示例1: getCacheRefresh
import org.apache.hadoop.metrics2.lib.MutableStat; //导入依赖的package包/类
MutableStat getCacheRefresh() {
return cacheRefresh;
}
示例2: testPluginRead
import org.apache.hadoop.metrics2.lib.MutableStat; //导入依赖的package包/类
@Test
public void testPluginRead() throws Exception {
// Verify precondition
assertEquals(EntityGroupPlugInForTest.class.getName(),

MutableCounterLong detailLogEntityRead =
store.metrics.getGetEntityToDetailOps();
MutableStat cacheRefresh = store.metrics.getCacheRefresh();
long numEntityReadBefore = detailLogEntityRead.value();
long cacheRefreshBefore = cacheRefresh.lastStat().numSamples();
// Generate TDM
TimelineDataManager tdm
= PluginStoreTestUtils.getTdmWithStore(config, store);
// Verify single entity read
TimelineEntity entity3 = tdm.getEntity("type_3", mainTestAppId.toString(),
EnumSet.allOf(TimelineReader.Field.class),

assertEquals(entityNew.getStartTime(), entity3.getStartTime());
// Verify multiple entities read
NameValuePair primaryFilter = new NameValuePair(
