Example 1 with MetricsRetriever

use of ddf.metrics.reporting.internal.MetricsRetriever in project ddf by codice.

the class RrdMetricsRetrieverTest method testMetricsCsvDataWithGauge.

@Test
public void testMetricsCsvDataWithGauge() throws Exception {
    String rrdFilename = TEST_DIR + "queryCount_Gauge" + RRD_FILE_EXTENSION;

    String csv = metricsRetriever.createCsvData(rrdFilename, START_TIME, endTime);
    // Break up CSV data into its individual lines
    // Each line should have 2 parts (cells)
    // The first line should be the column headers
    String[] csvLines = csv.split("\n");
    // Verify that number of lines should be the column headers + (number of samples - 1)
    // Since 3 samples were taken, but only 2 are added to the RRD file due to averaging,
    // expect 2 lines of data and the one line of column headers.
    assertThat(csvLines.length, equalTo(7));
    // column headers
    assertThat(csvLines[0], equalTo("Timestamp,Value"));
    String[] cells = csvLines[1].split(",");
