Subject Re: Cloud Usage and API
Date Mon, 17 Jun 2013 08:06:46 GMT
1. No. APIs are for users, not for cloudstack. There is a thread running at
the scheduled time.
2. No, generateUsageRecords  API adds an usage job in database
cloud_usage.usage_job.
3. There is a thread named Heartbeat in usage server which running every
minute. It checks the database and generates the usage records from last
usage job.
4. see 3.
5. I do not know.
