exim-maqilqueue.sh no retrieving data

Im stuck trying to get Exim queue statistics using exim-maqilqueue script with no success.

Script is actually working locally:

<<<app-exim-mailqueue>>>
frozen:20
bounces:20
total:27
active:7

But when try to get info via unix-agent is not working:

Some outputs:

Poller output: observium exim .Cannot create RRD for type exim - not found in definitions!

or

1. 1. 1. 1. 1.  Module Start: applications  #####

 o Applications         exim 
 o Module time          0.0016s

But no graphs are populated.
