As a very simple health-check, do the following:
function timeTick() {
> var startTime = (new Date().getTime());
> function onTick() {
> var interval = (new Date().getTime()) - startTime;
> if(interval > 5)
> console.log('timeTick(): WARNING: interval = ' + interval);
> }
> process.nextTick(onTick);
> }
> setInterval(timeTick, 1000);
This simply sets up a periodic timer that checks the interval between one
tick and the next. Set the threshold (5 above) to be a value that
represents the kind of latency that you consider problematic for your app.
It doesn't tell you what's causing the problem but you'll quickly get an
idea of what circumstances are triggering a problem.
