Connect-Status is a middleware layer for Connect that provides status information, like average requests-per-second, and detailed request duration information.
This is not used in production. I'll let you know when it is.
Track a few key status metrics:
- Server uptime
- Request rate
- Request duration statistics
- Request path statistics
- Response code statistics
The simplest connect app looks just like http.Server instances from node. In fact Connect.Server inherits from http.Server.
function mock(app){
app.get('/:path', function(req, res){
res.writeHead(200, {});
res.end('Booo!');
});
}
var server = connect.createServer();
server.use("/", status.status({durations: true, paths: true, status_codes: true}));
server.use(connect.router(mock));
$ curl 127.0.0.1:8124/page_1 && echo
Hurray!
$ curl 127.0.0.1:8124/page_2 && echo
Hurray!
$ curl 127.0.0.1:8124/page_2 && echo
Hurray!
$ curl 127.0.0.1:8124/status && echo

Check out the example
You should put this middleware as early as possible to record correct durations.
First update the git submodules, which includes the Expresso TDD framework:
$ git submodule update --init
Then run the test suites located in ./test with the following command:
$ make test
Run a single test, or use a custom glob pattern:
$ make test TESTS=test/status.test.js
