Line B is the corresponding unhealthy host count. For Whenever, select According to AWS support: As the ELB (when configured with HTTP listeners) acts as a proxy (request headers comes in and gets validated, and then sent to the backend) the latency metric will start ticking as soon as the headers are sent to the backend until the backend sends the first byte responses. For example, if you notice that latency is increasing in parallel with the request rate, it may be due to a server load issue. you can When you request statistics, the returned data stream is identified by the metric Thanks for letting us know we're doing a good The estimated number of bytes processed by an Application Load Balancer. All other brand names, product names, or trademarks belong to their respective owners. Used with Provisioned IOPS (SSD) volumes only.
