if err != nil {
fmt.Println(err)
return
}
// Fetch service status.
st, err := mdmClnt.ServiceStatus()

### New(endpoint string, accessKeyID string, secretAccessKey string, ssl bool) (*AdminClient, error)
Initializes a new admin client object.
__Parameters__
|Param |Type |Description |
|:---|:---| :---|
|`endpoint` | _string_ |Minio endpoint. |
|`accessKeyID` |_string_ | Access key for the object storage endpoint. |
|`secretAccessKey` | _string_ |Secret key for the object storage endpoint. |
|`ssl` | _bool_ | Set this value to 'true' to enable secure (HTTPS) access. |
## 2. Service operations
### ServiceStatus() (ServiceStatusMetadata, error)
Fetch service status, replies disk space used, backend type and total disks offline/online (XL).
| Param | Type | Description |
|---|---|---|
|`serviceStatus` | _ServiceStatusMetadata_ | Represents current server status info in following format: |
| Param | Type | Description |
|---|---|---|
|`st.Total` | _int64_ | Total disk space. |
|`st.Free` | _int64_ | Free disk space. |
|`st.Backend`| _struct{}_ | Represents backend type embedded structure. |
| Param | Type | Description |
|---|---|---|
|`backend.Type` | _BackendType_ | Type of backend used by the server currently only FS or XL. |
|`backend.OnlineDisks`| _int_ | Total number of disks online (only applies to XL backend), is empty for FS. |
|`backend.OfflineDisks` | _int_ | Total number of disks offline (only applies to XL backend), is empty for FS. |
|`backend.ReadQuorum` | _int_ | Current total read quorum threshold before reads will be unavailable, is empty for FS. |
|`backend.WriteQuorum` | _int_ | Current total write quorum threshold before writes will be unavailable, is empty for FS. |
__Example__
```go
st, err := madmClnt.ServiceStatus()
if err != nil {
log.Fatalln(err)
}
log.Printf("%#v\n", st)
```
### ServiceStop() (error)
If successful shuts down the running minio service, for distributed setup stops all remote minio servers.
__Example__
```go
st, err := madmClnt.ServiceStop()
if err != nil {
log.Fatalln(err)
}
log.Printf("Succes")
```
### ServiceRestart() (error)
If successful restarts the running minio service, for distributed setup restarts all remote minio servers.
__Example__
```go
st, err := madmClnt.ServiceRestart()
if err != nil {
log.Fatalln(err)
}
log.Printf("Succes")
```
