single message received multiple times by graylog

[BeeStingBob]

I'm getting behaviour where I send one message but graylog receives multiple, and the number received by graylog can incrementally increase with each message sent. Example, each blue bar should be one message.

initialised with

class BehaveLogger():

    def __init__(self):
        self.logger = logging.getLogger(FACILITY)
        self.logger.setLevel(logging.INFO)
        handler = graypy.GELFUDPHandler(self.host, self.port, debugging_fields=True)
        self.logger.addHandler(handler)
        self.adapter = logging.LoggerAdapter(logging.getLogger(FACILITY),
                                             {'Project_ID': PROJECT_ID,
                                              'Job_Name': JOB_NAME,
                                              })  
    def log_generic(self, doc):
                self.adapter.info(json.dumps(doc))

called with

from grayloglogger.grayloglogger import BehaveLogger

self.logger = BehaveLogger() 

for job_trace in job_traces():
    self.logger.log_generic(job_trace)

any thoughts would be appreciated?

looks like I might have been adding extra handlers .... https://stackoverflow.com/questions/37134573/python-logging-duplicates-the-log-messages
