I need a way to add a Dropdown menu ( or similar solution ) to show the metrics for only one cpu ( cpu 1 or cpu 0 ). Is this possible?
The metric is node_cpu_seconds_total
Solution
Create a custom variable named "cpu" with values 0 and 1 in Dashboard settings > Variables > New
Create the graph panel using the cpu variable (use the ":pipe" suffix to enable the use of 0 and 1 options at the same time)
