doesn do anything unless the server crashes. How do I monitor resources with Heartbeat?
For Heartbeat version 2, please see the Frequently Asked Questions for Heartbeat Version 2 page. In version 1.x, Heartbeat was not designed for monitoring various resources. The best answer is to upgrade to an R2-style CRM configuration. If you need to monitor some resources with the 1.x software (for example, availability of WWW server) you need some third party software. Mon is a reasonable solution.
