CPU Co-stop If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Co-Stop among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of time the VM is ready to run, but is unable due to co-scheduling constraints. VM with less vCPU have lower co-stop value.
Ready If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Ready among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of CPU the VM is ready to run, but unable due to ESXi has no ready physical core to run it. High Ready value impacts VM performance.
IO Wait If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU IO Wait among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of time VM CPU is waiting for IO. Formula is Wait - Idle - Swap Wait. High value indicates slow storage subsystem.
Usage CPU Usage divided by VM CPU Configuration in MHz.
Run Queue If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Run Queue among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the number of ready threads queuing in the CPU. A number greater than 2 for prolong period indicates CPU core bottleneck
Utilization Amount of actively used virtual CPU. This is the host's view of the CPU usage not the guest operating system view.
Configured Capacity Configured Capacity in GHz, based on nominal (static) frequency of the CPU
Context Switch If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Context Switch Rate, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the rate at which Operating System processes running in a CPU are loaded and unloaded. As context switch is an overhead cost, a high number will impact the application performance. The number varies per application so profile your environment to baseline the expected range.
Overlap Percentage of time where the VM was interrupted by hypervisor as it needs to perform system services on behalf of that VM or other VMs.
Memory Available Memory Available memory on the guest OS computed as a sum of guest memory standby core, guest memory standby normal, guest memory standby reserve and guest memory free counters from the virtual machine.
Page In Rate The rate at which memory pages are paged in. An unexpected high value could indicate Guest OS does not have enough cache. This can cause performance problem for memory intensive application.

Route Latency Network latency to Telegraf configured device
Route Packet Loss Packet Loss to Telegraf configured device
Note: The Route Latency and Route Packet Loss metrics are avaiable only if the PingCheck setting is enabled while configuring the Unified Access Gateway server.
Protocol Latency The time taken for Horizon protocol packets to reach destination. While related, it is not the same with protocol (e.g. TCP/IP) latency. It's a normalized average of transmit and receive packets.
Frame Rate The frequency of screen frame change per second. Higher refresh rates results in smoother visual but it requires more bandwidth.
Packet Loss Transmit The percentage of Horizon protocol packets that did not reach Horizon Client or was dropped due to out of order arrival. This number directly impacts user experience.
Packet Loss Receive The percentage of Horizon protocol packets that did not reach Horizon Agent or was dropped due to out of order arrival. This number directly impacts user experience.
Worst Latency Worst Latency from all active sessions. A user can have >1 sessions concurrently
Worst Frame Rate Worst Frame Rate from all active sessions. A user can have >1 sessions concurrently.
Worst Packet Loss Transmit Highest transmitted packet loss from all active sessions. A user can have >1 sessions concurrently. Keep this number below 1%
Worst Packet Loss Receive Worst Packet Loss Receive from all active sessions. A user can have >1 sessions concurrently.
Number of Sessions with High Protocol Packet Transmit Loss Count of Sessions with Horizon protocol (e.g. Blast, PCoIP) packet transmit loss > 1%. Expect this number to be low. In ideal state it is 0.
Number of Sessions with High Protocol Packet Receive Loss Count of Sessions with Horizon protocol (e.g. Blast, PCoIP) packet receive loss > 1%. Expect this number to be low. In ideal state it is 0.
Number of Sessions with High Protocol Latency Count of Sessions with Horizon protocol (e.g. Blast, PCoIP) latency > 180 ms. Expect this number to be low. In ideal state it is 0.
CPU Co-stop If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Co-Stop among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of time the VM is ready to run, but is unable due to co-scheduling constraints. VM with less vCPU have lower co-stop value.
Ready If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Ready among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of CPU the VM is ready to run, but unable due to ESXi has no ready physical core to run it. High Ready value impacts VM performance.
IO Wait If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU IO Wait among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the percentage of time VM CPU is waiting for IO. Formula is Wait - Idle - Swap Wait. High value indicates slow storage subsystem.
Usage CPU Usage divided by VM CPU Configuration in MHz.
Run Queue If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest CPU Run Queue among any of the vCPUs, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the number of ready threads queuing in the CPU. A number greater than 2 for prolong period indicates CPU core bottleneck
Memory Available Memory Available memory on the guest OS computed as a sum of guest memory standby core, guest memory standby normal, guest memory standby reserve and guest memory free counters from the virtual machine.
Page In Rate The rate at which memory pages are paged in. An unexpected high value could indicate Guest OS does not have enough cache. This can cause performance problem for memory intensive application.
Contention If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest Memory Contention, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the amount of time, in percentage, the VM CPU is waiting for memory to be brought in. Keep this number below 1%.
Page Out Rate per second The rate at which memory pages are paged out. An unexpected high value could indicate Guest OS is under memory pressure. It's a capacity, not performance metric.
Utilization Amount of memory utilized by the Virtual Machine. Reflects the guest OS memory required (for certain vSphere and VMTools versions) or Virtual Machine consumption.
Configured Capacity Memory resources allocated to the Virtual Machine.
Usage Memory currently in use as a percentage of total available memory
Disk Disk Queue If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest Disk Queue Length, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the number of outstanding requests + IO currently in progress.
Latency If you have enabled the peak metric collection for vCenter VMs, this metric is set to the highest latency among any of the virtual disks, measured as peak of any 20-second average during the collection interval. If the peak metrics are not enabled, this metric is set to the weighted average of read latency and write latency.
Read Latency Average amount of time for a read operation by the storage adapter.
Write Latency Average amount of time for a write operation by the storage adapter.
Performance Datacenter KPI The Key Performance Indicator, aggregating all the performance metrics into 1 metric. This focuses on the network segment of session, as opposed to the datacenter. Value is 0 - 100% and divided into 4 levels (Green 75 - 100%, Yellow 50 - 75%, Orange 25 - 50%, Red 0 - 25%).
