Hello,

Can you be more explicit on your request? What exactly do you need to extract with a grok filter?

Dear Marius\_Dragomir,

I am trying to extract **MY LOG Timestamp** to **Logstash Timestamp**.

######################################################################  
**Message** : "message": "2020-03-08 08:55:12,415 localq-stats-0 INFO [http-nio-8080-exec-25] loggingFilter - Recieved 'GET' request from user  
'anonymousUser' accessing from '172.115.133.50' url:'[http://www.mercurycards.com/gateway/platform-services/api/v1/maintenance/isMa-intenanceActive](http://www.mercurycards.com/gateway/platform-services/api/v1/maintenance/isMa-intenanceActive)'

######################################################################

**Need to extract timestamp from the above and replace it with logstash timesatmp**

I am passing parameters in .conf file like this

input {  
# File paths must be absolute

```
    file {
            type => "Monitor Logs"
            add_field => { "project" => "estro"}
            path => "/etc/monitor*.log"
            start_position => "beginning"
            sincedb_path => "/dev/opt"
            codec => multiline {
            pattern => "^%{TIMESTAMP_ISO8601}"
            negate => true
            what => "previous"
            }

```

}  
}

filter {  
grok {  
match =\>{  
"message" =\> "^%{TIMESTAMP\_ISO8601}"}

}

date {  
match =\> ["@timestamp" , "(?[\d-\s:]+)"]  
target =\> "@timestamp"  
timezone =\> "UTC"  
}  
}

output {

```
    elasticsearch{

```

hosts=\>["localhost:9200"]  
index=\>"estros"  
}  
#stdout{codec=\> rubydebug }  
}
