Performance

Field	Description
Account	Customer Account Details
Duration Start/End time	Timestamp of when the project collection started and ended
Physical Servers and Virtual Machines	The sum of physical (bare metal) and virtual servers (direct connection to the VM)
Local Disks	The total number of local disks for all hypervisors, physical servers and any virtual machine that was directly targeted by the collector over the entire collection period.
Shared Cluster Disks	The total number of shared cluster disks all hypervisors, physical servers and any virtual machine that was directly targeted by the collector over the entire collection period.
Collector Runs	The number of collections used to create this project.
Used Local Capacity	Sum of Used Capacity that is local to all hypervisors, physical servers and any virtual machine that was directly targeted by the collector over the entire collection period.
Used Shared Capacity	Used capacity of the SHARED cluster disk – note in the XLSX each shared cluster disk will be present for each server it is connected to. The used capacity is shared among each server attached to that individual disk, therefore the used capacity is for each individual device name, one disk per device name. i.e. if there are 8 shared disks but 150 servers attached to those disks, add up the used capacity for the 8 disks only
Peak Disk Throughput	Sum of the read and write Disk Throughput at Peak
IOPS – peak and 95%	Sum of the read and write IOPS at Peak and then calculated at 95%
Read/Write Ratio	The percentage of read operations and write operations between the server and storage devices based on the top 10% of IO records by IOPS.
Average Daily Write	The average number written to disk per day. Blog post: https://support.liveoptics.com/hc/en-us/articles/360000498588-Average-Daily-Writes
Peak Aggregate Network Throughput	Sum of the read and write network Throughput at Peak

Performance – Hypervisors (top panel)

Field	Description
Hypervisors	Number of Hypervisors in the project
Local Disks	Number of local disks connected to a server, desktop or hypervisor. If VM was directly targeted then disks attached to that VM are listed here
Shared Cluster Disks	Number of shared cluster disks connected to a server, desktop or hypervisor. If VM was directly targeted then disks attached to that VM are listed here
Used Local Capacity	Sum of Used Capacity that is local to each hypervisor
Used Shared Capacity	Used capacity of the SHARED cluster disk – note in the XLSX each shared cluster disk will be present for each server it is connected to. The used capacity is shared among each server attached to that individual disk. Therefore, the used capacity is for each individual device name, one disk per device name i.e. if there are 8 shared disks but 150 servers attached to those disks, add up the used capacity for the 8 disks only
Peak Disk Throughput	Sum of the read and write Disk Throughput at Peak
IOPS	Sum of the read and write IOPS at Peak and then calculated at 95% Note: Live Optics uses the nearest rank algorithm for calculating percentiles unless otherwise noted
Read/Write Ratio	The average read and write ratio as a percentage covering the time records when the IOPS for the server were >= to the 90th percentile IOPS Notes: This is not the average read/write ratio for the entire duration of the real-time collection. It is only the average for the top 10% of records by IOPS. In other words, when the server was at its busiest, this is the read/write ratio.
Average Daily Write	The average number written to disk per day. Blog post: https://support.liveoptics.com/hc/en-us/articles/360000498588-Average-Daily-Writes

Total Shared Capacity	Total capacity of all the SHARED cluster disks – note in the XLSX each shared cluster disk will be present for each server it is connected to. The total capacity is shared among each server attached to that individual disk, therefore the total capacity for that device name is only added for one disk i.e. if there are 8 shared disks but 150 servers attached to those disks, add up the total capacity for the 8 disks only
Free Shared Capacity	Total of free (unused) capacity of all the SHARED cluster disks. Total Shared Capacity – Total Shared Used Capacity.
