Hi ,

  We are injecting events to our custom plugin in ceilometer.
  The ceilometer pipeline.yaml  is configured to publish these events over 
kafka and udp, consuming these samples using kafka and udp clients.

  KAFKA publisher:
  -----------------------
  When the events are sent continously ,we can see duplicate msg's are 
recevied in kafka client.
  From the log it seems ceilometer kafka publisher is failed to send 
msg's,but still these msgs 
  are received by kafka server.So when kafka resends these failed msgs we 
can see duplicate msg's
  received in kafka client.
  Please find the attached log for reference.
  Is this know issue ?
  Is their any workaround for this issue ?

  UDP publisher:
    No duplicate msg's issue seen here and it is working as expected.

 

With Best Regards
