Hi, I have been wrestling with Amazon's CloudWatch API with limited success. Does anyone know of any good resources (other than amazon's api docs) for using the APIs. I have tried to run them using the PHP library for CloudWatch but get nothing but error codes. I am configuring the GetMetricStatisticsSample.php file as follows:

$request = array();
$endTime = date("Y-m-d G:i:s");
$yesterday  = mktime (date("H"), date("i"), date("s"), date("m"), date("d")-1, date("Y"));
$startTime = date("Y-m-d 00:00:00", $yesterday);
$request["Statistics.member.1"] = "Average";
$request["EndTime"] = $endTime;
$request["StartTime"] = $startTime;
$request["MeasureName"] = "CPUUtilization";
$request["Unit"] = "Percent";

invokeGetMetricStatistics($service, $request);

But this returns "Caught Exception: Internal Error Response Status Code: 400 Error Code: Error Type: Request ID: XML:"

I have also tried from command line as follows -

    set JAVA_HOME=C:\Program Files\Java\jre1.6.0_05
    set AWS_CLOUDWATCH_HOME=C:\AmazonWebServices\API_tools\CloudWatch-1.0.0.24
    set PATH=%AWS_CLOUDWATCH_HOME%\bin

    mon-list-metrics

but get C:|Program' is not recognized as an internal or external command...

any suggestions? cheers
