i have sent logs from filebeat to logstash with different tags to treat them with different ways so this is the format of a line of one of my log files so i don't know how to analyze it .  
17-02-2020 03:08:20TO -\> | Brand : TT | Channel : sms | user\_id : 14567 | DirNum : 96708790 | identity ( idType : 1 idNumber : G2CH136G ) | country : lybie | Msisdn : 92091418 | IMSI : 892160208015358468 Status : 1 Out Code : Error while activating the sim .  
So can anyone helps me to know how to put condition in the field status to only show the lines how met an error (who have a status different to 0) and finally to save to an index elasticsearch only timestamp , Msisdn and the error message  
i'll be very thankful if one will help me to face this issue

I would try something like

```
dissect { mapping => { "message" => "%{[@metadata][ts]}T%{}" } }
date { match => ["[@metadata][ts]", "ISO8601" ] }
grok {
    break_on_match => false
    match => {
        "message" => [
            "Status : %{NUMBER:status} ",
            "Msisdn : %{NUMBER:msisdn} ",
            "Code : %{DATA:errorMessage}"
        ]
    }
}
if [status] == "0" { drop {} }
```

thank you very much for your reply it helps me a lot to know how to deal with this problem but i don't understand how you identify fields to focus only on values in this pairs and to deal with this separator |
