### Step 4: Test on Elasticsearch

Upload a JPEG image into `images` bucket.

```
mc cp myphoto.jpg myminio/images
```

Use curl to view contents of `minio_events` index.

```
$ curl  "http://localhost:9200/minio_events/_search?pretty=true"
{
  "took" : 40,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
