We just released the latest version of Drupal Monitor. There are multiple improvements in the drupalmonitor.com client as well as on the drupalmonitor.com site dashboard. You can download version 1.7 here. We highly recommend to update the module right away. You simply need to copy the files to the current module folder. There are no DB updates.

We recently introduced Drupal Farm status feature which you seem to like. We could double the Drupal sites that are monitored with drupalmonitor.com.

Feedback

As always, we are happy to receive any feedback. A Drupal 7 version is still not available. We are hard working on a D7 version. Also, we gonna release the module an drupal.org soon as an official drupal.org project.
