Simplify getting info and stats from a local haproxy stat file socket.
npm install haproxy-stat
var haproxystat = require('haproxy-stat');
var hastat = haproxystat({ socketPath: '/tmp/haproxy.sock' });
Get basic info from HAProxy.
hastat.showInfo(function (err, data) {
console.log(data);
});
data is an object with the following properties:
{
name: 'HAProxy',
version: '1.4.18',
release_data: '2011/09/16',
nbproc: '1',
process_num: '1',
pid: '30984',
uptime: '0d 2h01m42s',
uptime_sec: '7302',
mem_max_mb: '0',
ulimit_n: '8210',

}
Get data from HAProxy stats via show stats command. Detailed date described here.
hastat.showStat(function (err, data) {
console.log(data);
});
data is an array of objects like the following:
