Pulsar

The Pulsar project aim to visually render the mood, trend activity of an Application over time. Demo at http://corsair.space (Mood of itself :))

Prerequisite:

• InfluxDB (https://influxdb.com)
• Golang v1.4+

Installation Backend

Get the repo build, it's ready :)

go get github.com/samuelramond/Pulsar
go build github.com/samuelramond/Pulsar
./Pulsar

Installation Frontend

Example nginx conf file to serve frontend :)

server {
	listen 80 default;
	listen [::]:80 default;

	root /var/www/pulsar/src/github.com/samuelramond/Pulsar/frontend;

	index index.html index.htm;

	server_name _;

	location / {
		try_files $uri $uri/ =404;
	}
}

You can now connect to your front at http://your-server to change galaxy you can use http://your-server?token=<APPLICATION_TOKEN>

Configuration File:

• Todo load the whole config :)

Usage Backend:

APPLICATION_TOKEN: Autogenerated token for your application so your activity is visible in the right place

CLIENT_ID: Unique identifier for your client (nb: you can send a hash of your id as long as it is unique per client)

GROUP_ID: *Optionnal, group your client belongs to. This is only to visually draw Nebula of users

• Emit pulse:

curl '127.0.0.1:4000/pulse?token=<APPLICATION_TOKEN>&client_id=<CLIENT_ID>&group_id=<GROUP_ID>'

• Get Statistics

curl '127.0.0.1:4000/stats/loads?token=<APPLICATION_TOKEN>'

curl '127.0.0.1:4000/stats?token=<APPLICATION_TOKEN>&groupBy=<AGGREGATE_TIME>&past=<START_TIME>'

AGGREGATE_TIME: On which range aggregation shall be displayed (ex: 20min / 1h) START_TIME: range will be taken on now() - START_TIME (ex: 1d, 12h)

Nb: Be carefull when choosing your representation you may experience trouble if querying too many data (ex: past=10d & groupBy=1s --> 10243600 point in your graph)

• Receive pulse notification (websocket)

var sock = new WebSocket("ws://127.0.0.1:4000/sock");
sock.send('{"action":"joingalaxy","data":"33999f3f30f9"}');

On first connection you must send the Galaxy you want to join using your APPLICATION_TOKEN.

Philosophy:

GalaxyCluster {
	[]Galaxy {
		[]Nebula {
			[]Pulsar
		}
	}
}

Pulsar: Single Client

Nebula: Client Organization/Group

Galaxy: Application
