I have 10 RDS instances on AWS and everything is running fine. But, the response from qan and grafana are very slow. I can’t even open both at a time.

What are the monitoring machine specs? (where you run docker container).  
I would recommend a machine with at least 2GB RAM.

Also you may want to look at [url][Percona Monitoring and Management](https://www.percona.com/doc/percona-monitoring-and-management/faq.html#how-to-control-memory-consumption-for-prometheus%5B/url%5D)

It’s AWS EC2 instance with 1CPU, 2GB RAM, 320GB disk.  
I checked the status on [url][http://server/prometheus/targets[/url]](http://server/prometheus/targets%5B/url%5D).  
Out of all metrics collection resolutions(hr,lr and mr), lr status is UP and rest of all are DOWN.Error is “context deadline exceeded”.
