I have a file named "Job Code.txt"

> job\_id=0001,description=Ship data from server to elknode1,result=OK  
> job\_id=0002,description=Ship data from server to elknode2,result=Error: Msg...  
> job\_id=0003,description=Ship data from server to elknode3,result=OK  
> job\_id=0004,description=Ship data from server to elknode4,result=OK

Here is the filter part of my .conf file but it doesn't work. How can I created new field, i.e. jobID, description, result as to be seen in kibana

> filter{  
> grok{ match =\> {"message" =\> ["JobID: %{NOTSPACE:job\_id}","description: %{NOTSPACE:description}","result: %{NOTSPACE:message}"]}  
> add\_field =\> {  
> "JobID" =\> "%{job\_id}"  
> "Description" =\> "%{description}"  
> "Message" =\> "%{message}"  
> }  
> }  
> if [job\_id] == "0001" {  
> aggregate {  
> task\_id =\> "%{job\_id}"  
> code =\> "map['time\_elasped']=0"  
> map\_action =\> "create"  
> }  
> }  
> if [job\_id] == "0003" {  
> aggregate {  
> task\_id =\> "%{job\_id}"  
> code =\> "map['time\_elasped']=0"  
> map\_action =\> "update"  
> }  
> }  
> if [job\_id] == "0002" {  
> aggregate {  
> task\_id =\> "%{job\_id}"  
> code =\> "map['time\_elasped']=0"  
> map\_action =\> "update"  
> }  
> }

I invite you to fix your grok configuration :

```
grok{
  match => {"message" => ["job_id=%{NOTSPACE:job_id},description=%{DATA:description},result= 
%{GREEDYDATA:result}"]
}

```

If in Kibana, you aim to have a field named JobID, you can directly name your field JobID in grok expression :

```
grok{
  match => {"message" => ["job_id=%{NOTSPACE:JobID},description=%{DATA:description},result= 
%{GREEDYDATA:result}"]
}
```

Given your log line format, I advice you to use "kv" filter rather than "grok" :

```
kv {
  field_split => ","
}
```
