i’ve installed pmm server v1.10.0 via docker deployment method.  
this is a dedicated server only running pmm server ,it has 16 cores/48GB RAM/1000GB SSD, monitors about 60 mysql servers.  
what puzzled me is extremely high CPU usage, almost always 100%,  
and caused bad response time.  
i used -e METRICS\_MEMORY=30720000 and -e METRICS\_RETENTION=360h to limit 30GB RAM usage, 15 days retention.

what should i do to improve pmm response?  
thanks in advance

Hi,

By default 1 sec resolution is used which is kind of expensive. You can set it to lower resolution ie 5 sec to reduce CPU usage see

hi peter,  
first of all, thank you for answering my question,  
as the document mentioned, it could be up to 5 seconds,  
is it still 5 seconds for the latest release?  
could i set it to large value? for example, 60 seconds
