func (*NovaPlugin) CollectMetrics ¶
func (self *NovaPlugin) CollectMetrics(mts []plugin.MetricType) ([]plugin.MetricType, error)
CollectMetrics returns filled mts table with metric values. Limits and quotas are colllected once per tenant. All hypervisor related statistics are collected in one call. This method also performs lazy initalization of plugin. Error is returned if initalization or any of required call failed.
func (*NovaPlugin) GetConfigPolicy ¶
func (self *NovaPlugin) GetConfigPolicy() (*cpolicy.ConfigPolicy, error)
func (*NovaPlugin) GetMetricTypes ¶
func (self *NovaPlugin) GetMetricTypes(cfg plugin.ConfigType) ([]plugin.MetricType, error)
GetMetricTypes returns list of possible namespaces. Namespaces involving limits or quotas are constructed per tenant. Namespaces for hypervisors are constructed in single api call. This method also performs lazy initalization of plugin. Returns error if initalization or any request failed.
