To create this graph, please follow the following steps or import {TODO}.

# First, create a new *Data Input Method*:
!petals-container-localtransporter-dim.jpg|align=center!
In the *Input String*, you will put the command line needed to get the number of delivered messages for a given message exchange status. That's why the command line ends with *<status>*.
# Add an input field to your data input method
!petals-container-localtransporter-dim-status.jpg|align=center!
# Add the output field to your data input method
!petals-container-localtransporter-dim-output.jpg|align=center!
# Create a new *Data Template*:
!petals-container-localtransporter-dt.jpg|align=center!
Select your data input method previously created as *Data Input Method*.
