Hi,

I have a problem with `auto_flush_interval`

I want to check the command result

logstash.conf:

```auto
input {                                                                                                                                                
  exec {                                                                                                                                               
       command => "lmstat -a -c"                                                                       
       interval => "60"

             negate => true

       }                                                                                                                                               
  }                                                                                                                                                    
}                                                                                                                                                      
                                                                                                                                                       
filter {                                                                                                                                               
}                                                                                                                                                      
                                                                                                                                                       
output {                                                                                                                                               
  stdout { codec => rubydebug }                                                                                                                        
} 

```

The command result is:

```auto
Users of LicenseSoftware_01: (Total of 50 licenses issued; Total of 2 licenses in use)

Users of LicenseSoftware_02: (Total of 50 licenses issued; Total of 4 licenses in use)                                                                    
  "LicenseSoftware" v1.0, vendor: VendorName, expiry: 31-dec-2021                                                                                      
                                                                        

```

With this conf, the last line is not flush after 1 second (`auto_flush_interval` delay), but after 60 seconds (`interval` delay).

Does the `auto_flush_interval` works correctly with the `exec` module ?  
How do I flush, the `interval` value is about on day in real life ?

Does someone use `auto_flush_interval` with `exec` module ?

Thank you for your answers, it can help me a lot
