how does OpenStack calculate the vcpu hours, total disk usage hours I created a cirros VM with the flavor of m1.tiny without further operation on that VM.I created it around 2 hours ago but on the dashboard"Overview", it shows that "This Period's VCPU-Hours: 44.95 This Period's GB-Hours: 44.95 This Period's RAM-Hours: 23014.62" Does anyone know how OpenStack come up with these numbers?I mean VCPU-Hours, GB-Hours, and RAM-hours?I just created a very small cirros VM without any further operations.How can this number look so big? Thank you very much. -------------- next part -------------- An HTML attachment was scrubbed...
