Examples with TagValue com.google.instrumentation.stats.TagValue used on opensource projects

Example 1 with TagValue

use of com.google.instrumentation.stats.TagValue in project grpc-java by grpc.

the class AbstractInteropTest method checkTags.

private static void checkTags(MetricsRecord record, boolean server, String methodName, Status.Code status) {
    TagValue methodNameTag = record.tags.get(server ? RpcConstants.RPC_SERVER_METHOD : RpcConstants.RPC_CLIENT_METHOD);
    assertNotNull("method name tagged", methodNameTag);

    TagValue statusTag = record.tags.get(RpcConstants.RPC_STATUS);
    assertNotNull("status tagged", statusTag);
    assertEquals(status.toString(), statusTag.toString());
}

Example 2 with TagValue

use of com.google.instrumentation.stats.TagValue in project grpc-java by grpc.

the class ServerCallImplTest method checkStats.

private void checkStats(Status.Code statusCode) {
    StatsTestUtils.MetricsRecord record = statsCtxFactory.pollRecord();
    assertNotNull(record);
    TagValue statusTag = record.tags.get(RpcConstants.RPC_STATUS);

    assertNull(record.getMetric(RpcConstants.RPC_CLIENT_UNCOMPRESSED_REQUEST_BYTES));
    assertNull(record.getMetric(RpcConstants.RPC_CLIENT_UNCOMPRESSED_RESPONSE_BYTES));
    // The test doesn't invoke MessageFramer and MessageDeframer which keep the sizes.
    // Thus the sizes reported to stats would be zero.
