Example 16 with MetricsRetriever

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

the class RrdMetricsRetrieverTest method testMetricsGraphWithGauge.

@Test
public void testMetricsGraphWithGauge() throws Exception {
    String rrdFilename = TEST_DIR + "queryCount_Gauge" + RRD_FILE_EXTENSION;
    long endTime = new RrdFileBuilder().rrdFileName(rrdFilename).dsType(DsType.GAUGE).build();
    MetricsRetriever metricsRetriever = new RrdMetricsRetriever();
    byte[] metricsGraph = metricsRetriever.createGraph("Query Reponse Time", rrdFilename, START_TIME, endTime);
    assertThat(metricsGraph, not(nullValue()));
    assertThat(metricsGraph.length, is(greaterThan(0)));
    // NOTE: RrdGraph provides no way to programmatically verify the title and axis label were
    // set, i.e., no getters
    // All we can verify is that this alternate createGraph() method returns a byte array of the
    // graph image. Only
    // visual inspection can verify the graph's accurracy, title, and axis labels.
    metricsGraph = metricsRetriever.createGraph("Query Reponse Time", rrdFilename, START_TIME, endTime, "My Vertical Axis Label", "My Title");
    assertThat(metricsGraph, not(nullValue()));
    assertThat(metricsGraph.length, is(greaterThan(0)));
}
