Status Collector

This package allows packages and applications to setup status collectors into a global place. It allows you to setup topographically named collectors that can be filtered by globbing which can then be exposed for consumption to check the status of your application.

Example

> collectors = require('status-collector'),
collectors = require('./index');
> Q = require('q');
> inspect = require('util').inspect;

collectors.register('my.cool.collector', function() { 
  return { success: true, stuff: 'and', things: true };
});

collectors.register('my.ace.collector', function() { 
  return Q().then(function() { return { success: true, woa: 'crazy'}; }); 
});

> collectors
<StatusCollector collectors=[my.ace.collector, my.cool.collector]>

Now to use them.

# run everything
collectors.execute().then(function(results) {
  console.log(inspect(results, {depth: null}));
});

> [ { name: 'my.cool.collector',
success: true,
results: { success: true, stuff: 'and', things: true } },

{ name: 'my.ace.collector', success: true, results: { success: true, woa: 'crazy' } } ]

We can filter the things to run:

collectors.execute('*.cool.*').then(function(results) {
  console.log(inspect(results, {depth: null}));
});

> [ { name: 'my.cool.collector',
success: true,
results: { success: true, stuff: 'and', things: true } }

Express integration

Add the following to your express app

myApp.use(collectors.expressApp("/my-base-path", express()));

Then hit it:

curl -k -vv  "http://localhost:4567/my-base-path-list"
curl -k -vv  "http://localhost:4567/my-base-path"

When you have something to test, lets say "my.thing.yeah"

curl -k -vv  "http://localhost:4567/my-base-path/my"
curl -k -vv  "http://localhost:4567/my-base-path/my/thing"
curl -k -vv  "http://localhost:4567/my-base-path/my/thing/yeah"
curl -k -vv  "http://localhost:4567/my-base-path/my.*"
