Cette section permet d’observer les ressources mémoire et processeur ainsi que les débits relatifs aux disques et au réseau sur la période analysée pour un élément particulier. Ce dernier étant une machine virtuelle ou un serveur physique. Les courbes en pointillé représentent les maximums observés permettant d’afficher l’heure exacte. Cette dernière est donnée au format UTC (Universal Time Coordinated). Les courbes pleines représentent la moyenne des consommations sur l’heure révolue.

RAM resource

Metric Group RAM VMware Counter Notes Stats type Unit
RAM: usage X (capacity VM/ host capacity)
RAMINTRA: usage usage Memory usage as percentage of total configured or available memory, expressed as a hundredth of a percent (1 = 0.01%). The value is between 0 and 10,000.
Virtual machine: Percentage of configured virtual machine “physical” memory: active ÷ virtual machine configured size.
Host: Percentage of available machine memory:consumed ÷ machine-memory-size.
Cluster: memory usage:memory consumed + memory overhead.
absolute percent
RAMCONSUMED: consumed consumed Amount of memory consumed by a virtual machine, host, or cluster.
Virtual machine: Amount of guest physical memory consumed by the virtual machine for guest memory. Consumed memory does not include overhead memory. It includes shared memory and memory that might be reserved, but not actually used. Use this metric for charge-back purposes vm consumed memory = memory granted - memory saved due to memory sharing.
Host: Amount of machine memory used on the host. Consumed memory includes Includes memory used by the Service Console, the VMkernel, vSphere services, plus the total consumed metrics for all running virtual machines. host consumed memory = total host memory - free host memory.
Cluster: Amount of host machine memory used by all powered on virtual machines in the cluster. A cluster's consumed memory consists of virtual machine consumed memory and overhead memory. It does not include host-specific overhead memory, such as memory used by the service console or VMkernel.
absolute kiloBytes
RAMACTIVE: active active Amount of memory that is actively used, as estimated by VMkernel based on recently touched memory pages.
Virtual machine: Amount of guest “physical” memory actively used.
Host: Sum of all active metrics for all powered-on virtual machines plus vSphere services (such as COS, vpxa) on the host.
absolute kiloBytes

CPU resource

Metric Group CPU VMware Counter Notes Stats type Unit
CPUMHZ: usagemhz usagemhz CPU usage, as measured in megahertz, during the interval.
Virtual machine: Amount of actively used virtual CPU. This is the host's view of the CPU usage, not the guest operating system view.
Host: Sum of the actively used CPU of all powered on virtual machines on a host. The maximum possible value is the frequency of the processors multiplied by the number of processors. For example, if you have a host with four 2GHz CPUs running a virtual machine that is using 4000MHz, the host is using two CPUs completely. 4000 / (4 x 2000) = 0.50
rate megaHertz
CPUUSED: used used Time accounted to the virtual machine.
If a system service runs on behalf of this virtual machine, the time spent by that service (represented by cpu.system) should be charged to this virtual machine. If not, the time spent (represented by cpu.overlap) should not be charged against this virtual machine.
delta
CPURUN: run run delta millisecond
CPUWAIT: wait wait CPU time spent in wait state.
The wait total includes time spent the CPU Idle, CPU Swap Wait, and CPU I/O Wait states.
delta millisecond
CPUINTRA: usage usage CPU usage as a percentage during the interval.
Virtual machine: Amount of actively used virtual CPU, as a percentage of total available CPU. This is the host's view of the CPU usage, not the guest operating system view. It is the average CPU utilization over all available virtual CPUs in the virtual machine. For example, if a virtual machine with one virtual CPU is running on a host that has four physical CPUs and the CPU usage is 100%, the virtual machine is using one physical CPU completely.virtual CPU usage = usagemhz / (# of virtual CPUs x core frequency).
Host: Actively used CPU of the host, as a percentage of the total available CPU. Active CPU is approximately equal to the ratio of the used CPU to the available CPU. available CPU = # of physical CPUs x clock rate 100% represents all CPUs on the host. For example, if a four-CPU host is running a virtual machine with two CPUs, and the usage is 50%, the host is using two CPUs completely.
Cluster: Sum of actively used CPU of all virtual machines in the cluster, as a percentage of the total available CPU. CPU Usage = CPU usagemhz / effectivecpu
rate percent
CPUREADY: ready ready Percentage of time that the virtual machine was ready, but could not get scheduled to run on the physical CPU. CPU ready time is dependent on the number of virtual machines on the host and their CPU loads. delta
CPUCOSTOP: costop costop delta millisecond

DISK resource

Metric Group DISK VMware Counter Notes Stats type Unit
DISKREAD: read read Rate of reading data from the virtual disk. rate kiloBytesPerSecond
DISKCOMMANDABORTED: commandsAborted commandsAborted Number of SCSI commands aborted during the collection interval. delta number
IODISK: read+write totalReadLatency Average amount of time for a read operation from the virtual disk. Total latency = kernel latency + device latency. absolute millisecond
DISKLATENCYWRITE: totalWriteLatency totalWriteLatency Average amount of time for a write operation to the virtual disk. Total latency = kernel latency + device latency. absolute millisecond

NET resource

Metric Group NET VMware Counter Notes Stats type Unit
NETDROPPEDRX: droppedRx droppedRx Number of receive packets dropped during the collection interval. delta number
NETDROPPEDTX: droppedTx droppedTx Number of transmit packets dropped during the collection interval. delta number
IONET: received+transmitted received Average rate at which data was received during the interval. This represents the bandwidth of the network.
Virtual machine: The rate at which data is received across the virtual machine's vNIC (virtual network interface controller).
Host: The rate at which data is received across each physical NIC instance on the host.
