Types

type Condition

type Condition struct {
	// Type is the condition type. It should describe the condition of node in problem. For example
	// KernelDeadlock, OutOfResource etc.
	Type string `json:"type"`
	// Status indicates whether the node is in the condition or not.
	Status bool `json:"status"`
	// Transition is the time when the node transits to this condition.
	Transition time.Time `json:"transition"`
	// Reason is a short reason of why node goes into this condition.
	Reason string `json:"reason"`
	// Message is a human readable message of why node goes into this condition.
	Message string `json:"message"`
}

Condition is the node condition used internally by problem detector.

type Event

type Event struct {
	// Severity is the severity level of the event.
	Severity Severity `json:"severity"`
	// Timestamp is the time when the event is generated.
	Timestamp time.Time `json:"timestamp"`
	// Reason is a short reason of why the event is generated.
	Reason string `json:"reason"`
	// Message is a human readable message of why the event is generated.
	Message string `json:"message"`
}

Event is the event used internally by node problem detector.

type Severity

type Severity string

Severity is the severity of the problem event. Now we only have 2 severity levels: Info and Warn, which are corresponding to the current kubernetes event types. We may want to add more severity levels in the future.

const (
	// Info is translated to a normal event.
	Info Severity = "info"
	// Warn is translated to a warning event.
	Warn Severity = "warn"
)

type Status

type Status struct {
	// Source is the name of the problem daemon.
	Source string `json:"source"`
	// Events are temporary node problem events. If the status is only a condition update,
	// this field could be nil. Notice that the events should be sorted from oldest to newest.
	Events []Event `json:"events"`
	// Conditions are the permanent node conditions. The problem daemon should always report the
	// newest node conditions in this field.
	Conditions []Condition `json:"conditions"`
}

Status is the status other problem daemons should report to node problem detector.
