Examples with Header org.rrd4j.core.Header used on opensource projects

Example 1 with Header

use of org.rrd4j.core.Header in project ddf by codice.

the class RrdJmxCollectorTest method collectData.

private void collectData(int numRrdStepIterations) throws Exception {
    String rrdFilename = jmxCollector.getRrdPath();
    rrdDb = new RrdDb(rrdFilename);
    Header header = rrdDb.getHeader();
    // Wait for "n" iterations of RRDB's sample rate, then see if MBean value was collected
    LOGGER.debug("Sleeping for {} seconds", header.getStep() * numRrdStepIterations);
    Thread.sleep((header.getStep() * numRrdStepIterations) * 1000);
    // LOGGER.debug(rrdDb.dump());
    long endTime = Calendar.getInstance(TimeZone.getTimeZone("UTC")).getTimeInMillis() / 1000;
    // +1 because the fetch gets data for times inclusively, e.g.,
    // endTime=12345, so startTime=12345-4=12341,
    // then fetch data for timestamps 12341, 12342, 12343, 12344, 12345 (which is 5 values)
    long startTime = endTime - numRrdStepIterations + 1;
    LOGGER.debug("startTime = {}, endTime = {}", startTime, endTime);
    FetchRequest fetchRequest = rrdDb.createFetchRequest(ConsolFun.TOTAL, startTime, endTime);
    FetchData fetchData = fetchRequest.fetchData();
    double[] values = fetchData.getValues(dataSourceName);
    assertThat(values.length, is(numRrdStepIterations));
    logFetchData(fetchData, "TOTAL");
    fetchRequest = rrdDb.createFetchRequest(ConsolFun.AVERAGE, startTime, endTime);
    fetchData = fetchRequest.fetchData();
    values = fetchData.getValues(dataSourceName);
    assertThat(values.length, is(numRrdStepIterations));
    logFetchData(fetchData, "AVERAGE");
    fetchRequest = rrdDb.createFetchRequest(ConsolFun.MIN, startTime, endTime);
    fetchData = fetchRequest.fetchData();
    values = fetchData.getValues(dataSourceName);
    assertThat(values.length, is(numRrdStepIterations));
    logFetchData(fetchData, "MIN");
    fetchRequest = rrdDb.createFetchRequest(ConsolFun.MAX, startTime, endTime);
    fetchData = fetchRequest.fetchData();
    values = fetchData.getValues(dataSourceName);
    assertThat(values.length, is(numRrdStepIterations));
    logFetchData(fetchData, "MAX");
