Hello Didier, thanks for the reply. The capabilites API gives info about general GAE infrastructure problems. What I want to monitor ist the health of the application itself. The dashboard gives most of the vital data needed and I just want to have a scheduled job that keeps checking them to

Hi, Why would you do such a thing: if you don't want the indexes anymore, you deleted them. When you need them again in the future, you just rebuild them: the entities present in your datastore will redefine the new index entries. Indexes are anyway not accessible as such but if they were, it

Hi AppEngine Gurus, If i have a client that is capable of using HTTP pipeliing, will App Engine be able to support it? Would my app need to change in any way? If so, that gives me an easy way of making persistent connection to a single instance and also increase performance quite a bit.
