The addition of App Engine monitoring is designed to provide customers with the ability to obtain up-to-the-second perspectives on performance and network connectivity from both inside and outside the App Engine platform. The initial release will allow for continuous monitoring of the health and performance of major App Engine infrastructure, including the DataStore, Memcache, and global network connectivity. CloudStatus uses App Engine-specific management plug-ins to collect measurements that provide administrators and developers with unprecedented insight into the health of the App Engine platform.
As part of this development, Hyperic is also announcing the availability of the first cloud-specific management plug-in for its flagship product, Hyperic HQ. The new plug-in extends the full monitoring and management capabilities of Hyperic HQ to App Engine users, enabling them to examine the performance of their own custom applications running in the cloud. This plug-in is free for download on HyperForge.
