How to get disk_storage_available by Java sdk

[Andy6Loda]

Is your feature request related to a problem? Please describe.

1. Can i set bucket_storage_total like mc-client 'mc admin bucket quota'
2. Can i get those value(disk_storage_total, ..._used, ..._available) by Java-SDK or AWS-S3, without prometheu?
   3 The mc-client "admin info" just get the disk_storage_tota, but i also need those of every bucket

Describe the solution you'd like

Additional context
1.mc admin --json info

{
    "status": "success",
    "info": {
        "mode": "online",
        "deploymentID": "19c23ac1-a243-4d1c-8add-1f8ffe692b97",
        "buckets": {
            "count": 5
        },
        "objects": {
            "count": 28
        },
        "usage": {
            "size": 4913656
        },

2、quota set

[root@test minio]# ./mc admin bucket quota test/dxnout --hard 2GB
Successfully set bucket quota of 1.9 GiB with hard type on `dxnout`
[root@test minio]# ./mc admin bucket quota test/dxnout --hard 2GiB

OKey，Show myself:

CopyObjectHandler  + PutObjectHandler + CopyObjectPartHandler + PutObjectPartHandler
↓
enforceBucketQuota
↓
globalBucketQuotaSys.check(){
//1
sys.Get(bucket) 
//2
sys.bucketStorageCache.Get()
↓
dui.BucketsUsage[bucket]
↓
if (bui.Size + uint64(size)) >= q.Quota {
			return BucketQuotaExceeded{Bucket: bucket}
		}
}

Another way : measure

curl --location --request GET 'http://*****/minio/prometheus/metrics'
--header 'Authorization: Bearer eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJleHAiOjQ3NjQyNzc2OTIsImlzcyI6InByb21ldGhldXMiLCJzdWIiOiJtaW5pb2FkbWluIn0.jLivGZSo9h8nhDrTtrYaoXUw5uWShDzBsY4Mk3iMI0WCHmaZq0hsxpN4UpD0Yc9zXRKhP2KkHfBPoSiYQ7wRMg'

return: bucket_usage_size{bucket="xxx"} 815990
