Thanks for getting in touch. Could you translate the message for us please? Just that as it’s an image, I can’t cut and paste for google translate. Also if you have any error logs to share. ---

The main symptoms are “Browser page is not responding when opening home page”. My Boss advised me to optimize the parameter of grafana.Can you give me some sugesstions? ---

With the help of [Fan](https://percona.vanillacommunities.com/profile/x/x/41523) , I solved the problem. I have configured the server for home page monitoring is only the pmm’server .Before that, the home page showed all the servers being monitored. ---

Ah thank you [mengweike](https://www.percona.com/forums/member/41737-mengweike) for the update, as that could help someone in the future. Did [Fan](https://www.percona.com/forums/member/41523-fan) help you directly or just reading their past posts? Only if they reached out directly then we’d like to say “thank you” too. 🙂
