Hi,

See maximum CPU usage reported of 50000+ percent and some ugly spike on graph. This is mdb101 though I have seen it on other hosts too.

Tasks

1. Deploy new formula developed by Mykola Marzhan

   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])))
