Hello,

I'm not getting the desired output for this example that I"m testing on my windows machine.

**file: sqllog**  
INFO - 12345 - TASK\_START - start  
INFO - 12345 - SQL - sqlQuery1 - 12  
INFO - 12345 - SQL - sqlQuery2 - 34  
INFO - 12345 - TASK\_END - end

**file: logstash-sql.conf**  
input {  
file {  
path =\> "C:\logstash\sqllog"  
start\_position =\> beginning  
}  
}

```
filter {
   grok {
     match => ["message", "%{LOGLEVEL:loglevel} - %{NOTSPACE:taskid} - %{NOTSPACE:logger} - %{WORD:label}( - %{INT:duration:int})?"]
   }

   if [logger] == "TASK_START" {
     aggregate {
       task_id => "%{taskid}"
       code => "map['sql_duration'] = 0"
       map_action => "create"
     }
   }

   if [logger] == "SQL" {
     aggregate {
       task_id => "%{taskid}"
       code => "map['sql_duration'] += event['duration']"
       map_action => "update"
     }
   }

   if [logger] == "TASK_END" {
     aggregate {
       task_id => "%{taskid}"
       code => "event['sql_duration'] = map['sql_duration']"
       map_action => "update"
       end_of_task => true
       timeout => 120
     }
   }
 }

 output {
  stdout {}
 }

```

**Running Logstash:**  
_\>logstash.bat -f C:\logstash\logstash-sql.conf -w 1_

Settings: User set pipeline workers: 1, Default pipeline workers: 4  
Pipeline main started  
2016-08-03T09:56:50.382Z PGGV999 INFO - 12345 - TASK\_START - start  
2016-08-03T09:56:50.569Z PGGV999 INFO - 12345 - SQL - sqlQuery1 - 12  
2016-08-03T09:56:50.570Z PGGV999 INFO - 12345 - SQL - sqlQuery2 - 34

The pipeline ends here, but I'm expecting:  
{  
"message" =\> "INFO - 12345 - TASK\_END - end",  
"sql\_duration" =\> 46  
}

Can someone help what I'm doing wrong here?

Thanks.

I could solve it myself. The sqllog did not have a "\n" for the last line and it was troubling the logstash execution. Introducing a "\n" for last line helped to get the right output.

Also used rubydebug codec to understand how it is printing.
