Cloud Usage and API
Can someone please provide further information on what the API call:
generateUsageRecords actually does?
I know it generates usage records, but:
1. Does the Usage Server service call the generateUsageRecords API when it
runs at the scheduled time(=usage.stats.job.exec.time) or does the service
do more than that?
2. Does the generateUsageRecords API execute the Usage Server service on
demand to generate the usage records?
3. For what period does it generate the usage records eg.
i. from the last time this API function was called
ii. from the last time the usage server ran
4. If I create a VM and the corresponding ACS events are created in the
Cloud DB, if I then run generateUsageRecords soon after will the usage
records be generated for up to that point?
5. Are there any other documented details available on this API command
other than the API document?

On query #5 : there is a section called "Working With Usage" in the
Developer's Guide and another similarly named section in the
Administrator's Guide. These contain details relevant for the audience of
each guide. Why not see whether this contains the information you need. If
not, it's always possible to file a Doc enhancement bug!

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.
