    Veeam VMware: vSphere Host CPU Ready Time Analysis

    vSphere Host CPU

    Performance

    >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]
    [VM name] - [cpuReadyPct]
    [VM name] - [cpuReadyPct]

    >90 (warning)
    >95 (critical)

    The vSphere host [host name] has high CPU Usage with a value of [cpuUsedPct value]% averaged over [NumSamples] sample(s).

    The Top [N] virtual machines for CPU usage on this host are:

    VM Name  - CPU Usage MHz
    [VM name] -   [cpuUsageMHz] MHz
    [VM name] -   [cpuUsageMHz] MHz
    [VM name] -   [cpuUsageMHz] MHz

    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%]%)
    [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]%
    [VM name] - [memoryBalloonPct]%
    [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
    [VM name] - [memorySwapRate] KB/s
    [VM name] - [memorySwapRate] KB/s
    [VM name] - [memorySwapRate] KB/s

    Veeam VMware: vSphere Host Memory Usage Analysis

    vSphere Host Memory

    Performance

    memoryUsedPct

    >95 (Critical)
    >90 (warning)

    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      
    [VM name] - [memoryConsumed] MB
    [VM name] - [memoryConsumed] MB
    [VM name] - [memoryConsumed] MB
    [VM name] - [memoryConsumed] MB
    [VM name] - [memoryConsumed] 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
    [VM name] -  [memoryAllocation] MB
    [VM name] -  [memoryAllocation] MB
    [VM name] -  [memoryAllocation] MB
