Hey, I want to make a graph that shows cpu utilisation. Just one line between 0-100% showing the cpu utilisation. I’ve seen some cpu utilisation graphs, but they have 6 or something lines in them. I’m searching for a one-line solution. Kind of like the line in taskmanager in windows:

Just one line between 0-100%.

I have prometheus and node exporter. How can i do that?  
thanks

I have a bar panel with a % CPU load using this “Instant” metric:

`100 - (avg(irate(node_cpu_seconds_total{mode="idle"}[30m])) * 100)`

I have to admit I don’t really know how accurate this is or exactly what it is measuring but I found it somewhere and it seems to work for my purposes. You may be able to use something similar for a time graph.

I tested it and it works perfectly. Comparing the graph with the output op `top`, I can say that it’s very accurate. Thanks

To see total CPU utilization in one graph, we have to add two `cpu_usage_user` & `cpu_usage_system`

cpu\_usage\_user{host=~“(hostname-._)“}+cpu\_usage\_system{host=~”(hostname-._)”}

or

cpu\_usage\_user{host=“hostname”}+cpu\_usage\_system{host=“hostname”}
