Types

type Component 

type Component interface {
	// Defines the component name,
	// and used for the HTTP handler registration path.
	// Must be globally unique.
	Name() string

	// Returns the current states of the component.
	States(ctx context.Context) ([]State, error)

	// Returns all the events from "since".
	Events(ctx context.Context, since time.Time) ([]Event, error)

	// Returns all the metrics from the component.
	Metrics(ctx context.Context, since time.Time) ([]Metric, error)

	// Called upon server close.
	// Implements copmonent-specific poller cleanup logic.
	Close() error
}

Component represents an individual component of the system.

Each component check is independent of each other. But the underlying implementation may share the same data sources in order to minimize the querying overhead (e.g., nvidia-smi calls).

Each component implements its own output format inside the State struct. And recommended to have a consistent name for its HTTP handler. And recommended to define const keys for the State extra information field.

func GetComponent 

func GetComponent(name string) (Component, error)

type Event 

type Event struct {
	Time      metav1.Time       `json:"time"`
	Name      string            `json:"name,omitempty"`
	Type      string            `json:"type,omitempty"`       // optional: ErrCritical, ErrWarning, Info, Resolution, ...
	Message   string            `json:"message,omitempty"`    // detailed message of the event
	ExtraInfo map[string]string `json:"extra_info,omitempty"` // any extra information the component may want to expose
}

type Info 

type Info struct {
	States  []State  `json:"states"`
	Events  []Event  `json:"events"`
	Metrics []Metric `json:"metrics"`
}

type Metric 

type Metric struct {
	components_metrics_state.Metric
	ExtraInfo map[string]string `json:"extra_info,omitempty"` // any extra information the component may want to expose
}

type OutputProvider 

type OutputProvider interface {
	Output() (any, error)
}

Defines an optional component interface that returns the underlying output data.

type PromRegisterer 

type PromRegisterer interface {
	RegisterCollectors(reg *prometheus.Registry, db *sql.DB, tableName string) error
}

Defines an optional component interface that supports Prometheus metrics.

type SettableComponent 

type SettableComponent interface {
	SetStates(ctx context.Context, states ...State) error
	SetEvents(ctx context.Context, events ...Event) error
}

type State 

type State struct {
	Name      string            `json:"name,omitempty"`
	Healthy   bool              `json:"healthy,omitempty"`
	Reason    string            `json:"reason,omitempty"`     // a detailed and processed reason on why the component is not healthy
	Error     string            `json:"error,omitempty"`      // the unprocessed error returned from the component
	ExtraInfo map[string]string `json:"extra_info,omitempty"` // any extra information the component may want to expose
}

type WatchableComponent 

type WatchableComponent interface {
	Component
}

WatchableComponent wraps the component with a watchable interface. Useful to intercept the component states method calls to track metrics.
