Veeam VMware: vSphere Host CPU Ready Time Analysis

vSphere Host CPU

Performance

cpuReadyPct

>15 (warning)
>25 (critical)

The vSphere host [host name] has overall high CPU Ready Time with a value of [cpuReadyPct value]% averaged over [NumSamples] sample(s).

This can indicate that the host has issues scheduling CPU for VMs.

The Top [N] impacted virtual machines on this host are:

VM Name - CPU Ready %
[VM name] - [cpuReadyPct]
[VM name] - [cpuReadyPct]
[VM name] - [cpuReadyPct]

Alert Description

Veeam VMware: vSphere Host CPU Overcommit Analysis

vSphere Host

Configuration

CPU Pressure

>150 (warning)

 

 

The vSphere host [host name] is heavily overcommitted for CPU. The CPU pressure rating is [cpuPressure]%.

High CPU Pressure means a high ratio of VM vCPUs to host physical CPU cores. High values may cause performance issues in vCPU scheduling.

The Top [N] running VMs on this host for allocated vCPUs are:

VM Name – vCPU Count
[VM name] -   [CPUCount] ([cpuReady%]%)
[VM name] -   [CPUCount] ([cpuReady%]%)
[VM name] -   [CPUCount] ([cpuReady%]%)

Veeam VMware: vSphere Host Memory Ballooning Analysis

vSphere Host Memory

Performance

memoryBalloonPct

> 50 (warning)

The vSphere host [host name] has ballooned [memoryBalloonPct value]% of its total memory averaged over [NumSamples] sample(s).

High memory demands from VMs are forcing the use of memory ballooning. This can cause performance impact such as pagefile use and high disk I/O within the VMs.

The Top [N] impacted virtual machines on this host are:

VM Name - memory balloon %
[VM name] - [memoryBalloonPct]%
[VM name] - [memoryBalloonPct]%

Veeam VMware: vSphere Host Memory Swapping Analysis

vSphere Host Memory

Performance

memorySwapRate

> 1000 (error)

The vSphere host [host name] has a swap rate [memorySwapRate] KB/sec of memory to disk.

High memory demands from VMs are forcing the host to use its swapfile. This can cause serious performance impact.

The Top [N] virtual machines forcing swapping on this host are:

VM Name – memory swap rate KB/s
[VM name] - [memorySwapRate] KB/s
[VM name] - [memorySwapRate] KB/s

The vSphere host [host name] is using [memoryUsedPct]% memory, averaged over [NumSamples] sample(s).

Host is currently has only [memoryAvailMB] MB of free memory available.

The Top [N] virtual machines consuming memory on this host are:

VM Name  –  memory consumed MB

Veeam VMware: vSphere Host Memory Overcommit Analysis

vSphere Host Memory

Configuration

memoryPressure

> 150 (warning)

The vSphere host [host name] is heavily overcommitted for memory. The memory pressure metric is [memoryPressure]%.

This does not indicate immediate performance issues, however memory overcommitment increases the risk of ballooning and swapfile usage if VMs start using their memory allocation.

The Top [N] virtual machines forcing memory pressure on this host are:

VM Name – Allocation MB      
[VM name] -  [memoryAllocation] MB
[VM name] -  [memoryAllocation] MB
