I was looking for this myself the other day.
You can get the results you want from ES with the following aggregation:
{
"aggs": {
"hour": {
"terms": {
"script": "doc['@timestamp'].date.hourOfDay"
}
}
}
}
For Kibana, you'd probably need a Histogram panel that is note date based.
That is, you need a custom Kibana panel.
