YOULESS monitoring

HI all
We using Youless ethernet bridges to monitor energy consumption.
Is there a way to extract only the Watts from my youless webpage ?

The youless is a energy kWh meter to ethernet bridge.
(http://www.youless.nl/)

With this example URL you get the output from your kWh meter.
http://<youlessip>/a

Code: Select all

88706,639 kWh
536 Watt
0%  
*

how do we extract only the "Watt" line ???

What we want to monitor the second line.
In this example

Code: Select all

536 Watt

If my customer is using more the XXX Watt's Advanced Hostmonitor must be alerting or email the customer that he is using too much energy.

is this possible ?

many thanks in advance
Menno

offtopic : Maybe its a good idea to support those simple youless devices just as the temperature devices you support.
Lets be honest instead of 77 you will be supporting 78 test methods

if you want i can help you with testing !!! no problem at all !!!

As I understand this device does not support any other protocol (SOAP, SNMP)?
Just text over HTTP?

I don't think we will add new test for this.
Probably we can add new option for URL and/or HTTP test...

Alex

Almost any custom test can be done by Shell Sctipt test method.
What is actual source code of http page at http://<youlessip>/a ?
Does it require any authentication?
Or may be you have online access/demo for the device?

thanks for your answers

NO we do not have any authentication.
the source code of the page is
(google chrome view-source:http://192.168.1.225/a )

Code: Select all

88708,649 kWh
630 Watt

how to extract that 2nd line

Your Shell Script JavaScript script may look like the following:

Code: Select all

statusUnknown     = "ScriptRes:Unknown:"
statusOk          = "ScriptRes:Ok:"
statusBad         = "ScriptRes:Bad:"

objArgs = WScript.Arguments;

if (objArgs.length != 2) {
  WScript.StdOut.Write(statusUnknown + "Required arguments: <URL> <Threshold in wats>");
  WScript.Quit;
}

var url = objArgs(0);
var threshold = parseInt(objArgs(1),10);

var objHttp = new ActiveXObject("MSXML2.ServerXMLHTTP");
objHttp.open("GET", url, false);
try { objHttp.send(); } catch(e) {
  WScript.StdOut.Write(statusUnknown + e.message);
  WScript.Quit;
}
var data = objHttp.responseText;
data = data.split("\n");
data = data[1].split(" ");
var res = parseInt(data[0]);
if (isNaN(res)) {
  WScript.StdOut.Write(statusUnknown+"value cannot be parsed");
  WScript.Quit;
}

if (res > threshold)
{
  WScript.StdOut.Write(statusBad+res);
} else {
  WScript.StdOut.Write(statusOk+res);
}

Start cmd: cmd /c cscript /B /E:JScript %Script% %Params%
Script requires 2 parameters: <URL> <Threshold value>
E.g.
http://192.168.1.225/a 900
