filter {
           match => [
     date {
		match => [ "TimeStamp", "ISO8601" ]
		target => "timestamp"
		timezone => "Asia/Shanghai"


i input [2018-04-13 15:00:00.000]

Do you really need to keep the TimeStamp field that it's complaining about? If you remove it this problem will go away.

so if i add a new date field i need remove original field?

No, you can have as many date fields as you like. But ES apparently doesn't recognize "2018-04-13 15:00
:00.000" as a date. If you want to store it in a field you have to make sure it's a string field.

but when i changed TimeStamp it become ufc time zone

You're not changing TimeStamp so I don't know what you mean, but the date filter always produces UTC timestamps.

so how can i make a date field by my own time zone

My answer in I want to save index by my own time zone applies here too.

thank you .you are right but now i find a new problem that when i use date_histogram

  "aggs" : {
        "salestime" : {
            "date_histogram" : {
                "field" : "@timestamp",
                "interval" : "day"

"aggregations": {
    "salestime": {
      "buckets": [
          "key_as_string": "2018-04-02T00:00:00.000Z",
          "key": 1522627200000,

it use utc time zone . so can i use my time zone at here?

I don't know. I suggest you post a new topic in the Elasticsearch category as this isn't a Logstash question.

ok thank you
