|Trace field name||Nova database fields|
|START_SEC||derived from START_TIME|
|FINISH_SEC||derived from FINISH_TIME|
|EVENT_DURATION||derived from START_TIME and FINISH_TIME|
Details of each trace fields:
- INSTANCE_UUID – This is unique for each KVM instance created by OpenStack.
- EVENT – Event corresponds to the type of action performed on an OpenStack instance, such as Create, Stop, Start, Delete etc.
- START_TIME (yyyy-MM-dd HH:mm:ss.SSS) – This fields identifies the time when a related event started executing, such as when an instance creation started or a instance deletion operation started.
- START_SEC – Time difference, in seconds, between the recorded time of the first event and the start of the current event.
- FINISH_TIME (yyyy-MM-dd HH:mm:ss.SSS)- This fields identifies the time when a related event completed
- FINISH_SEC – Time difference, in seconds, between the recorded time of the first event and the finish time of the current event.
- EVENT_DURATION – This is the required time, in seconds, for each action event, i.e. the difference between START_TIME and FINISH_TIME.
- RESULT – Status of each action event. If the result is not success or null, then this action event was not successfully.
- MEMORY_MB – Amount of RAM assigned to an instance at creation.
- DISK_GB – Amount of disk assigned to an instance at creation.
- VCPUS – Number of virtual CPUs assigned to an instance at creation.
- INSTANCE_NAME – This is the name provided by the user while creating the VM. This name is not unique. Many instances can have the same instance name.
- USER_ID – The user identifier of the account from which the VM was created.
- PROJECT_ID – the project identifier of the account from which the VM was created.
- HOST_NAME(PHYSICAL) – Name of the physical computer hosting the KVM instance.
