Apologies for the late answer @Tenzer. What do you think of moving this logic into the |
This avoid cases where the buffer is initialised but then doesn't receive any packets to send before it's flushed. That can either be because of conditional sending of metrics or because a sample rate is used which means no packets has been generated this time around. In those cases an empty UDP packet is still sent when the buffer is flushed. This fixes that by checking if there are any packets to send before attempting to send them off.
