Running Minio Prometheus Exporter Slack

This recipe explains how to run a Minio Prometheus exporter.

1. Prerequisites

  • Install Minio Server from here.
  • Get the minio-exporter from here.

2. Running the exporter

Once the Minio server starts there are two ways to run the exporter, via building the binaries or using the docker image.

Run the exporter using the binaries

make
./minio_exporter [flags]
Flag Description Default
version Print version number and leave
web.listen-address The address to listen on to expose metrics. :9290
web.telemetry-path The listening path for metrics. /metrics
minio.server The URL of the minio server. Use HTTPS if Minio accepts secure connections only. http://localhost:9000
minio.access-key The value of the Minio access key. It is required in order to connect to the server ""
minio.access-secret The calue of the Minio access secret. It is required in order to connect to the server ""
minio.bucket-stats Collect statistics about the buckets and files in buckets. It requires more computation, use it carefully in case of large buckets. false 
./minio_exporter -minio.server minio-host.example:9000 -minio.access-key "login_name" -minio.access-secret "login_password"

Running the exporter using docker

docker pull joepll/minio-exporter
docker run -p 9290:9290 joepll/minio-exporter -minio.server "minio.host:9000" -minio.access-key "login_name" -minio.access-secret "login_secret"

The same result can be achieved with Enviroment variables.

  • LISTEN_ADDRESS: is the exporter address, as the option web.listen-address
  • METRIC_PATH: the telemetry path. It corresponds to web.telemetry-path
  • MINIO_URL: the URL of the Minio server, as minio.server
  • MINIO_ACCESS_KEY: the Minio access key (minio.access-key)
  • MINIO_ACCESS_SECRET: the Minio access secret (minio.access-secret)
docker run \
       -p 9290:9290 \
       -e "MINIO_URL=http://host.local:9000" \
       -e "MINIO_ACCESS_KEY=loginname" \
       -e "MINIO_ACCESS_SECRET=password" \
       joepll/minio-exporter
