I'm not able to find the variable that holds the Message Type in event name, "on_association_requested" and "on_association_released" methods. If we give event.event.name it results in "EVT_REQUESTED" or "EVT_RELEASED".
INCOMING DIMSE MESSAGE
D: Message Type                  : C-ECHO RQ
D: Presentation Context ID       : 1
D: Message ID                    : 1
D: Data Set                      : None
END OF DIMSE MESSAGE
I tried to get the Message Type, I was not able to find how.
There is no DIMSE message type during association request. Only after an association has already been through request and acceptance are DIMSE messages allowed to be sent.
pynetdicom on_association_requested() get request type (C_FIND, C_ECHO etc)
