Types

type ConfigDurationRecorder 

type ConfigDurationRecorder struct {
	// contains filtered or unexported fields
}

func GetConfigDurationRecorder 

func GetConfigDurationRecorder() *ConfigDurationRecorder

func (*ConfigDurationRecorder) AddOVN 

func (cr *ConfigDurationRecorder) AddOVN(nbClient libovsdbclient.Client, kind, namespace, name string) (
	[]ovsdb.Operation, func(), time.Time, error)

AddOVN adds OVN config duration to an existing recording - previously started by calling function Start It will return ovsdb operations which a user can add to existing operations they wish to track. Upon successful transaction of the operations to the ovsdb server, the user of this function must call a call-back function to lock-in the request to measure and report. Failure to call the call-back function, will result in no OVN measurement and no metrics are reported. AddOVN will result in a no-op if Start isn't called previously for the same kind/namespace/name. If multiple AddOVN is called between Start and End for the same kind/namespace/name, then the OVN durations will be summed and added to the total. There is an assumption that processing of kind/namespace/name is sequential

func (*ConfigDurationRecorder) End 

func (cr *ConfigDurationRecorder) End(kind, namespace, name string) time.Time

func (*ConfigDurationRecorder) Run 

func (cr *ConfigDurationRecorder) Run(nbClient libovsdbclient.Client, kube kube.Interface, k float64,
	workerLoopPeriod time.Duration, stop <-chan struct{})

Run monitors the config duration for OVN-Kube master to configure k8 kinds. A measurement maybe allowed and this is related to the number of k8 nodes, N [1] and by argument k [2] where there is a probability that 1 out of N*k measurement attempts are allowed. If k=0, all measurements are allowed. mUpdatePeriod determines the period to process and publish metrics [1] 1<N<inf, [2] 0<=k<inf

func (*ConfigDurationRecorder) Start 

func (cr *ConfigDurationRecorder) Start(kind, namespace, name string) (time.Time, bool)

Start allows the caller to attempt measurement of a control plane configuration duration, as a metric, the duration between functions Start and End. Optionally, if you wish to record OVN config duration, call AddOVN which will add the duration for OVN to apply the configuration to all nodes. The caller must pass kind,namespace,name which will be used to determine if the object is allowed to record. To allow no locking, each go routine that calls this function, can determine itself if it is allowed to measure. There is a mandatory two-step process to complete a measurement. Step 1) Call Start when you wish to begin a measurement - ideally when processing for the object starts Step 2) Call End which will complete a measurement Optionally, call AddOVN when you are making a transaction to OVN in order to add on the OVN duration to an existing measurement. This must be called between Start and End. Not every call to Start will result in a measurement and the rate of measurements depends on the number of nodes and function Run arg k. Only one measurement for a kind/namespace/name is allowed until the current measurement is Ended (via End) and processed. This is guaranteed by workqueues (even with multiple workers) and informer event handlers.

type OVNDBClusterStatus 

type OVNDBClusterStatus struct {
	// contains filtered or unexported fields
}

type PodRecorder 

type PodRecorder struct {
	// contains filtered or unexported fields
}

func (pr *PodRecorder) AddLSP(podUID kapimtypes.UID, netInfo util.NetInfo)

func (*PodRecorder) AddPod 

func (pr *PodRecorder) AddPod(podUID kapimtypes.UID)

func (*PodRecorder) CleanPod 

func (pr *PodRecorder) CleanPod(podUID kapimtypes.UID)

func (*PodRecorder) Run 

func (pr *PodRecorder) Run(sbClient libovsdbclient.Client, stop <-chan struct{})

Run monitors pod setup latency
