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
