Cache Metrics

[Alper Tekinalp]

Hi all.

I have the following code:
        IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
        igniteConfiguration.setGridName("alper");
        Ignite start = Ignition.start(igniteConfiguration);

        CacheConfiguration configuration = new CacheConfiguration();
        configuration.setAtomicityMode(CacheAtomicityMode.ATOMIC)
                .setCacheMode(CacheMode.PARTITIONED)
                .setMemoryMode(CacheMemoryMode.OFFHEAP_TIERED)
                .setRebalanceMode(CacheRebalanceMode.SYNC)

.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC)
                .setRebalanceThrottle(100)
                .setRebalanceBatchSize(2*1024*1024)
                .setBackups(1)
                .setName("cemil")
                .setEagerTtl(false);
        start.getOrCreateCache(configuration);

        IgniteCache<Object, Object> cemil = start.getOrCreateCache("cemil");

        cemil.put("1", "10");
        cemil.put("2", "10");
        cemil.put("3", "10");
        cemil.put("4", "10");

        System.out.println(cemil.metrics().getOffHeapAllocatedSize());
        System.out.println(cemil.metrics().getOffHeapBackupEntriesCount());
        System.out.println(cemil.metrics().getOffHeapGets());
        System.out.println(cemil.metrics().getOffHeapHits());
        System.out.println(cemil.metrics().getOffHeapMisses());
        System.out.println(cemil.metrics().getOffHeapPuts());
        System.out.println(cemil.metrics().getOffHeapEvictions());
        System.out.println(cemil.metrics().getOffHeapHitPercentage());

All prints 0. Is that normal? Am i doing something wrong?

Hi, Alper!

Could you try to set configuration.setStatisticsEnabled(true)  and try once
again?

Cross sending this to dev.

Igniters, why does the metrics stuff have to be so confusing? Looks like if
"statisticsEnabled" is false, then metrics return all 0s. Can we at least
have a warning in the log stating that the metrics are disabled, and
explaining how to enable them?

Hi all.

Thanks for your replies. Enabling statistics fixed it.
