The limit of 1000 metricsets has been reached, no new metricss will be created

My main question is we have 800k requests coming to our Net Core API. but if we see the count of transactions on Elastic Kabana. it shows less than the actual no of requests happening on azure. we have 4 instances of web applications on azure.

I saw this warning of the limit of 1000 metric sets. is there a way to configure it? or do you know any other way to fix the issue. Thanks
