Is there an API that my Google App Engine app can call when signed in as the as the app admin that would return information on the number of errors (404, 500, etc.) my app is returning?
I'd like to setup a simple cron job in my application to count the number of errors that my app is returning every few minutes and send me an email if the error rate becomes unexpectedly high. I'd like to avoid having to scrape the information from the Appspot dashboard or run another process outside of my app.
The closest thing to what you need is probably LogService API
Note that it isn't available for Java runtime (yet, I assume).
