I experience intermittent timeout when calling service in kubernetes. The frequency between 0 to 2 times a day, each happens in the duration of 1 minute. First I thought it was the cpu overload on the service, but reviewing the average cpu load 1 minute, i can’t find any fluctuation, and I check the application log, each request can be replied below 2msec.
I suspect this is related to the issue in kubernetes cluster itself, but have no idea on how to check on this. Could anyone help on on to check on the performance of following in kube ?
