Hyperic Java APIs

Question

I have written some Java code through which I fetch metrics from Hyperic Server for some operations. I have not been able to fetch the value of these metrics.

for eq I have metric CPU Idle but when i use List<Data Point> dp= m1.getDataPoint() where m1 is the metric data object of metric CPU Idle. In the output the size of list dp is 0.

I'm having this problem with all metrics except "availability". What should I do?

I have also checked the time interval in the graphical interface; it is showing the corresponding values.

the code is

 //  m_rrc is resource ( Process Server) on agent
for (int z = 0; z < m_rrrc.size(); z++) {
    System.out.println(m_rrrc.get(z).getName())
    MetricsResponse m_mr= m_a.getMetrics(m_rrrc.get(z));

    // m_m is metric like CPU idle CPU utilization, System CPU
    List<Metric> m_m = m_mr.getMetric();

    for (int a = 0; a < m_m.size(); a++) {
        MetricDataResponse m_mdr = m_mdapi.getData(m_m.get(a), 1309147200,1309147800);
        MetricData m_md = m_mdr.getMetricData();

        System.out.println(m_md.getMetricName());

        List<DataPoint> m_dp = m_md.getDataPoint();
        System.out.println(m_dp.size());

        for (int b = 0; b < m_dp.size(); b++) {
            System.out.println("abc");
            System.out.println(m_dp.get(b).getValue());
            System.out.println("i am Prannoy Mittal");
        }
    }
}

here size of data point list in output for all metrics is zero

Here is sample source code from Hyperic (http://svn.hyperic.org/projects/hqapi/trunk/src/org/hyperic/hq/hqapi1/test/MetricData_test.java), if you can put right 'assertEquals' in your code I am sure you will see where the problem is. Good luck

    public void testGetEnabledMetricData() throws Exception {

    MetricApi api = getApi().getMetricApi();
    Resource r = getLocalPlatformResource(false, false);
    MetricsResponse resp = api.getEnabledMetrics(r);
    hqAssertSuccess(resp);

    assertTrue("No enabled metrics found for " + r.getName(),
               resp.getMetric().size() > 0);
    Metric m = resp.getMetric().get(0);

    long end = System.currentTimeMillis();
    long start = end - (8 * 60 * 60 * 1000);

    MetricDataResponse dataResponse = api.getMetricData(m.getId(),
                                                           start, end);
    hqAssertSuccess(dataResponse);
    assertTrue("No metric data found for " + m.getName(),
               dataResponse.getMetricData().getDataPoint().size() > 0);
    for (DataPoint d : dataResponse.getMetricData().getDataPoint()) {

        assertTrue("Metric point timestamp greater than end time. ts=" +
                   d.getTimestamp() + " end=" + end,
                   d.getTimestamp() <= end);
        assertTrue("Metric point timestamp less than start time ts=" +
                   d.getTimestamp() + " start=" + start,
                   d.getTimestamp() >= start);
        assertTrue("Metric value less than zero",
                   d.getValue() >= 0);
    }
}
