> When we collect real-time metrics of resource usage in NM, we found those
> values sometimes are invalid.
> For example, the following are values when collected at some point:
> "milliVcoresUsed":-5808,
> "currentPmemUsage":-1,
> "currentVmemUsage":-1,
> "cpuUsagePercentPerCore":-968.1026
> "cpuUsageTotalCoresPercentage":-24.202564,
> "pmemLimit":2147483648,
> "vmemLimit":4509715456
> There are many negative values, there may a bug in NM.
> We should fix it, because the real-time metrics of NM is pretty important for
> us sometimes.
