Metrics are important.
No, not your load average.1 Your business metrics are important. Are your signups falling? Maybe it’s a:
- Marketing problem
- Technical problem
- PR problem
You only know this if you’re recording it. There’s many ways to do this, of course, and there’s also many ways to display that information, to alert on certain thresholds (“> 10 signups in last 24 hours!”) or to check-in on progress.
If you use Heroku and aren’t recording metrics, Librato just upgraded their add-on to make it really easy and completely agnostic to the technology you use.
Or, whatever you use. I’m pretty sure it can print to
That’s it. Librato pulls that in through Heroku’s logging platform and renders a dashboard for you. Alerts with threshholds can be set on individual metrics to notify you of deviations.
It’s $19 a month3 for a 2 dyno plan, covering 20 metrics with a 1 year retention period. Well worth it, in my opinion.
Okay, yea, your technical metrics can be really useful for debugging problems and alerting you early. But, conciously putting business metrics first helps you prioritize and focus on what’s important. ↩
Is there anything that doesn’t? ↩
They have a free plan that defaults to adding a bunch of Heroku-esque metrics such as dyno memory usage, but the custom metrics as noted above are only available on paid plans, which $19 is the cheapest of. ↩
