It is logged from RecurringTimer#loop():
private def loop() {
try {
while (!stopped) {
clock.waitTillTime(nextTime)
callback(nextTime)
prevTime = nextTime
nextTime += period
logDebug("Callback for " + name + " called at time " + prevTime)
}
For the callback, JobGenerator has this:
private val timer = new RecurringTimer(clock,
ssc.graph.batchDuration.milliseconds,
longTime => eventActor ! GenerateJobs(new Time(longTime)),
"JobGenerator")
...
/** Generate jobs and perform checkpoint for the given `time`. */
private def generateJobs(time: Time) {
