Hello,

See the next debug info in my telegraf.log

2019-03-21T12:48:32Z D! [outputs.influxdb] buffer fullness: 0 / 10000 metrics.

buffer fullness: 0 / 10000 metrics.

Does this mean that telegraf is not sending anything to influxdb because the buffer is continuously full ?  
Can you help me how to understand these debug messages ?

Thanks  
Johan

This means the buffer is now empty, with 0 metrics out of a max size of 10k, because everything was successfully written.
