Hello!
I created config in previous version of logstash and it was working good.
After logstash update (removed and install new version) i used settings from my config, but it doesn't parse date.
Example xml is for section in condition "else"
In example xml error fileds is TimeStamp, StartDate, EndDate, LastApp_date.
Logstash puting _dateparsefailure tag and provide this fields as string. I expect it will be date fields, EndDate will be @timestamp.
Here is my config
filter
{
        if [fields][stats_file] == "true"
        {
                grok
                {
                        match => { "message" => "\[%{DATA}\]\[%{DATA:date}\]\[%{DATA}\]\[%{DATA}\] (them\=%{DATA:them}\:)?(time\=%{NUMBER:time_stamp}\:)?(Workbench\=%{DATA:Workbench}\:)?(Appname\=%{DATA:AppName}\:)?(Brand\=%{DATA:Brand}\:)?(NLS\=%{DATA:NLS}\:)?(elps\=%{NUMBER:elps}\:)?(user\=%{NUMBER:UserNumber}\:)?(host\=%{HOSTNAME:Host}\:)?(upid\=%{NUMBER:upid}\:)?(tenant\=%{DATA:Tenant}\:)?(SessionID\=%{DATA:SessionID}\:)?(UserName\=%{DATA:UserName}\:)?(Duration\=%{NUMBER:Duration})?" }

                mutate
                {
                        convert => { "[oic][duration]" => "integer" }
                        convert => { "[oic][BuildHF]" => "integer"  }
                }
        }
}
And here is xml example, what i'm parsing:
< root >
.

.
< TimeStamp >16-10-2018 10:38:36< TimeStamp >
< StartDate >16.10.2018 10:38:36< /StartDate >
< EndDate >16.10.2018 11:40:55< /EndDate >
<LastApp_date>2018-10-16 14:40:50</LastApp_date>
.
