Hi [next1009](https://percona.vanillacommunities.com/profile/x/x/38295), can you clarify dashboard? (because we have several cpu graphs) ---

can you try to use the following Query in graph? ```auto sum( rate(node_cpu{instance="$host", mode!="idle"}[$interval])) by (mode) * 100 / scalar(sum(rate(node_cpu{instance="$host"}[$interval]))) or sum(irate(node_cpu{instance="$host", mode!="idle"}[5m])) by (mode) * 100 / scalar(sum(irate(node_cpu{instance="$host"}[5m]))) ``` it is needed to click on graph name, open for edit, open “metrics” tab and replace Query. please find the screenshot [IMG2=JSON]{“data-align”:“none”,“data-size”:“full”,“width”:“800”,“src”:“https://www.percona.com/forums/filedata/fetch?id=48137&d=1492075788”}[/IMG2] ---

can you open only CPU usage graph and open “Developer Tools” in your browser? Do you see any errors in javascript “Console” tab or any issues in “Network” tab? ---

I was selected time range Last 24 Hours. “cpu usage” graph is timeout error. selected under 12 hours then it’s loaded but very slow. ![photoid=48758](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/f/f005988570eaebd725a65a016250cc205606d6ce.jpeg) ![photoid=48759](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/2/26e411088dedde4678b1f2328339b3e4c66282c9.jpeg) ---

Can you change “Resolution” value from “1/1” to “1/10” and “Min step” to “5m”? don’t forget to click “Save dashboard” button on the top. these changes radically decrease the amount of transferred data from grafana backend. ---

> [@](#): > > i wonder why “cpu usage” graph is very slow it is slower that other graphs because it filters (idle metric) and aggregates (sum and count functions) values. but anyway it should work fine and load values in few seconds. 7 days graph - [https://pmmdemo.percona.com/graph/da…=now-7d&to=now](https://pmmdemo.percona.com/graph/dashboard/db/system-overview?orgId=1&from=now-7d&to=now) you can compare loading time
