Overview ¶
Package services contain the key components of the Chainlink node. This includes the Application, JobRunner, LogListener, and Scheduler.
Application ¶
The Application is the main component used for starting and stopping the Chainlink node.
JobRunner ¶
The JobRunner keeps track of Runs within a Job and ensures that they're executed in order. Within each Run, the tasks are also executed from the JobRunner.
JobSubscriber ¶
The JobSubscriber coordinates running job events with the EventLog in the Store, and also subscribes to the given address on the Ethereum blockchain.
Scheduler ¶
The Scheduler ensures that recurring events are executed according to their schedule, and one-time events occur only when the specified time has passed.

Types ¶
type Checker ¶
type Checker interface {
// Register a service for health checks.
Register(service services.HealthReporter) error
// Unregister a service.
Unregister(name string) error
// IsReady returns the current readiness of the system.
// A system is considered ready if all checks are passing (no errors)
IsReady() (ready bool, errors map[string]error)
// IsHealthy returns the current health of the system.
// A system is considered healthy if all checks are passing (no errors)
IsHealthy() (healthy bool, errors map[string]error)
Start() error
Close() error
}
Checker provides a service which can be probed for system health.
type Config ¶
type Config interface {
BlockProfileRate() int
CPUProfileRate() int
GatherDuration() models.Duration
GatherTraceDuration() models.Duration
GoroutineThreshold() int
MaxProfileSize() utils.FileSize
MemProfileRate() int
MemThreshold() utils.FileSize
MutexProfileFraction() int
PollInterval() models.Duration
ProfileRoot() string
}
type InBackupHealthReport ¶ added in v2.4.0
type InBackupHealthReport struct {
// contains filtered or unexported fields
}
func NewInBackupHealthReport ¶ added in v2.4.0
func NewInBackupHealthReport(port uint16, lggr logger.Logger) *InBackupHealthReport
NewInBackupHealthReport creates a new InBackupHealthReport that will serve the /health endpoint, useful for preventing shutdowns due to health-checks when running long backup tasks
func (*InBackupHealthReport) Start ¶ added in v2.4.0
func (i *InBackupHealthReport) Start()
func (*InBackupHealthReport) Stop ¶ added in v2.4.0
func (i *InBackupHealthReport) Stop()
type MultiStart ¶
type MultiStart = services.MultiStart
MultiStart is a utility for starting multiple services together. The set of started services is tracked internally, so that they can be closed if any single service fails to start.
type Nurse ¶
type Nurse struct {
utils.StartStopOnce
// contains filtered or unexported fields
}
func (*Nurse) GatherVitals ¶
type ServiceCtx ¶
type StartClose ¶
type StartClose = services.StartClose
StartClose is a subset of the ServiceCtx interface.
