telegraf disk-input does not write to output in phusion/baseimage

Question

Just used telegraf and influxdb with some other plugins. But the output of [[inputs.disk]] is not sent to the influx-database, although the telegraf-cli prints the series:

Telegraf v1.3.5 (git: release-1.3 7192e68b2423997177692834f53cdf171aee1a88)

InfluxDB v1.3.2 (git: 1.3 742b9cb3d74ff1be4aff45d69ee7c9ba66c02565)

//edited: of course:

echo $INFLUX_DATABASE 
monitoring

If I add other inputs again, like [[inputs.diskio]], they appear in the database immediately.

Answer 1

seems like there is an issue while getting the when running telegraf as a runsv-script in phusion/baseimage
