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

CPU|Overall CPU Contention Overall CPU contention in milliseconds.

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

VMware, Inc. 9

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|reservedCapacity_average

mem|Usable Memory (KB) Usable host memory in kilobytes.

Key: mem|host_usable

mem|Host Usage (KB) Host memory use in kilobytes.

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.

Key: summary|total_number_clusters

machines in the ESXi hosts are unable to run because they are contending for access to the physical CPU(s). This is the average number of all VMs. Naturally, the number will be lower than the highest number experienced by the worst hit VM (a VM that suers the highest CPU contention).

Use this metric to verify if the host is able to serve all of its VMs well.

When using this metric, ensure the number is within your expectation. The metric is aected by several factors so you need to watch both relative numbers and absolute numbers. Relative means a drastic change in value. This indicates that the ESXi is unable to service its VMs.

Absolute means that the real value is high. You should investigate why the value is high. One factor that impacts the CPU contention metric is CPU Power Management. If CPU Power Management clocks down the CPU speed from 3 GHz to 2 GHz that reduction in speed is taken into account. This is because the VM is not running at full speed.

currently used by the VM memory control. This memory was reclaimed from the respective VMs at some point in the past, and was not returned.

Use this metric to monitor how much VM memory has been reclaimed by ESXi through memory ballooning.

The presence of ballooning indicates the ESXi has been under memory pressure. The ESXi activates ballooning when consumed memory reaches a certain threshold.

Look for increasing size of ballooning. This indicates that there has been a shortage of memory more than once. Look for size uctuations which indicate the ballooned out page was actually required by the VM. This translates into a memory performance problem for the VM requesting the page, since the page must rst be brought back from the disk.

Summary Metrics for Host Systems

Summary metrics provide information about overall host system performance.

48 VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Metric Description

* Summary|Number of Running VMs This metric shows the number of VMs running on the host

during the last metric collection time.

Large spikes of running VMs might be a reason for CPU or memory spikes as more resources will be used in the host.

Number of Running VMs gives you a good indicator of how many requests the ESXi host must juggle. This excludes powered o VMs as they do not impact ESXi performance. A change in this number in your environment can contribute to performance problems. A high number of running VMs in a host also means a higher concentration risk, as all the VMs will go down (or be relocated by HA) if the ESXi crashes.

Look for any correlation between spikes in the number of running VMs and spikes in other metrics such as CPU Contention/Memory Contention.

Key: summary|number_running_vms

Summary|Maximum Number of VMs Maximum number of virtual machines

Key: summary|max_number_vms

* Summary|Number of vMotions This metric shows the number of vMotions that occurred in

the host in the last X minutes.

The number of vMotions is a good indicator of stability. In a healthy environment, this number should be stable and relatively low.

Look for correlation between vMotions and spikes in other metrics such as CPU/Memory contention.

The vMotion should not create any spikes, however, the VMs moved into the host might create spikes in memory usage, contention and CPU demand and contention.

CPU Usage Metrics for Cluster Compute Resources

CPU usage metrics provide information about CPU use.

Metric Description

CPU|Capacity Usage This metric shows the percentage of the capacity used.

Key: cpu|capacity_usagepct_average

* CPU|CPU Contention (%) This metric is an indicator of the overall contention for CPU

resources that occurs across the workloads in the cluster. When contention occurs, it means that some of the virtual machines are not immediately geing the CPU resources they are requesting.

Use this metric to identify when a lack of CPU resources might be causing performance issues in the cluster.

This metric is the sum of the CPU contention across all hosts in the cluster averaged over two times the number of physical CPUs in the cluster to account for hyper-threading. CPU contention takes into account:

CPU Ready

CPU Co-stop

Power management

Hyper threading

This metric is more accurate than CPU Ready since it takes into account CPU Co-stop and Hyper threading.

When using this metric, the number should be lower than the performance you expect. If you expect performance at 10%, then the number should be lower than 10%.

Since this value is averaged across all hosts in the cluster, you may nd that some hosts have a higher CPU contention while others are lower. In order to ensure that vSphere spreads out the running workloads across hosts, consider enabling a fully-automated DRS in the cluster.

Key: cpu|capacity_contentionPct

* CPU|Demand (%) This metric is an indicator of the overall demand for CPU resources

by the workloads in the cluster.

It shows the percentage of CPU resources that all the virtual machines would use if there were no CPU contention or CPU limits set. It represents the average active CPU load in the past ve minutes.
