[Hawkular-dev] Understanding data retention

[Gareth Healy]

A metric supports data retention (TTL); the swagger docs say this is number
of days.

   -
   https://github.com/hawkular/hawkular-metrics/blob/5eb13c6dbddafdcc0fcd5eb7fc3dacd9858e18c8/core/metrics-model/src/main/java/org/hawkular/metrics/model/Metric.java#L167


   - http://www.hawkular.org/docs/rest/rest-metrics.html#Metric

There is also a default TTL which is in days but converted internally into
seconds:

   -
   https://github.com/hawkular/hawkular-metrics/blob/39389e4bf5a988ef01cbad83b488cadd47c93066/core/metrics-core-service/src/main/java/org/hawkular/metrics/core/service/MetricsServiceImpl.java#L180

Looking at when metrics are created, i can't see any conversion from days
to seconds for metrics; so any data i create with a Metric DataRetention of
30 "days" gets removed straight away.

So my question is:

   - Are the swagger docs wrong?

or

   - Should the model convert to seconds?

Or...have i missed something... ?

Cheers.
