I was hunting for errors in log files and opened /home/yellowtent/platformdata/collectd/collectd.log
and found a looping error with a bunch of docker related stats :grc tail -f collectd.log

anyone having the same ?

@rmdes I have no such log file there.
Only collectd.conf and collectd.conf.d/ full of app .conf files.However
in the collectd.conf file this line points to a different path
File "/home/yellowtent/platformdata/logs/collectd/collectd.log"
this is different from your path.
Looking there:
-rw-r--r-- 1 yellowtent yellowtent 6.1M Nov 9 16:30 collectd.log -rw-r--r-- 1 yellowtent yellowtent 11M Nov 7 06:25 collectd.log.1
same errors.

Ah, this happens because those apps are "stopped" and thus there are no metrics to collect.

This is fixed in the next release. Thanks for reporting!
