As Mr. Hunter mentions, it can be hard to get a general idea of system status.. (since applications exist "within" different parts of the Appengine infrastructure. There is no global system state.)
But, here is an alternative site that I use for a general sense of how the Appengine Datastore is operating (You can compare all sorts of metrics from AWS and GAE): http://amistrongeryet.com/dashboard.jsp <http://amistrongeryet.com/dashboard.jsp>There is a specific metrics page for "GAE Datastore: read (no transaction)": http://amistrongeryet.com/op_detail.jsp?op=gae_db_readNonTransactional It shows a 1 Month graph of read performance.. with Median, Mean, 90th and 99th percentile results. This lets you see fairly easily if any Datastore issues have popped up recently. (I generally just look at 99th percentile when looking for big issues.)
