki te tirotiro i nga turanga e tu tata ana ki to maatau ingoa ingoa (ae, he kino tenei, kaore tetahi e mahi, engari he rereke nga mea ka puta).

Pehea te mahi?

I tua atu i te peera me nga postgres me te prometheus ake, me kotahi ano te hinonga - he kaihoko.

Ko te kaihoko i roto i te ariā waitara he kaihoko e kohi inenga mai i tetahi tono, i tetahi tūmau ranei. Mo te kaikawe postgres, kua tuhia ki roto i te Haere, e mahi ana i runga i te kaupapa o te whakahaere i nga tuhinga SQL i roto i te paataka raraunga katahi ka tango a prometheus i nga hua kua puta. Ma tenei ka taea e koe te whakawhānui ake i nga inenga kua kohia ma te taapiri i a koe ake.

Me whakatakoto penei (hei tauira deployment.yaml, kore-herea):

---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: postgres-exporter
  labels:
    app: {{ .Values.name }}
    monitoring: prometheus
spec:
  serviceName: {{ .Values.name }}
  replicas: 1
  revisionHistoryLimit: 5
  template:
    metadata:
      labels:
        app: postgres-exporter
        monitoring: prometheus
    spec:
      containers:
      - env:
        - name: DATA_SOURCE_URI
          value: postgresdb:5432/pstgr?sslmode=disable
        - name: DATA_SOURCE_USER
          value: postgres
        - name: DATA_SOURCE_PASS
          value: postgres
        resources:
          limits:
            cpu: 100m
            memory: 50Mi
          requests:
            cpu: 100m
            memory: 50Mi
        livenessProbe:
          tcpSocket:
            port: metrics
          initialDelaySeconds: 30
          periodSeconds: 30
        readinessProbe:
          tcpSocket:
            port: metrics
          initialDelaySeconds: 10
          periodSeconds: 30
        image: exporter
        name: postgres-exporter
        ports:
        - containerPort: 9187
          name: metrics

I hiahiatia ano he ratonga me te rerenga whakaahua

Whai muri i te tukunga, ka tino hiahia matou kia kite nga tangata katoa.

Tāpirihia te waahanga e whai ake nei ki te whirihora Prometheus:

  - job_name: 'postgres_exporter'
    metrics_path: '/metrics'
    scrape_interval: 5s
    dns_sd_configs:
    - names:
      - 'postgres-exporter'
      type: 'A'
      port: 9187

Na ka mahi nga mea katoa, ko te toenga ko te taapiri i enei mea katoa ki te grafana ka pai ki te hua.

I tua atu i te kaha ki te taapiri i a koe ake patai, ka taea e koe te whakarereke i nga tautuhinga i roto i te prometheus, me te kohikohi i nga inenga kua whakaritea.

He rite tonu tenei mahi mo:

• Kafka
• Te rangahau elastic
• Mongo

PS Ko nga raraunga katoa mo nga ingoa, nga tauranga me era atu ka tangohia mai i te rangi kaore he korero kei roto.
