Elasticstack 6.1

I am trying to parse the following field/date:  
`"EventTime":"2018-02-08 12:43:35.951854Z"`

I have used:

```auto
filter {   
  date {
    match => ["EventTime", "yyyy-MM-dd HH:mm:ss:SSSZ"]
  }
}

```

```auto
filter {   
  date {
    match => ["EventTime", "ISO8106"]
  }
}

```

And they all return a `_dateparsefailure`

I am not sure how to get the date to parse correctly

> match =\> ["EventTime", "yyyy-MM-dd HH:mm:ss:SSSZ"]

Have you tried SSSSSSS instead of SSS? Also, your date has a period between the seconds and microseconds, not a colon.

> match =\> ["EventTime", "ISO8106"]

It's ISO8601.

This eventually worked

```auto
filter {   
  date {
    match => ["EventTime", "yyyy-MM-dd HH:mm:ss.SSSSSSZ", "ISO8601"]
  }
}

```

`ISO8601` itself didn't work
