The measures are consolidated to the following metrics - `disk_storage_used` : Disk space used by the disk. - `disk_storage_available`: Available disk space left on the disk. - `disk_storage_total`: Total disk space on the disk. - `disks_offline`: Total number of offline disks in current MinIO instance. - `disks_total`: Total number of disks in current MinIO instance. - `s3_requests_total`: Total number of s3 requests in current MinIO instance. - `s3_errors_total`: Total number of errors in s3 requests in current MinIO instance. - `s3_requests_current`: Total number of active s3 requests in current MinIO instance. - `internode_rx_bytes_total`: Total number of internode bytes received by current MinIO server instance. - `internode_tx_bytes_total`: Total number of bytes sent to the other nodes by current MinIO server instance. - `s3_rx_bytes_total`: Total number of s3 bytes received by current MinIO server instance. - `s3_tx_bytes_total`: Total number of s3 bytes sent by current MinIO server instance. - `minio_version_info`: Current MinIO version with commit-id. - `s3_ttfb_seconds_bucket`: Histogram that holds the latency information of the requests. And this PR also modifies the current StorageInfo queries - Decouples StorageInfo from ServerInfo . - StorageInfo is enhanced to give endpoint information. NOTE: ADMIN API VERSION IS BUMPED UP IN THIS PR Fixes #7873
