I'm a fairly happy Linode customer and have been for 3 or so years. (Yes, security/transparency could be better). We've got a nodebalancer and ~10 nodes. What longview lacks for me is a mechanism for notification & alerts. The value of monitoring is only half the equation. Step two is something that either has sensible defaults or easily adjusted settings and notification when limits are exceeded or below acceptable limits. I don't want to have to constantly watch longview to see a problem.

Anyone know if it provides this, or if there are better monitoring tools or services that do?
