================ sprockets-status ================ Simple application status handler for Tornado. +-------------+--------------------------------------------------------+ | |GitHub| | https://github.com/sprockets/sprockets-status | +-------------+--------------------------------------------------------+ | |PyPI| | https://pypi.org/project/sprockets-status/ | +-------------+--------------------------------------------------------+ | |Docs| | https://pythonhosted.org/sprockets-status/ | +-------------+--------------------------------------------------------+ | |Coveralls| | https://coveralls.io/github/sprockets/sprockets-status | +-------------+--------------------------------------------------------+ | |Travis| | https://travis-ci.org/sprockets/sprockets-status | +-------------+--------------------------------------------------------+ This library includes a very simple ``tornado.web.RequestHandler`` that returns an applications status information. You should install the handler under the ``/status`` path for a very simple healthcheck that verifies the operation of the IOLoop (at the very least). This library is the successor to the `sprockets.handlers.status`_ library. We have moved away from a deeply nested package structure based on namespace packages because they are actually more trouble than they are worth. Simplest Example ================ The simplest example is a JSON payload that contains directly configured information. The application name and version is passed through the ``URLSpec`` keyword arguments to the status handler. .. code-block:: python from tornado import ioloop, web import sprockets_status.handlers def make_app(**settings): return web.Application([ web.url('/status', sprockets_status.handlers.StatusHandler, {'name': 'my-app-name', 'version': '1.1.1'}), # add your handlers here ], **settings) if __name__ == '__main__': app = make_app() iol = ioloop.IOLoop.current() try: app.listen(8888) iol.start() except KeyboardInterrupt: iol.stop() Running this application and retrieving the ``/status`` resource returns the following: .. code-block:: http HTTP/1.1 200 OK Content-Length: 62 Etag: "e7bca140bba5af0fdb7b9e4fab6487186d7739d2" Content-Type: application/json Server: TornadoServer/4.4.2 Date: Mon, 20 Feb 2017 12:54:47 GMT {"status": "ok", "version": "1.1.1", "name": "my-app-name"} Python Packaged Application =========================== If your application is a python package, then you can let the status handler do the work of looking up your application's name and version number from the python package metadata. .. code-block:: python from tornado import ioloop, web import sprockets_status.handlers def make_app(**settings): return web.Application([ web.url('/status', sprockets_status.handlers.StatusHandler, {'package': 'my-app'}), # add your handlers here ], **settings) if __name__ == '__main__': app = make_app() iol = ioloop.IOLoop.current() try: app.listen(8888) iol.start() except KeyboardInterrupt: iol.stop() The status handler will use ``pkg_resources`` to look up the named distribution and retrieve the package name and version for you. If you give it a package that doesn't exist, then it will return a server error so don't do that.
