Hi,  
There are 15 RDS aurora clusters to monitor, I’m using EC2 instance with t2.large instance class. I’m still seeing very slow response from grafana window and some times QAN is completely not responding. I see some metrics after restarting the admin client. Please let me know, Is there some thing I can do to get better response.

do you use 1.0.7 of PMM Server?  
grafana improved some performance in 4.0.0 version.

I recommend use instance (better CPU, EBS and Network performance).  
instances comparison [url][Amazon EC2 Instance Comparison](http://www.ec2instances.info/?min_memory=8&selected=t2.large,r4.large,r4.2xlarge,m4.4xlarge%5B/url%5D)

Also It is needed to significantly increase METRICS\_MEMORY, see the link  
[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)

and you can disable userstats and tablestats metrics for mysql  
run the following commands on all instances

```auto

pmm-admin remove mysql:metrics
pmm-admin add mysql:metrics --disable-tablestats --disable-userstats

```
