Configuration of InfluxDB retention policy unclear or not working

[tw-bert]

Hi Florian,

We're not succeeding in configuring the target retention policy.

This is what I put in /opt/Kafka/kafka_2.12-0.10.2.1/config/server.properties :

# InfluxDB metrics
kafka.metrics.reporters=com.github.fhuss.kafka.influxdb.KafkaInfluxMetricsReporter
kafka.influxdb.metrics.reporter.enabled=true
kafka.influxdb.metrics.address=http://localhost:8086
kafka.influxdb.metrics.database=telegraf
kafka.influxdb.metrics.retention=A

Expecting that the measurements will end up in retention policy A of database telegraf.
Alas, they go to the default retention policy of database telegraf. Retention policy A is present, initially created by:

create retention policy A on telegraf duration 1w replication 1 shard duration 168h

Sidenote: We have several CQ's running that downsample to longer retention policies. It's convenient for us to use the same retention scheme, be it in a 'kafka' db or in a 'telegraf' db, that's just a name.

Any hints?

Kind regards, TW
