Example 1 with ScopeFormats

use of org.apache.flink.runtime.metrics.scope.ScopeFormats in project flink by apache.

the class MetricRegistryTest method testScopeConfig.

/**
	 * Verifies that the scope configuration is properly extracted.
	 */
@Test
public void testScopeConfig() {
    Configuration config = new Configuration();
    config.setString(ConfigConstants.METRICS_SCOPE_NAMING_TM, "A");

    config.setString(ConfigConstants.METRICS_SCOPE_NAMING_TASK, "C");
    config.setString(ConfigConstants.METRICS_SCOPE_NAMING_OPERATOR, "D");
    ScopeFormats scopeConfig = MetricRegistryConfiguration.createScopeConfig(config);
    assertEquals("A", scopeConfig.getTaskManagerFormat().format());
    assertEquals("B", scopeConfig.getTaskManagerJobFormat().format());
    assertEquals("C", scopeConfig.getTaskFormat().format());
    assertEquals("D", scopeConfig.getOperatorFormat().format());
}
