Examples with RpcMetrics org.apache.hadoop.ipc.metrics.RpcMetrics used on opensource projects

Example 1 with RpcMetrics

use of org.apache.hadoop.ipc.metrics.RpcMetrics in project hadoop by apache.

the class TestProtoBufRpc method testLogSlowRPC.

@Test(timeout = 12000)
public void testLogSlowRPC() throws IOException, ServiceException {
    TestRpcService2 client = getClient2();
    // make 10 K fast calls
    for (int x = 0; x < 10000; x++) {
        try {
            client.ping2(null, newEmptyRequest());
        } catch (Exception ex) {
            throw ex;
        }
    }
    // Ensure RPC metrics are updated
    RpcMetrics rpcMetrics = server.getRpcMetrics();
    assertTrue(rpcMetrics.getProcessingSampleCount() > 999L);
    long before = rpcMetrics.getRpcSlowCalls();
    // make a really slow call. Sleep sleeps for 1000ms
    client.sleep(null, newSleepRequest(SLEEP_DURATION * 3));
    long after = rpcMetrics.getRpcSlowCalls();
    // Ensure slow call is logged.
    Assert.assertEquals(before + 1L, after);
}

Example 2 with RpcMetrics

use of org.apache.hadoop.ipc.metrics.RpcMetrics in project hadoop by apache.

the class TestProtoBufRpc method testEnsureNoLogIfDisabled.

@Test(timeout = 12000)
public void testEnsureNoLogIfDisabled() throws IOException, ServiceException {
    // disable slow RPC  logging
    server.setLogSlowRPC(false);
    TestRpcService2 client = getClient2();
    // make 10 K fast calls
    for (int x = 0; x < 10000; x++) {
        client.ping2(null, newEmptyRequest());
    }
    // Ensure RPC metrics are updated
    RpcMetrics rpcMetrics = server.getRpcMetrics();
    assertTrue(rpcMetrics.getProcessingSampleCount() > 999L);
    long before = rpcMetrics.getRpcSlowCalls();
    // make a really slow call. Sleep sleeps for 1000ms
    client.sleep(null, newSleepRequest(SLEEP_DURATION));
    long after = rpcMetrics.getRpcSlowCalls();
    // make sure we never called into Log slow RPC routine.
    assertEquals(before, after);
}
