Introduction

Minio can be setup to work with Prometheus by adding the following environment variables to your minio deployment

Minio ENV

        - name: MINIO_PROMETHEUS_AUTH_TYPE
          value: public
        - name: MINIO_PROMETHEUS_URL
          value: http://prometheus.istio-system:9090
        - name: MINIO_PROMETHEUS_JOB_ID
          value: minio-job

Setting MINIO_PROMETHEUS_AUTH_TYPE to 'public' means you can scpae these metrics without the need for a token in your scrape config.

You then need to setup a new job in Prometheus to scrape the Minio metric endpoint

    - job_name: minio-job
      metrics_path: /minio/v2/metrics/cluster
      scheme: http
      static_configs:
      - targets: ['minio.default:9000']

The job_name should match the MINIO_PROMETHEUS_JOB_ID from the previous step.

The metrics will now be available in Prometheus.
