Missing metric "Drives Free Inodes" from widget in minio console, as the console widget is using incorrect metric "minio_cluster_drive_free_inodes" which is not exposed in minio.

Expected Behavior

"Drives Free Inodes" widget from the Resource tag should have metric shown up.
Missing metric "Drives Free Inodes" widget should use the metrics "minio_node_drive_free_inodes"

Current Behavior

"Drives Free Inodes" widget shown blank metrics

Possible Solution

Change the metric reference of "minio_cluster_drive_free_inodes" to "minio_node_drive_free_inodes" in

console/api/admin_info.go

Line 778 in 649c3d7

Expr: `minio_cluster_drive_free_inodes{$__query}`,

Steps to Reproduce (for bugs)

  1. Configured console server with external prometheus server source with env CONSOLE_PROMETHEUS_URL and CONSOLE_PROMETHEUS_JOB_ID
  2. Access the console web with log in and navigated to "Administrator" -> "Monitoring" -> "Metrics" -> "Resources" tags
  3. check "Drives Free Inodes" widget that shown no metrics

Context

Tried to integrate external prometheus source for minio console metric page, but noticed the "Drives Free Inodes" not able to show any metrics
