MinIO integration for Grafana Cloud
MinIO is a Kubernetes-native high-performance object storage server which is designed for large-scale private cloud infrastructure and compatible with Amazon S3.
This integration includes 2 useful alerts and 1 pre-built dashboard to help monitor and visualize MinIO metrics.
Before you begin
By default, the agent configuration expects the MINIO_PROMETHEUS_AUTH_TYPE to be set to ‘public’.
If you choose not to set this flag you will need to generate a bearer_token with mc admin prometheus generate <alias> command to generate the scrape config compatible with Grafana agent. To learn more, see monitoring minio docs.
Install MinIO integration for Grafana Cloud
- In your Grafana Cloud stack, click Connections in the left-hand menu.
- Find MinIO and click its tile to open the integration.
- Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send MinIO metrics to your Grafana Cloud instance.
- Click Install to add this integration’s pre-built dashboard and alerts to your Grafana Cloud instance, and you can start monitoring your MinIO setup.
Post-install configuration for the MinIO integration
This integration uses MinIO metrics exposed at /minio/prometheus/metrics endpoint. To scrape it, add the provided snippet to your agent configuration file.
Make sure to change targets in the snippet according to your environment.
Configuration snippets for Grafana Agent
Below metrics.configs.scrape_configs, insert the following lines and change the URLs according to your environment:
- job_name: 'integrations/minio'
metrics_path: /minio/prometheus/metrics
relabel_configs:
- replacement: '<your-instance-name>'
target_label: instance
static_configs:
- targets: ['localhost:9000']Full example configuration for Grafana Agent
Refer to the following Grafana Agent configuration for a complete example that contains all the snippets used for the MinIO integration. This example also includes metrics that are sent to monitor your Grafana Agent instance.

Changelog
# 0.0.6 - September 2023
* New Filter Metrics option for configuring the Grafana Agent, which saves on metrics cost by dropping any metric not used by this integration. Beware that anything custom built using metrics that are not on the snippet will stop working.
* New hostname relabel option, which applies the instance name you write on the text box to the Grafana Agent configuration snippets, making it easier and less error prone to configure this mandatory label.
# 0.0.5 - May 2023
* Fix query in 'Storage Used' panel
# 0.0.4 - December 2022
* Update mixin to latest
- Add instance selector
* Add screenshot
# 0.0.3 - September 2022
* Update dashboard panels descriptions.
# 0.0.2 - October 2021
* Update mixin to latest version:
- Update queries to use $__rate_interval
# 0.0.1 - November 2020
* Initial releaseCost
By connecting your MinIO instance to Grafana Cloud, you might incur charges. To view information on the number of active series that your Grafana Cloud account uses for metrics included in each Cloud tier, see Active series and dpm usage and Cloud tier pricing.
