Mathijs's dashboard

We host quite some small informational sites for customers that don't get a lot of visits. Since passenger times-out processes(sites) after 10 minites, we can host many of those sites on a small server, since at any time, at most one third of the sites is 'active' (as in - visited in the last 10 minutes). Will using new relic on those apps interfere with this behavior?

What will happen if some site isn't visited for a week? Will it wake up every x minutes to report there were no hits? Or will I just not get any information for that app in my weekly email?

Thanks,
Mathijs
