Thank you for your response, it was really helpful. I was trying to figure out what are the next steps in the sporadics metrics side and you've made them more clear now. I'll report to my team so we can start the work. :)

Assunto: [Monasca] Sporadic metrics
thanks for your interest in our project and sorry for replying so late.
We are happy that you're willing to contribute to the development of
The incentive for this development is to introduce the possibility to
create alarms in Monasca based on event like metrics. E.g. A metric is
generated every time when an error in the given log-file appears. Such
metric is different from the standard Monasca metric in the way that it
does not appear on the regular, periodic basis. You can read a little
more about it here , but the blueprint itself is outdated and the
The main logic for alarm creation has been moved to
"deterministic_alarm" topic  and Tomasz works currently on that. Your
reviews are very welcome.
The changes in "sporadic_metric" topic  are meant to give the user
information that a given metric is of sporadic (non-periodic) character.
It will have no influence on monasca-thresh. Tomasz has put the code
that he already had in this topic but he must focus on
"deterministic_alarm" now, so please feel free to submit your patch-sets
if you want. Apart from the existing changes also changes in monasca-ui
and python-monascaclient repos are needed to display the 'sporadic'
attribute of the metric for the user. You could compare this change in
If you have questions to the implementation of "sporadic metrics", I
think the existing changes in gerrit  are the best place for exchange
and communication at the moment. Actually I should have updated the
blueprint for that. Sorry, my fault.
So, have fun with the code :)
P.S. Please note, I will be in holidays for the next two weeks.
