I've noticed that my mqtt metric messages are getting truncated, ie some messages are not sent by TransmitAllMetrics(). From the logs it is generating an overflow condition:

2020-08-30 07:42:37 NZST W (481206) websocket: WebSocketHandler[0x3f866d34]: job queue overflow detected 

A short delay eg 10-25ms in the TransmitMetric() function resolves it, but there is probably a better approach?

Kind regards

Derek
