The 'start' ..... operation starts the sysinv-api service in the active state.

The 'status' .... operation checks the status of the sysinv-api service.

The 'monitor' .... operation indicates the in-service status of the sysinv-api service.

The 'validate-all' operation reports whether the parameters are valid.

The 'meta-data' .. operation reports the sysinv's meta-data information.
