We send absolute counters to statsd as incremental counters

[jszwedko]

A user reported they were seeing their kafka sink internal metrics continuously increasing even when there was no traffic going into the source. They are sending their metrics to statsd over UDP. I setup nc to listen for the statsd messages and I can see that it is continuously publishing the absolute counter like:

vector.kafka_requests_bytes_total:66|c

As statsd only allows for incremental counters, it is interpreting this to mean it should increase the counter by the absolute value each time.
