Hello everyone,

I can catch every log from the computer but I just want the log from one application. I try to make that with the processors on Winlogbeat.

1. It's is possible ?
2. Did I have to do that with a filter on Logstash ?

Here it's what I catch with the logbeat.

Actualy It's what I have from the cmd line:

```auto
Exiting: error initializing processors: failed to initialize condition: missing or invalid condition

```

And here is my Winlogbeat processors

```auto
    processors:
    - include_fields:
        when:
          winlog.event_data.ProcessName: 'C:\Program Files (x86)\Microsoft Dynamics NAV\110\RoleTailored Client\Microsoft.Dynamics.Nav.Client.exe'
        fields: [message, winlog.event_data.ProcessName, winlog.event_data.SubjectUserName]

```

Kind of regards.  
Romain

PS: I'm sorry for my english skill

Hey @Roms,

One thing you can do is to filter out all events you are not interested in, for example with something like this:

```auto
processors:
  - drop_event:
      when:
        equals.winlog.event_data.ProcessName: 'C:\Program Files (x86)\Microsoft Dynamics NAV\110\RoleTailored Client\Microsoft.Dynamics.Nav.Client.exe'

```

Hello,

I'm using this configuration on the winlogbeat agent to send specific events (4624 and 4625) generated by an application (Azure AD Connect PTA agent).  
I'm using a drop\_event processor.

This will drop every collected events that are not sent by my application.

```
winlogbeat.event_logs:
  - name: Security
    ignore_older: 24h
    event_id: 4624,4625

processors:
- drop_event.when.not.equals.winlog.event_data.ProcessName: 'C:\Program Files\Microsoft Azure AD Connect Authentication Agent\AzureADConnectAuthenticationAgentService.exe'

```

Regards,

Hey everyone,

Thank you for your answers.  
I have already tried @jsoriano solution.  
I'll see if your proposal could also work with my problem. (event\_id and the ignore\_older)  
I managed to get what I wanted in Kiabana by using KQL and isolating the logs. Which seems to be enough for what we're doing.

My only fear is that I'll end up with a log overflow.

I thank you for your answer the topic can be closed.
