Minio Prometheus Metric

Minio server exposes an endpoint for Promethueus to scrape server data at /minio/metric.

Prometheus probe

Prometheus is used to monitor Minio server information like http request, disk storage, network stats etc.. It uses a config file named prometheus.yaml to scrape data from server. The value for metrics_path and targets need to be configured in the config yaml to specify the endpoint and url as shown:

scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: minio
    metrics_path: /minio/prometheus/metrics

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ['localhost:9000']

Prometheus can be run by executing :

./prometheus --config.file=prometheus.yml
