nightcap

Monitor your Mongo capped collections. If you're using a circular queue, you can make sure data is not overwritten.

installation

npm install nightcap

usage

var Nightcap = require('nightcap');

var nc = new Nightcap(mongouri, {
  query: { isProcessed: false },
  targetPercentage: 50,
  collection: 'messagequeue'
});

nc.on('breach', function(percentage) {
  console.log('%s%% of your documents are waiting to be processed!', percentage);
});

The above will log to the console if number of unprocessed documents exceeds 50% of the collection size.
