Grafana Mimir: Cannot find data in minio pod after enabling remote-write in prometheus

Hi team,
Please advise on my issue with Grafana mimir. I cannot find data in minio pod after enabling remote-write in prometheus

  • What Grafana version and what operating system are you using?
    Rancher Kubernetes cluster with latest Grafana version
  • What are you trying to achieve?
    seeing data in /data in minio pod
  • How are you trying to achieve it?
    I am using Helm to set up Prometheus and Grafana Mimir. My goal is to confirm that Prometheus data appears in the MinIO pod. However, I cannot see any data under the /data folder.

My current settings are:

Prometheus installation:
helm install prometheus prometheus-community/prometheus -n monitoring

  • adding remote write into the configmap of prometheus server:
  prometheus.yml: |
    global:
      evaluation_interval: 1m
      scrape_interval: 1m
      scrape_timeout: 10s
    rule_files:
    - /etc/config/recording_rules.yml
    - /etc/config/alerting_rules.yml
    - /etc/config/rules
    - /etc/config/alerts
    remote_write:
    - url: http://mimir-nginx.mimir-test.svc:80/api/v1/push
    scrape_configs:
    - job_name: prometheus
      static_configs:

Mimir installation:
helm install mimir grafana/mimir-distributed -n monitoring

  • What happened?
    Cannot see the prometheus data in minio pod:
  • Enter minio pod using kubectl exec command
user@DKT:/mnt/c/Users/user$ k exec -it mimir-minio-7ffd96b679-6wb9k -n mimir-test -- sh                                                                          sh-4.4$                                                                                                                                                                               sh-4.4$ cd /data                                                                                                                                                                      sh-4.4$ ls                                                                                                                                                                                                                                                                                                                                                          sh-4.4$ ls -lrt  

I am not sure if I missed anything. I tested prometheus/mimir combo successfully using docker-compose but having issue with the Helm setup in Kubernetes cluster.
Please kindly help. Many thanks.
