I use logstash to store all logs from different nodes in one place. So, I use _ **logback.xml** _ on the node side and logstash udp listener on the other. In logback I use **LogstashSocketAppender** , so as I know I can't set up logs views. On the logstash side I try to parse _@timestamp_ pararm to normal view, but I failed in this. So, I use filter and mutate to add one more same as timestamp param and try to parse it like this

```
 filter {
   mutate {
    add_field => { "logstash_timestamp"=> "%{@timestamp}" }
}  
 date {
match => ["logstash_timestamp1", "YYYY-MM-dd HH:mm:ss"]
tag_on_failure => ["timestamp_parse_failed"]
target => "logstash_timestamp"
}
}

```

How can I correctly get timestamp with my pattern?

This is my logback appender

```
<appender name="stash" class="net.logstash.logback.appender.LogstashSocketAppender">
    <syslogHost>localhost</syslogHost>
    <port>12345</port>
</appender>

```

The result of my parse is: **2018-08-23T11:22:11.863**

I don't understand. Does the timestamp in `@timestamp` really have the form "YYYY-MM-dd HH:mm:ss"? Why is the date filter set up to parse `logstash_timestamp1`? Did you mean `logstash_timestamp`?
