Hardware monitoring

hello guys,

I have a question regarding the monitoring of the core in a RouterBoard mikrotik.
it can monitor 12 cores, but I can not create a panel in with the total usage information, always the percentage of each core.
the doubt that I have is possible general a monitoring all the core informing the actual total and current use?
I saw that it is possible to do one by elasticsearch datasources, which is native in grafana.
Or in case it is necessary to install another datasources for this function?

tks for attention.
