Sample handler:
```go
    handler :=  func(payload []byte) ([]byte, *grid.RemoteErr) {
        // Do something with payload
        return []byte("response"), nil
    }

    err := manager.RegisterSingleHandler(grid.HandlerDiskInfo, handler)
```

Sample call:
```go
    // Get a connection to the remote host

- MinIO exports Prometheus compatible data by default which is resource centric as an authorized endpoint at `/minio/v2/metrics/resource`.

All of these can be accessed via Prometheus dashboard. A sample list of exposed metrics along with their definition is available on our public demo server at

```sh
curl https://play.min.io/minio/v2/metrics/cluster
```

### List of metrics reported Cluster and Bucket level

Following is a sample directory structure for MinIO server with TLS certificates.

```sh
$ mc tree --files ~/.minio
/home/user1/.minio
└─ certs
   ├─ CAs
   ├─ private.key
   └─ public.crt
```

MinIO protects data against hardware failures and silent data corruption using erasure code and checksums. With the highest level of redundancy, you may lose up to half (N/2) of the total drives and still be able to recover the data.

## What is Erasure Code?

```
KEY:
notify_postgres[:name]  publish bucket notifications to Postgres databases

ARGS:
connection_string*   (string)             Postgres server connection-string e.g. "host=localhost port=5432 dbname=minio_events user=postgres password=password sslmode=disable"
table*               (string)             DB table name to store/update events, table is auto-created

- Follow the on screen wizard

- On the Capacity Tier screen, check the box to Extend scale-out backup repository capacity with object storage checkbox and select the object storage. If you want to be able to test backup data immediately after a job is run, under the object storage selection, check the "Copy" box and uncheck the "Move" box.

### Create a backup job

## **4. Run Sample Applications**

export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
minio server /mnt/data
```

### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.

depending on whether delete replication rules are set up or if object locking is disabled on `destbucket`. The above policies assume that replication of objects, tags and delete marker replication are all enabled on object lock enabled buckets. A sample script to setup replication is provided [here](https://github.com/minio/minio/blob/master/docs/bucket/replication/setup_replication.sh)

To set up replication from a source bucket `srcbucket` on myminio cluster to a bucket `destbucket` on...

```sh
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
./minio server /data
```
