the default @timestamp format is UTC format (yyyy-MM-dd'T'HH:mm:ss.SSS'Z'), such as 2018-09-17T08:28:49.883Z , how to set it as GMT format (yyyy-MM-dd HH:mm:ss) ? thank you
My data result example
"_source": {
- "@timestamp": "2018-09-17T08:51:09.927Z",
- "beat": {
- "hostname": "host1",
- "name": "mybeat",
- "version": "5.6.1"},
- "metricset": {
- "module": "system",
- "name": "process",
- "rtt": 72240}
}
