      Description

      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.
      https://pmmdemo.percona.com/graph/dashboard/db/trends-dashboard?orgId=1&var-interval=$__auto_interval&var-host=mdb101

      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])))
