Example 1 with TcpDiscoveryMetricsUpdateMessage

use of org.apache.ignite.spi.discovery.tcp.messages.TcpDiscoveryMetricsUpdateMessage in project ignite by apache.

the class CacheMetricsCacheSizeTest method testCacheSize.

/**

    assertEquals(ENTITIES_CNT, sizeNode0 + sizeNode1 + sizeNode2);
    // Client metrics
