We have found adding simple health check pages to applications is incredibly useful. This allows people to quickly understand the health of an individual node. We often extend them to add metrics like the number of orders placed, error rates, or similar information. Using simple embedded web servers, even non-web based services can easily expose internal information over HTTP. By using microformats, these web pages can easily be scraped by other monitoring tools to become part of holistic monitoring.
