Hi all,
I 'm using logstash 6.0 version, unable to overwrite @timestamp using date filter.
**Below sample logs are**
2017-12-11 01:04:56,195 INFO XXXYXYYXYXYXY
2017-12-11 01:04:56,239 ERR XYEUUSSI
**Configurations are**
_cat /etc/logstash/conf.d/patterns_
JBOSS\_TIME\_FORMAT %{YEAR}[/-]%{MONTHNUM}[/-]%{MONTHDAY} %{TIME}
_cat jboss.conf_
filter {
grok {
patterns\_dir =\> ["/etc/logstash/conf.d/patterns"]
match =\> [
"message", "%{JBOSS\_TIME\_FORMAT:Log\_Time} %{LOGLEVEL:Log\_level} %{GREEDYDATA:LOG\_MESSAGE}"
]
}
date {
match =\> ["Log\_Time","yyyy-MM-dd HH:mm:ss,SSS"]
}
}
@Timestamp is not overwriting by date filter, Please help to debug on this.
Thanks in advance 🙂

Show an example event produced by Logstash. Use a `stdout { codec => rubydebug }` output.
