Running a Data Collector Set

To run a data collector set, you can perform one of the following actions:

• Call the IDataCollectorSet::Start method.
• Schedule the data collector set to run.
• Specify that an alert trigger a data collector set to run.

Before you can run a new data collector set, you must first call the IDataCollectorSet::Commit method.

The following example shows how to schedule a data collector set to run. You can specify one or more schedules on which to run the data collector set. This example builds on the example in Creating a Data Collector Set.

HRESULT ScheduleDCS(IDataCollectorSet* pdcs)
{
    HRESULT hr = S_OK;
    IScheduleCollection* pSchedules = NULL;
    ISchedule* pSchedule = NULL;
    SYSTEMTIME st;
    double date;
    VARIANT var;

    VariantInit(&var);
    V_VT(&var) = VT_DATE;

    // Get the collection of schedules from the data collector set. 
    hr = pdcs->get_Schedules(&pSchedules);
    if (FAILED(hr))
    {
        wprintf(L"get_Schedules failed, 0x%x\n", hr);
        goto cleanup;
    }

    // Get an instance of the Schedule object.
    hr = pSchedules->CreateSchedule(&pSchedule);
    if (FAILED(hr))
    {
        wprintf(L"CreateSchedule failed, 0x%x\n", hr);
        goto cleanup;
    }

    // Specify one or more days on which the set runs.
    // This example runs only one time.
    hr = pSchedule->put_Days(plaRunOnce);
    if (FAILED(hr))
    {
        wprintf(L"put_Days failed, 0x%x\n", hr);
        goto cleanup;
    }

    // Specify the date on which the schedule begins.
    ZeroMemory(&st, sizeof(SYSTEMTIME));
    st.wDay = 27;
    st.wMonth = 5;
    st.wYear = 2009;
    SystemTimeToVariantTime(&st, &date);
    V_DATE(&var) = date;

    hr = pSchedule->put_StartDate(var);
    if (FAILED(hr))
    {
        wprintf(L"put_StartDate failed, 0x%x\n", hr);
        goto cleanup;
    }

    // You do not have to specify an end date because the 
    // job is schedule to run only once.

    // Specify the time of day that the set runs.
    ZeroMemory(&st, sizeof(SYSTEMTIME));
    st.wHour = 10;
    st.wMinute = 30;
    SystemTimeToVariantTime(&st, &date);
    V_DATE(&var) = date;

    hr = pSchedule->put_StartTime(var);
    if (FAILED(hr))
    {
        wprintf(L"put_StartTime failed, 0x%x\n", hr);
        goto cleanup;
    }

    VariantClear(&var);

    // Add the schedule to the schedule collection.
    hr = pSchedules->Add(pSchedule);
    if (FAILED(hr))
    {
        wprintf(L"pSchedules->Add failed, 0x%x\n", hr);
        goto cleanup;
    }

cleanup:

    if (pSchedule)
        pSchedule->Release();

    if (pSchedules)
        pSchedules->Release();

    return hr;
}
