Hi,  
could you provide additional information about your system, PMM Version, number of clients, DB engines, when it started, etc?

@Aditya1,  
You should have a dedicated 4-cpu server with 16-32GB of RAM and SSDs (or cloud equivalent) for storage of the metrics data. This type of server should be able to handle about 100-200 monitored servers.
