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.

sorry…the meaning of the image is “The page is not responding, you can wait for the page to resume response, or exit” .

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 , 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 for the update, as that could help someone in the future. Did 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. :slight_smile:
