Types ¶
type Application ¶
type Application struct {
Hostname string
GeneralConfig config.GeneralConfig
DBConfig *config.DBConfig
Mailers map[string]*mailer.Mailer
Peers *libmap.TSafeMapString // Peers include self
// contains filtered or unexported fields
}
Application is the application object that runs HTTP server.
func New ¶
func New(configDir string) (*Application, error)
New is the constructor for Application struct.
func (*Application) CheckAndRunTriggers ¶
func (app *Application) CheckAndRunTriggers(refetchChecksChan <-chan bool)
CheckAndRunTriggers pulls list of all checks, distributed evenly across N master daemons, evaluates the checks and run triggers when conditions are met.
func (*Application) FullAddr ¶
func (app *Application) FullAddr() string
func (*Application) HandlePGNotificationPeersAdd ¶
func (app *Application) HandlePGNotificationPeersAdd(notification *pq.Notification) error
HandlePGNotificationPeersAdd responds to peers_add channel.
func (*Application) HandlePGNotificationPeersRemove ¶
func (app *Application) HandlePGNotificationPeersRemove(notification *pq.Notification) error
HandlePGNotificationPeersRemove responds to peers_remove channel.
func (*Application) ListenAllPGChannels ¶
func (app *Application) ListenAllPGChannels(listener *pq.ListenerConn) (bool, error)
ListenAllPGChannels listens to all predefined channels.
func (*Application) MiddlewareStruct ¶
func (app *Application) MiddlewareStruct() (*interpose.Middleware, error)
