The "agent" is a collection of scripts that are built to be run once off by cron jobs that are configured on the node.
There are a few "actions" that the agent performs:
Run on boot of the node. This script ensure thats all the components in the box are setup and working. This is meant to ensure that internal config of the box will also be able to connect and creates a baseline of a working unit that can be provisioned from the server after a connection has been setup.
Runs every X minutes. And collects a variety of metrics from the system to build a metric payload that is sent up to the Hub Server. Were it is saved and processed.
This is still a work in progress and more metrics might be added or removed as the project continues.
A current example of the payload:
{
"nodeid": 1,
"timestamp": "",
"node": {
"cpus": 4,
"load": "1.0, 0.6, 0.4",
"uptime": 13,
"memory": {
"free": 468,
"total": 1024
},
"disk": {
"free": 14300,
"total": 19900,
"raid": [ "ACTIVE","ACTIVE" ]
}
},
"bgan": {
"uptime": 1,
"lat": "33.123",
"lng": "18.134",
"temp": 38.4,
"ping": 1300
},
"router": {
"uptime": 100
},
"wireless": {
"uptime": 100
},
"relays": [ 1,0,0,0 ]
}To install or start developing. The project must be cloned from the repo and
npm installmust be run to setup all the configured packages. After this the project will be ready to be run by executing:
node index.js --server http://6fcf9014.ngrok.com --action (configure|metrics)Changing the action where required according to which function should be run.
