We have observed openstack user can not launch new instances due to quota limit of vcpu and instances. However, our framework does not catch this type of events and won't be able to provide information about errors.
Example of error message:
OverLimit: Over limit (HTTP Quota exceeded: code=InstanceLimitExceeded (HTTP 413) (Request-ID: req-...-...)
What we have found is that nova-api.log file generates the log entries that we are looking for as a WSGI server.
What we are going to do next is:
watching nova-api.log
collecting event messages (general and error)
making backups of log files
pouring the collected information into cloud metrics database
displaying the error frequency on the web or on cm tools or else
displaying a frequency of general user requests
Documenting all processes
This way allows us to provide rate of user (command) errors in a certain period.
BTW, the title might be misleading to this subject though.
