I would like to know more details and impact on aws cloud watch metrics- aws docs does have much details on metrics
what is the difference between below metrics ?
What is the impact on application or aws instance if below alerts triggers ?
Cloudwatch checking these errors in logs ?
These metrics are related to your load balancer. Here is my explanation:
Internal Server Error
, Not Implemented
(e.g., the server expects POST but the client sends GET), Gateway Timeout
(e.g., the server executes a slow db query and
the result does not come back in time), etc.If all these alarms are triggered at once, there is probably high load on your server and it is not functioning optimally. More than that, though, is hard to say. You need to check the maximum number of errors. The most important one is 5XX (number 1). The load balancers, publish these metrics to CloudWatch and these don't have anything to do with your application log (if I understood the question correctly).
