It would be really good to let developers decide which metrics is the most useful to look at when autoscaling their application, especially since that is one of the big strengths in Juju - letting the experts give you sane defaults. I've been juggling the idea about integrating the Juju metrics into the CharmScaler seeing how that would give the charmers an already existing interface to specify their application metrics. However, as it stands right now, Juju only collects those metrices every five minutes which obviously wouldn't be a sufficient rate for smooth autoscaling. > > > 2017-03-20 21:54 GMT+01:00 Simon Kollberg <simon.kollb...@elastisys.com>: > >> >> >> On 20 March 2017 at 18:13, Charles Butler <charles.but...@canonical.com> >> wrote: >> >>> Greetings, >>> >>> I realized last week I had completed a review and failed to send an >>> update to the mailing list.
