Explanation telegraf log

Hello,

See the next debug info in my telegraf.log

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.
