Does anyone have good explanations of the gather & write times sent to the telegraf internal stats measurements.
How do we interpret write_time_ns? If this is 1 minute for example. What does it mean? Is this a measure of latency?
internal_write
buffer_limit
buffer_size
metrics_written
metrics_filtered
gather_time_ns
write_time_ns
Nobody else using these metrics?

Here is a quick list I put together:
buffer_limit
: number of metrics in the buffer. A metric is essentially one line of line protocol.
buffer_size
: max buffer size for storing metrics. This the same as the metric_buffer_limit
in your configuration file.
metrics_written
: cumulative number of metrics written since process start.
metrics_filtered
: cumulative number of metrics filtered since process start.
gather_time_ns
cumulative time in nanoseconds that the tagged input has spent gathering its input since process start.
write_time_ns
: cumulative time in nanoseconds that the tagged output has spent writing its output since process start.
