A simple SNMP metrics realtime visualizer
Websinema is a tool aimed at fulfilling specific purposes. It involves usage of simple network management protocol (SNMP) to gather project-specific metrics. In general production grade systems usually act as a SNMP agents serving requests on handful of metrics through UDP. Unlike widespread classic systems like Cacti or something the key purpose behind Websinema is to visualize acquired metrics in a live, realtime, short-scoped manner.
Websinema consists of Erlang backend backed with Cowboy webserver and ExtJS frontend application which involves intensive usage of the Websockets to provide long-lived connections and feed data in the realtime.
Websinema support at the moment scalar SNMP objects only: counters, integers, strings, timestamps and ticks.
In order to build a project you should execute something like that:
git clone git://github.com/keynslug/websinema.git
cd websinema
make compile
The resources required by ExtJS applications are not included in the repository so the next step will be downloading of the actual ExtJS release and placing its resources directory under .\priv\client\websinema\extjs.
Then you will need to create a standard Erlang application configuration file. By default .\default.config is meant to be the general configuration file. Consult example.config to see what things you may configure.
After you have finished with configuration and added some agents you prefer to monitor execute:
./start-app.sh
That's all, the Websinema should work. Navigate to the URL you've specified in configuration file with one of the modern browsers to see if it is true.
