Vyacheslav Daradur updated IGNITE-6630:
---------------------------------------
Affects Version/s: 2.2
> Incorrect time units of average transaction commit/rollback duration cache
> metrics.
> -----------------------------------------------------------------------------------
>
> Key: IGNITE-6630
> URL: https://issues.apache.org/jira/browse/IGNITE-6630
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.2
> Reporter: Pavel Pereslegin
> Assignee: Pavel Pereslegin
> Priority: Minor
> Labels: metrics, newbie
> Fix For: 2.4
>
>
> AverageTxCommitTime and AverageTxRollbackTime metrics in CacheMetrics counts
> in milliseconds instead of microseconds as pointed in javadoc.
> Simple junit reproducer:
> {code:java}
> public class CacheMetricsTxAvgTimeTest extends GridCommonAbstractTest {
> /** */
> private <K, V> CacheConfiguration<K, V> cacheConfiguration(String name) {
> CacheConfiguration<K, V> cacheConfiguration = new
> CacheConfiguration<>(name);
> cacheConfiguration.setCacheMode(CacheMode.PARTITIONED);
> cacheConfiguration.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
> cacheConfiguration.setStatisticsEnabled(true);
> return cacheConfiguration;
> }
> /** */
> public void testTxCommitDuration() throws Exception {
> try ( Ignite node = startGrid(0)) {
> IgniteCache<Object, Object> cache =
> node.createCache(cacheConfiguration(DEFAULT_CACHE_NAME));
> try (Transaction tx = node.transactions().txStart()) {
> cache.put(1, 1);
> // Await 1 second.
> U.sleep(1_000);
> tx.commit();
> }
> // Documentation says that this metric is in microseconds.
> float commitTime = cache.metrics().getAverageTxCommitTime();
> // But this assertion will fail because it in milliseconds and
> returns only ~1000.
> assert commitTime >= 1_000_000;
> }
> }
> }
> {code}
