We’ll be discussing, “Managing Performance in a Virtual Environment.” In a virtual world, the most important metrics all boil down to one thing: Performance. Virtual infrastructure performance really determines the end user experience, and it’s the one metric that aggregates the entire infrastructure including CPU, memory, storage and network. So, the key for every virtualization administrator is to maximize performance while providing appropriate levels of availability. This includes key tasks like: • Right-sizing your virtual machines by allocating the appropriate resources • Isolating and troubleshooting performance bottlenecks • Freeing up wasted resources (like zombie VMs, idle/stale VMs, etc.) so you have plenty of resources to allocate. In this webinar, we’ll talk about how to perform these tasks and more.

11. Key Statistics – CPU/Memory Statistic What It Means Why It’s Important CPU - Ready VM stat – amount of time in ms spent waiting for CPU High value indicates bottleneck or too many vSMP VMs as VMs wait for CPU time CPU - Used VM/Host stat – amount of CPU time used in ms High value indicates VMs are saturating vCPUs and may benefit from additional vCPUs if CPU Ready is low CPU - Usage VM/Host stat – total amount of CPU usage measured as a % For VMs usage measured by host (avg. of all vCPUs), for hosts actively used percentage of total available CPU Mem - Swapped VM/Host stat – amount of mem in KB swapped to virtual swap file Large number indicate lack of physical memory or memory limits, optimally this should be zero Mem - Active VM/Host stat – amount of true host mem used by VM in KB For VMs amount of memory actively used, for hosts sum of all VM active memory plus host overhead Mem - Ballooned VM/Host stat – amount of memory in KB that is used by balloon driver For VMs this is the amount of physical memory reclaimed by balloon driver, for hosts it’s the sum plus overhead

12. Key Statistics – Disk/Network Statistic What It Means Why It’s Important Disk – G/AVG Host stat – amount of time in ms it takes to process SCSI command High latency has a big impact on VM performance, once it exceeds 30ms VMs will slow, above 50ms is severe Disk - Qued Host stat – amount of time in ms that commands spend in VMkernel queue before sent to device queue Above 5ms indicates SCSI commands spending too much time in VMkernel®, may need to increase queue depth Disk – Usage VM/Host stat – aggregated disk I/O rate measured in KBps Good general stat to show disk activity, for hosts its combined total of all VMs Disk – Commands VM/Host stat – number of SCSI commands that have been issued Another good general stat that shows disk activity in IOPS instead, for hosts its combined total of all commands sent to disk targets Net – Dropped TX/RX Host stat – number of transmit & receive packets dropped If greater than zero you may need additional pNICs in a vSwitch or receive buffers increased Net - Usage VM/Host stat – combined transmit & receive rates measured in KBps Good general stat for net activity, for VMs sum of traffic across all vNICs, for hosts sum of all traffic across all pNICs
