Metric Definitions in

vRealize Operations Manager 1

Metric denitions provide an overview of how the metric value is calculated or derived. If you understand the metric, you can beer tune vRealize Operations Manager to display results that help you to manage your environment.

vRealize Operations Manager collects data from objects in your environment. Each piece of data collected is called a metric observation or value. vRealize Operations Manager uses the VMware vCenter® adapter to collect raw metrics. vRealize Operations Manager uses the vRealize Operations Manager adapter to collect self-monitoring metrics. In addition to the metrics it collects, vRealize Operations Manager calculates capacity metrics, badge metrics, and metrics to monitor the health of your system.

All metric denitions are provided. The metrics reported on your system depend on the objects in your environment. You can use metrics to help troubleshoot problems. See the vRealize Operations Manager User Guide.

Changes in Metric Availability

The CPU Demand of Recommended (%) metric is no longer available in vRealize Operations Manager version 6.x. To approximate the metric, create a super metric using the following calculations, and add it to your Views and Reports as needed.

( (CPU|Stress Free Demand (MHz)) × (CPU|Current Size in Unit(s)) ) ÷ ( (CPU|Recommended Size

(vCPUs)) × (CPU|Current Size (MHz)) )

For more information about super metrics, see the vRealize Operations Manager Information Center.

Metrics for vCenter Server Components

vRealize Operations Manager connects to VMware vCenter Server® instances through the vCenter adapter to collect metrics for vCenter Server components and uses formulas to derive statistics from those metrics. You can use metrics to troubleshoot problems in your environment.

vCenter Server components are listed in the describe.xml le for the vCenter adapter. The following example shows sensor metrics for the host system in the describe.xml le.

<ResourceAttribute key="currentValue" nameKey="1360" dashboardOrder="1"

CPU Usage Metrics

CPU usage metrics provide information about CPU use.

8 VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Table 1‑2. CPU Usage Metrics

Metric Name Description

CPU|Capacity usage CPU usages as a percent during the interval.

Key: cpu|capacity_usagepct_average

CPU|CPU contention(%) This metric shows the percentage of time the VMs in the ESXi hosts are

unable to run because they are contending for access to the physical CPUs. The number shown is the average number for all VMs. The number will be lower than the highest number experienced by the VM that is most impacted by CPU contention.

Use this metric to verify if the host can serve all its VMs eciently. Low contention means that the VM can access everything it demands to run smoothly. It means that the infrastructure is providing good service to the application team.

When using this metric, ensure that the number is within your expectation. Look at both the relative number and the absolute number. Relative means a drastic change in value, meaning that the ESXi is unable to serve the VMs. Absolute means that the real value itself is high. Investigate why the number is high. One factor that impacts this metric is CPU Power Management. If CPU Power Management clocks down the CPU speed from 3 GHz to 2 GHz, the reduction in speed is accounted for because it shows that the VM is not running at full speed.

This metric is calculated in the following way: cpu|capacity_contention / (200 * summary|number_running_vcpus)

Key: cpu|capacity_contentionPct

CPU|Demand (%) This metric shows the amount of CPU resources a virtual machine would use

if there were no CPU contention or CPU limit. This metric represents the average active CPU load for the past ve minutes.

Keep this number below 100% if you set the power management to maximum.

This metric is calculated in the following way: ( cpu.demandmhz / cpu.capacity_provisioned)*100

Key: cpu|demandPct

CPU|Demand (MHz) This metric shows the amount of CPU resources a virtual machine would use

if there were no CPU contention or CPU limit.

Key: cpu|demandmhz

Key: cpu|capacity_contention

CPU|Provisioned Capacity (MHz) capacity in MHz of the physical CPU cores.

Key: cpu|capacity_provisioned

CPU|Provisioned vCPU(s) Number of provisioned CPU cores.

Key: cpu|corecount_provisioned

CPU|Reserved Capacity (MHz) Total CPU capacity reserved by virtual machines.

Key: cpu|reservedCapacity_average

vRealize Operations Definitions for Metrics, Properties, and Alerts

Table 1‑2. CPU Usage Metrics (Continued)

Metric Name Description

CPU|Usage (MHz) CPU usages, as measured in megaher, during the interval.

Key: cpu|usagemhz_average

CPU|Wait Total CPU time spent in wait state. The wait total includes time spent in the

CPU Idle, CPU Swap Wait, and CPU I/O Wait states.

Key:cpu|wait

CPU|Workload (%) Percent of workload

Key: cpu|workload

Memory Metrics

Memory metrics provide information about memory use and allocation.

VM - 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 two processors multiplied by the number of processors. For example, if you have a host with four 2 GHz CPUs running a virtual machine that is using 4000 MHz, the host is using two CPUs completely: 400 / (4 2000) =

0.50

Table 1‑3. Memory Metrics

Metric Name Description

mem|Contention (%) This metric shows the percentage of time VMs are waiting to access swapped

memory.

Use this metric to monitor ESXi memory swapping. A high value indicates that the ESXi is running low on memory, and a large amount of memory is being swapped.

Key: mem|host_contentionPct

mem|Machine Demand (KB) Host memory demand in kilobytes.

Key: mem|host_demand

mem|Provisioned Memory Provisioned host memory in kilobytes.

Key: mem|host_provisioned

mem|Reserved Capacity (KB) Total amount of memory reservation used by powered-on virtual machines

and vSphere services on the host.

Key: mem|host_usage

mem|Usage/Usable (%) Memory usage as percentage of total congured or available memory.

Key: mem|host_usagePct

mem|Workload (%) Percent of workload.

Key: mem|workload

Network Metrics

Network metrics provide information about network performance.

10 VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Table 1‑4. Network Metrics

Metric Name Description

net|Packets Dropped (%) This metric shoes the percentage of received and transmied packets

dropped in the collection interval.

Use this metric to monitor the reliability and performance of the ESXi network. A high value indicates that the network is not reliable and performance decreases.

Key: net|droppedPct

net|Usage Rate (KB per second) Sum of the data transmied and received for all of the NIC instances of the

host or virtual machine.

Key: net|usage_average

net|Workload (%) Percent of workload.

of the host or virtual machine.

Key: disk|usage_average

disk|Workload (%) Percent of workload.

Key: disk|workload

Summary Metrics

Summary metrics provide information about overall performance.

Table 1‑6. Summary Metrics

Metric Name Description

summary|Number of Running Hosts Number of running hosts.

Key: summary|number_running_hosts

summary|Number of Running VMs This metric shows the number of running VMs at a given point in time.

The data is sampled every ve minutes.

A large number of running VMs might be a reason for CPU or memory spikes because more resources are used in the host. The number of running VMs gives you a good indicator of how many requests the ESXi host must juggle. Powered o VMs are not included because they do not impact ESXi performance. A change in the number of running VMs can contribute to performance problems. A high number of running VMs in a host also means a higher concentration risk, because all the VMs will fail if the ESXi crashes.

Use this metric to look for a correlation between spikes in the running VMs and spikes in other metrics such as CPU contention, or memory contention.

Key: summary|number_running_vms

summary|Total Number of Clusters Total number of clusters.
