Hi

I am new to ELK. Need some help with some specific filters.  
I am fetching some data from a table using a logstash.conf file.

I wanted to do this:  
If status of a user is a or b or c, add a field marking them as X  
If status is d or e, add a field marking this type of data as Y

I did the following and tried adding a field called "progress", but the add\_field didn't add the progress field

filter {  
if [Status] == "In Progress"{  
mutate {  
add\_field =\> ["progress", "doing"]  
}  
}  
elseif [Status]=="Not Started" or [Status]=="Hold" {  
mutate {  
add\_field =\> ["progress", "stopped"]  
}  
}  
elseif [Status] == "Retired" or [Status] == "Production" or [Status] == "Decom" {  
mutate {  
add\_field =\> ["progress", "complete"]  
}  
}  
}

I want to create a data table in kibana based on this progress field, but it is not showing up.  
Am I doing something wrong?

Regards  
Arshdeep

mutate+add\_field expects a hash, not an array, so you should be doing

```
mutate { add_field => { "progress" => "doing" } }

```

instead of

```
mutate { add_field => ["progress", "doing"] }

```

But it will do an implicit conversion from array to hash for you, so that does not stop things working. That implies that your conditionals such as

```
if [Status] == "In Progress"{

```

are not working the way you expect. Can you show us what an event looks like in the JSON tab in Kibana?
