Hello,  
I have pipelines with dozen of inputs/filters  
For some jdbc input, i meet errors :

> [2018-03-19T13:19:00,524][ERROR][logstash.inputs.jdbc] Unable to connect to database. Tried 1 times {:error\_message=\>"Java::JavaSql::SQLRecoverableException: IO Error: The Network Adapter could not establish the connection"}

Every input{} in the logstash conf files have id

> input { jdbc {id =\> "my\_input\_id"

Is there a way to configure log4j to have this id shown in logstash log  
Something like

> [2018-03-19T13:19:00,524][ERROR][logstash.inputs.jdbc my\_input\_id]....

I've dug in logstash sources. If I'm not mistaken, its not possible.  
I will try to implement it.
