HAProxy monitor library

Usage:

require('hapromo');

var hapromo = new Hapromo({  
  user : 'username',  
  pass : 'password',  
  host : 'somehost.com',  
  path : '/pathtostats;csv',  
  interval : 5000  
});  

hapromo.on(server_event, function(data) {  
	// Handle event  
});  

Installation:

npm install hapromo

List of built-in events:

server_up
server_down
error
update

Creating a custom filter with a handler function:

hapromo.addFilter({ criteria : [  
    { header : 'svname', op : 'ne', value : 'FRONTEND' },  
    { header : 'svname', op : 'ne', value : 'BACKEND' },  
    { header : 'scur', op : 'gt', value : function(data) { return 0.70 * data.slim; } }  
  ], handler : function(data) {  
    	console.log('High load on server %s!', data.svname);  
    	// Handle it  
	}  
});  

Same, but register as event instead:

hapromo.addFilter({ criteria : [  
    { header : 'svname', op : 'ne', value : 'FRONTEND' },  
    { header : 'svname', op : 'ne', value : 'BACKEND' },  
    { header : 'scur', op : 'gt', value : function(data) { return 0.70 * data.slim; } }  
  ], event : 'high_load'  
});
