Examples with CacheGroupIoView org.apache.ignite.spi.systemview.view.CacheGroupIoView used on opensource projects

Example 1 with CacheGroupIoView

use of org.apache.ignite.spi.systemview.view.CacheGroupIoView in project ignite by apache.

the class SystemViewSelfTest method testCacheGroupIo.

/**
 */
@Test
public void testCacheGroupIo() throws Exception {
    cleanPersistenceDir();
    try (IgniteEx ignite = startGrid(getConfiguration().setDataStorageConfiguration(new DataStorageConfiguration().setDefaultDataRegionConfiguration(new DataRegionConfiguration().setPersistenceEnabled(true))))) {
        ignite.cluster().state(ClusterState.ACTIVE);
        IgniteCache<Object, Object> cache = ignite.createCache("cache");
        cache.put(0, 0);
        cache.get(0);
        SystemView<CacheGroupIoView> view = ignite.context().systemView().view(CACHE_GRP_IO_VIEW);
        CacheGroupIoView row = F.find(view, null, (IgnitePredicate<CacheGroupIoView>) r -> "cache".equals(r.cacheGroupName()));
        assertNotNull(row);
        assertTrue(row.logicalReads() > 0);
    }
}
