there isn't a way to this without manually modifying the files (which can get a bit sketchy). Gnocchi is designed to capture (at most) the amount of data you define in your policy and does not prune data based on 'now' so it won't shrink on it's own over time. i guess we could support a tool that could prune based on 'now' but that doesn't exist currently. the safest way to clean old data is to delete the metric. if you want to delete only some of the metric that will be difficult. it'll require you figuring out what time range of data is stored in a given file (which is not difficult if you look at code), then properly deserialising, pruning, and reserialising (probably difficult or at least annoying). cheers, -- gord _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
