[openstack-dev] [charms] ceilometer metering and event time-to-live defaults

Hi All

In the current ceilometer charms, we retain all ceilometer data
indefinitely;  the TTL can be overridden by users using configuration
options, but to me it feels like maybe retaining all data forever by
default is a trip hazard to users, and the actions required to backout of a
full DB for not that nice:

Any thoughts? What TTL defaults do deployments (and other deployment tools)
typically use for ceilometer data?

Cheers

James
