ELB metrics not found in CloudWatch

I have a load balancer in ap-northeast-1 (Tokyo) region.

According to this article, I think I should be able to find Backend Connection Errors, Surge Queue Length, and Spillovers metrics in CloudWatch. But I can't find them.

Are these metrics only available in specific regions?

I've googled for hours but failed to find an answer.

Currently I can see 15 metric for my ELB, which are

  1. Average Latency

  2. Sum Requests

  3. Sum HTTP 5XXs

  4. Sum HTTP 4XXs

  5. Sum ELB 5XXs

  6. Sum ELB 4XXs

  7. Target connection errors

  8. Sum rejected connections

  9. Target TLS Negotiation Errors

  10. Sum HTTP 3XXs

  11. Sum HTTP 3XXs

  12. Sum HTTP 2XXs

  13. Active Connection Count

  14. New Connection Count

  15. Processed Bytes

The AWS documentation lists:

The Classic list includes:

  • BackendConnectionErrors: The number of connections that were not successfully established between the load balancer and the registered instances.
  • SurgeQueueLength: The total number of requests that are pending routing.
  • SpilloverCount: The total number of requests that were rejected because the surge queue is full.

If these metrics are not appearing, it may be because the values are zero. Typically, zero values are not sent to Amazon CloudWatch.
