Examples with MetricsFilter org.apache.hadoop.metrics2.MetricsFilter used on opensource projects

Example 1 with MetricsFilter

use of org.apache.hadoop.metrics2.MetricsFilter in project hadoop by apache.

the class MetricsConfig method getFilter.

MetricsFilter getFilter(String prefix) {
    // don't create filter instances without out options
    MetricsConfig conf = subset(prefix);
    if (conf.isEmpty())
        return null;
    MetricsFilter filter = getPlugin(prefix);
    if (filter != null)
        return filter;
    // glob filter is assumed if pattern is specified but class is not.
    filter = new GlobFilter();
    filter.init(conf);
    return filter;
}

Example 2 with MetricsFilter

use of org.apache.hadoop.metrics2.MetricsFilter in project hadoop by apache.

the class TestPatternFilter method shouldAcceptImpl.

private static void shouldAcceptImpl(final boolean expectAcceptList, SubsetConfiguration conf, List<MetricsTag> tags, boolean[] expectedAcceptedSpec) {
    final MetricsFilter globFilter = newGlobFilter(conf);
    final MetricsFilter regexFilter = newRegexFilter(conf);
    // Test acceptance of the tag list:  
    assertEquals("accepts " + tags, expectAcceptList, globFilter.accepts(tags));
    assertEquals("accepts " + tags, expectAcceptList, regexFilter.accepts(tags));
    // Test results on each of the individual tags:
    int acceptedCount = 0;
    for (int i = 0; i < tags.size(); i++) {
        MetricsTag tag = tags.get(i);
        boolean actGlob = globFilter.accepts(tag);
        boolean actRegex = regexFilter.accepts(tag);
        assertEquals("accepts " + tag, expectedAcceptedSpec[i], actGlob);
        // Both the filters should give the same result:
        assertEquals(actGlob, actRegex);
        if (actGlob) {
            acceptedCount++;
        }
    }
    if (expectAcceptList) {
        // At least one individual tag should be accepted:
        assertTrue("No tag of the following accepted: " + tags, acceptedCount > 0);
    } else {
        // At least one individual tag should be rejected: 
        assertTrue("No tag of the following rejected: " + tags, acceptedCount < tags.size());
    }
