Monitor IO/traffic to a replica

#1

Hi,

Is there a way to monitor the IO to a replica? For example if I have 4 nginx replicas running and I’m using a load balancer how can I check to be sure that the replicas are being loaded evenly?

Thanks,

Rob

It really depends on how you are doing monitoring :-). If you are using Prometheus, you will probably have a timeseries with a dimension for each nginx pod or something.

Others solutions may provide different ways. Another solution that I used in the past is signalfx, and you could query that in the time series too.

If you want to see something and not store it, like just to play with, you can probably enable some status module in nginx and query each instance individually? Not sure :slight_smile:
