cobra's Introduction

Cobra

API Server for storing and graphing real-time time-series data in MongoDB

Installation

npm install
bower install

Usage

npm start

Then open up http://localhost:8080/ in your web browser.

Screenshot

Graphing 100 sensors at rate of 1 per second. Both inserting and reading to graph in real-time, from within web-app.

Note: Pageres was used to create screenshot and could only render a few horizons with Cubism. You can install and run Cobra to test for yourself and see how 100 sensors is easily streaming.

cobra's Issues

Use Redis to check for pending insert

If the Insert takes longer than the interval between sending data (per second?) then this will cause issues and redundant inserts

Cubism graphing

Switch to using setOnInsert

See http://docs.mongodb.org/manual/reference/operator/update/setOnInsert/#up._S_setOnInsert

Instead of trying to update and then inserting on update failure and trying to update after insert; simply use setOnInsert in the initial update!
See https://github.com/Glavin001/Cobra/blob/master/server/index.js#L237-L262

Switch to using an Array instead of Object

Use Array instead of Object/Dictionary field
