Hi,

I’m testing graphite output for my tests with version 1.4.2. I changed the gatling.conf with these parameters:

_ **data {** _  
_**writers = [console, file,graphite]**_  
_ **reader = file** _  
_ **}** _  
_ **graphite {** _  
_ **host = "mygraphiteserver"** _  
_ **port = 2003** _  
_ **bucketWidth = 100** _  
_ **}** _

When I run the test, I have this error for each request :

_**[ERROR] [01/28/2013 14:05:29.820] [GatlingSystem-akka.actor.default-dispatcher-6] [akka://GatlingSystem/user/$B] Actor GraphiteDataWriter doesn’t support message RequestRecord(Full text,1,full text long,1359378329775,1359378329776,1359378329817,1359378329817,OK,None,List([http://myserver:4360/myApp/fulltextsearch?country=FR&language=fr&searchTerm=aTerm](http://myserver:4360/myApp/fulltextsearch?country=FR&language=fr&searchTerm=aTerm) ))**_

I don’t see where I’m wrong. Thank you for your help.

Hi,

There is nothing wrong with your configuration.  
If you got this stacktrace, it means there was a problem when GraphiteDataWriter tried to connect to your Graphite server : Graphite not started, incorrect host/port…  
You should check the first error you got when running your simulation, it should lead you to the cause of connection error.

Cheers,

Pierre

thank you a lot!

My carbon server was done (but not the webapp).

With this error message, I wrongly suspected a naming convention problem.
