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
Iam facing a big issue i want to map all my three nodes CPU Usage in one graph so which query leads to that can anyone help me
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”}
