statsd unable to parse metrics

[peetasan]

Using
kafka_2.11-0.11.0.2,
collectd 5.8.0.116.gcd59bf0-1~xenial with <Plugin "statsd">
I have the following errors in my collectd.log:

[2018-06-22 13:40:55] statsd plugin: Unable to parse line: "kafka.server.FetcherStats.RequestsPerSec.1MinuteRate:1.994529|g"
[2018-06-22 13:40:55] statsd plugin: Unable to parse line: "kafka.server.ReplicaFetcherManager.MaxLag:0|g|#clientId:Replica"
[2018-06-22 13:40:55] statsd plugin: Unable to parse line: "kafka.server.ReplicaFetcherManager.MinFetchRate:1.984874|g|#cli"

It seems that the messages to be sent to statsd are truncated somehow, because they look to be the same length (at least in the error message).

Hi
I am facing the exact same problem.
Did anyone ever fix this issue ?

I found the solution.
I was using telegraf with the statsd input plugin, which is what emitted those errors.
The problem is that there are 2 statsd formats: etsy and datadog. This is especially important for the way multiple tags are sent, more specifically, with which separator between tags. This exporter emits in the datadog format while the telegraf statsd plugin is working with the etsy standard.
All I needed to do what let the telegraf statsd plugin know that there is some data in the datadog format and voila, it works.
Enjoy!
